RedBirdAuto I’ve been doing some research on the terminator x max. My biggest issue is did you make a stand alone harness for your obs and ls wiring then put them together? Then did you hook them up to the Holley system?
Nice, Been planning on putting a 5.3 in my 96 c1500. Nothing crazy just want to run again. Wiring scares me the most, I got an engine and complete wire harness from a 2001 suburban 4x4. Hopefully make that work.
I have been watching a lot of videos on Ls swapping the 88 through 98 c 1500. I enjoy the challenge but not the suffering of trying to figure all of this out. I can see doing my 90 c1500 soon. Thank you for the video.
Matt, of course, splice those two speed signal wires and tie them into that output wire from your terminator, you’ll get a signal for your Cruise control
@@ccmsbandfan I'll definately do that when spring comes. I may need to source a cruise module off a newer silverado that came with an LS. Apparently the cable lengths changed but he electrical didnt. Will touch on that in a future update.
With both complete trucks side by side in the shop (90 Silverado k2500/tbi5.7 and 00 Silverado k1500/5.3), 411 ecm. Of coarse, there is the motor mount plate to purchase, and a harness I will do myself. Considering a dedicated work day for a crew of one experienced mind connected to a pair of talented hands, how quick could this swap be done safely and pro-grade? Whats the cheapest? ECM flash excluded, I am going the just buy my own tune software/hardware. Thanks for the input
Awesome video. Your the first person I have seen with the terminator and using the OEM speedometer.. A video of the speedometer would be awesome..I am doing the same 6.0 swap with the terminator x max in a 1990 OBS and can't find info on a stock speedometer
On my setup I simply set the TermX to output a speedo signal on one of the outputs and then hooked that directly to the speedo wire from the factory harness. It works OK. i'm going to get a GPS speedo module from Dakota Digital and use that to run the speedo and free up a Termx output. It'll be hopefully more accurate.
FYI...when I did the elect/fan conversion on my 89 K1500 I used the fans from a LT1 Camaro/Firechicken and relayed it the same as in this video. Didn't have the A/C working at the time. Put a new A/C compressor, dryer, etc on the truck and had to add another relay to turn one fan on when the A/C kicked in. Without the extra relay to turn the fan on with the A/C compressor the high side pressure would go sky high.
After using the TermX speed output i'll be switching to this. the speedo is a little twitchy and seems to be off a bit. going to free up an output and use the DD box to run speedo and cruise.
Gotta get piping/tubing to go to a stock filter box or after market air box. Schedule 40 painted enamel black works just fine... if it melts you have issues.
I have a 1990 swap with a holley hi ram terminator mas x also but i blowing my mine too make the cruise control work do you know who can help me I would really apreciate thanks
I have a question. I own a 93 silverado with the 350 bone stock everything. Sometimes it will stroke out and start missing and even backfiring up through the intake. Then at other times it runs perfect. This drives me nuts. I know something electrical ( module ) is breaking down but which one. Anyone who may have had this problem, advice welcome. Distributor module maybe? Example, truck sits for a few days, cranks great, drive it to the store and shut it off. Come out of store, crank it up and stroke time. Can't give it any throttle because it will stumble and start backfiring. Any answers welcome !!! 👍
wait, does the old transmission bolt up to the new engine? i am planning to do this with my truck but i also want to install the new transmission. is it better to run the old transmission that is already in the truck or the one that comes with the new engine? edit: i am swapping it with the LQ9 btw.
Hey man I have a 1996 k1500 with a v6 4.3 it has a 4l60e what parts did you use to mate the stock transmission to the ls engine iam going to do a 6.0 ls swap also iam going to use the stock 4l60e and stock torque converter any help would be greatly appreciated maybe some part numbers would be very helpful I would be glad to send you some money for your time thanks
To adapt the LQ4 to the 1996 4L60-E We used an adapter kit from Advance Adapters P/N# 712500A. This gives you the correct flexplate and the piece to adapt the converter hub to the crankshaft. It worked perfectly. Thanks for watching!
Do you think you can email a copy of what u did to run speed,taco,fans on the terminator? I have same truck and just put a 6.0 in it .I jut Dont want to burn up anything, thats y im asking what and how u did it.color of wires,picture, anything would help.
Hey I have a 99-00 silverado 4.3l and I’m doing a gen4 ls3 with the 6l80e transmission and I’m stuck with what wires i need to get my cluster gauges to work. I have a stand alone harness for it but no wires for the cluster came with it
Can you ask Matt what color wire he used for the speedo hookup on his obs? I have the terminator x max, and same year truck as his ,so what every he did to get his speedo to work would really be helpful to me ..I know it goes in a output but I need know what color wire speedo is and how to..thanks
What type of terminator max did you go with? Got a part number? They got a couple different ones for my 1996 c1500 same as yours kinda. Swapping an LQ4 6.0 just needs wiring and transmission. How did the 4l60e hold? The stock tranny would work with just an adaptor and flexplate for the 4l60e?
Used the stock LS manifolds but you'll need a new Y Pipe since they don't match the GMT400 pipe. He used the stock GMT400 radiator with a universal flex hose for the bottom rad hose and the stock LS upper rad hose, which fit perfectly.
Unfortunately I wasn't there for all of his build, but you can find the wiring schematics and figure out how he pin to pin replaced everything he didn't need in the harness and married the two together.
If I list the wires I have left after cleaning out my old harness in my 98, can you tell me which ones actually connect to the Holley X Max? I am to the point where I have to start connecting the harness.
the holley manual says what it needs. key on pwr, fuel pump trigger, brake lamp signal....stuff like that, it only needs a few wires. as far as what wires on your harness do what? i can't answer that. i did this 2 years ago and definately have forgotten which wires. try to find a wiring diagram on the internet that shows the specific pinouts from the old ECM, that should help tell which wires you need.
What about an LQ4 6.0 in a 1995 Suburban k1500 -- that was last year of OBD1 vs OBD2 controller? I have a built 4L60E and 14 bolt 6 lug rear end. Thanks.
If you're going to swap in a motor then you'll be swapping in some kind of newer computer, either stock or aftermarket (holley, etc) The OEM computer will be irrelevant. As far as the swap? no problems, other than maybe headers. Schoenfeld makes swap headers but not sure they fit 4WD.
Intake Air Temperature Sensor. I believe it usually lives in the air cleaner box or somewhere between there and the intake. The holley ECU uses it and I'm sure the stock one does too.
did you get the ac working? also, gauges work?? reason i ask as i am about to install a 05 5.3 into my 98 z71.. How much extra expense was there like electrical, plugs etc? thanks
The AC works with a mess of relays. We are going to be testing a new module we found for controlling the AC....look out for that video soon. The gauges all work except the oil pressure but the handheld on the holley shows it. As for extra cost? Not sure the total. Didn't really keep track of it. Thanks for watching!
Holley has a tach output and then use an output for speedo. CTS is a 3 wire f body sensor with one wire sent to the gauge, it's not all that accurate though. I just use the holley gauge. Oil pressure doesnt work on mine but would just need to find a place for the sender and connect. Volts and fuel level worked before and after on my 96. Didnt need to make any changes.
He explains in the video that he bought a bracket from a guy that makes them to keep the stock obs ac pump location to fit onto the ls engine. Then he had to size up a belt that would fit.
I used a 2002 F body 3 wire temp sensor. 2 wires to holley, 1 to dash gauge. could also just use a second OBS sensor with an adapter on the rear of the P/S head for the dash and the stock LS sensor for the TermX
@@Matt-df5fethe dodge was actually in awesome shape but I decided to let it go to a better home. I kept the obs though, should be doing the ls swap as soon as the weather permits...
I have the Holley terminator but I’m confused where to tie into the ignition switch...id like to keep the original key switch...I’m horrible at wiring so I’m completely lost
You don't tie into the ignition switch. it just needs a key-on power source. when I stripped my OEM harness down i found a few Key-on wires that wouldn't be needed and reserved 2 of those, one for ecm harness, one for trans harness.
@@Matt-df5fe I know it has a fuel pump wire I was wondering which wire on the harness to hook it too... I tapped it into the grey wire but it wouldn’t cut the fuel pump on
Holley has the software on their website for free. It has a wizard on the handheld that will build a base map and will fire and run and adjust with closed loop. The more I use it the more I understand that for full potential it needs a proper tune.

The original OBS harness should have had 2 speed signals from the pcm to the cab, one was for your cluster the other was for Radio/TCCM/Cruise
It doesnt have a stock PCM anymore. The Holley handles Engine and Transmission control.
Matt, of course, splice those two speed signal wires and tie them into that output wire from your terminator, you’ll get a signal for your Cruise control

Matt You don’t need the whole module, just the cable from the NBS trucks. It hooks up just like the OBS oem cable
@@ccmsbandfan oh cool. I didn't know you could change the cables on the cruise box. Good to know

for speed signal, you can get a dakota digital speed box, it has multiple outputs
used that to gain speed signal to the ecu and cluster on a vq swapped nissan 240sx
After using the TermX speed output i'll be switching to this. the speedo is a little twitchy and seems to be off a bit. going to free up an output and use the DD box to run speedo and cruise.
Great build looking for suggestions on shortening the steering column on my 88 obs
Could you where hablé too make the cruise control too work?
That pulley system would work great on my 72 nova if I ever decided to put back an ac...

How did u hook up the brake lights, reverse lights?
OEM wiring, didn't have to mess with it.
What did he use for torque converter cover
I used the stock 4l60 cover and cut away the parts that were interfering with the ls oil pan away.
What’s the cost breakdown of everything?
I haven't kept a record of the total cost. between 3 and $5000 CAD off the top of my head
Which town in SK are u guys at?
Stoon
where did you get the engine from and how much did it cost you?
It came out of a 2001 GMC Sierra 2500. Paid $650 CAD for engine and harness.
Was it rebuilt or just pulled and dropped?
Would this still pass emissions? Are you using stock OBD2 port or does the terminator have its own OBD2?
All emissions systems are deleted, and Matt would have to chime in about the OBD port.
@@redbirdauto1713 thanks....i live in a state that requires emissions testing so i dont know how to go about that

No it's a self learning unit, but you can tune it to better dial it in if you wish
