About to go out to the garage and finish installing the terminator x on a LS swapped 86 Camaro, truck LS with a VS Racing 78/75 turbo. All i have left is locating the switched 12V wire, and 12V+ constant and it should power up. Still need to run the one wire alternator wire to the power port on the holley, but that comes after i see power to Holley.
Reason for the comment on an older video is just to say thanks, Ive referred to your videos dozens of times throughout this project. Really handy to have someone share hands on knowledge. Heres hoping all goes as planned over the next hour or so. 😂 thanks.
It’s all in the googles
All of it. All day. Everyday.
trimming down a harness is oddly satisfying for some reason, To me it is anyways. Especially when it works lol. awesome build man!
I used a heat gun to get the bulkhead apart on the one I did, then had to cut it a little to get it around the part of the harness I routed that way..
Hell I was about to throw it away and just gorilla tape around that hole but that’s a great idea! Thanks brother. 👍🏻
You make it sound so simple. ;) That is going to turn out really nice. I hate wiring mostly because I am just way too anal about it. looking forward to more progress. Heading back out into the garage. Break time is OVER! Freedom 500 will be on later gotta be ready lol.
It’s really not that hard as long as you have a pin out to go by. I’m actually still a bit confused about the speedometer wiring but other than that everything else was pretty straight forward. I’m actually about to start on the battery relocation video right now myself. Don’t have the pay per view for the Freedom 500. 😔
Awesome video!!! New to channel, love it. Working on a 92
Welcome aboard!
Thanks for the video man, just what I needed!
Glad it helped brother. 👍🏻
So i saw all the c100 hot wires went to the lug on the fire wall, which is straight from the trunk mounted battery. So the c100 power wires stay hot all the time and dont need to be a switched 12v?
Hey brother! I wonder if you can help me. I have an 85 Camaro that I am fixing up for my kid. No LS swap coz he'll just wrap it round a pole. When I turn the ignition key on, it will crank but the "Check Engine" light doesn't come on so the computer isn't working and won't start. Sometimes, if I turn the wheel it will work and it starts right up but it's unreliable. We replaced the steering wheel and I'm thinking something in the column got messed up. I'm thinking of replacing the ignition switch at the base of the column but I don't know if that will fix it since it does crank. Is there a way to jump the computer when I turn on the ignition, and if so, which wires and where? Appreciate any help you can give on this.
Just now seeing this channel hope it work for me mines a 88 RS v6 car
As long as you download the correct diagram for your car you’ll be good.
Do you run a vss on your th350 or th400 trans. Or do you change it to manual in hp tuner to keep it from stalling out coming to stops? Any help on this would be greatly appreciate. Love your channel learned a lot from you.
Both. You’re going to set it to manual because it’s no longer controlling the transmission. You can then buy a speed sensor on eBay that screws into a th350/400/glide/etc. most are 16,000ppm. You run that to your PCM as a vss input. Then set the output to 4,000ppm and run that to your factory speedometer. You can then correct for tire size and gear ratio the same way you would for any vehicle.
Bad Luck Garage awesome thanks for your reply sir.
What did you do with the red alternator wire coming out of your stock bulkhead connector?
Someone without experience or patience, could lay it out on a piece of ply, with screws and label everything first, and remove the pins, from the connectors, they may need to be reused, zipties, tape and labeling is your friend! And write things down! Especially if you are keeping everything,, especially when working with stock ecm, and harnesses!
Yea I literally just sit in a chair and as I go through the C100 block I throw the wires I’m keeping behind my neck. 🤣
Looking good!
Great video...👍 👊 😎
When I swap to 4l60e did I need to make any change on tcc
Are you on TGO? If so did you do a write up of pinning your harness???
Yes and no
After doing the c100 plug did you lose any singnl light or brake lights
The C 100 is two plugs in one. The smaller one closest to the engine has all your lighting in it you have to keep that one.
@@BadLuckGarage I kept that on the same but for some reason I have no power when I turn the key on but I have power to the horn hidlights, marker lights its my first time doing a ls swap
My brother cut the wire harness that came out the passenger side fender is there anything I need to do or just get the Holley u have it is going carb
There are a few wires you may or may not choose to use but for the most part the engine harness won’t be needed.
What did you do to the red alternator wire coming out of the c100 bulkhead connector?
If you're referring to the exciter wire, I believe I removed it. I then used a different switched 12 volt wire to trigger the LS alternator. You will need a resistor and a connector for your new alternator. I actually covered that in a later video in the Chaos Theory playlist and even put a link to the parts I used.
Hey Robert l have a 2003 5.3, lm was wondering the years of a 4l80 that would fit it okay or would be best to use?
You can use any 4L80 but the 99-up will have the extra bolt hole in the top of the bellhousing to match the top LS bolt hole. The later models also have the better rear feed system. Just look for one with the top bellhousing bolt hole AND the transmission line connections that’s are front and back instead of right next to each other.
What did you end up doing with the heavy pink wire from the c100?
Explained in the video
Wich video did you go over your alternator wiring?
I don’t remember but it’s pretty simply. Go on eBay, spend $20 on a one wire kit that comes with a resistor and the correct connector for your alternator. Run a 12v switched ignition source to the Connector through the resistor and done. Holley sells the kit but you can find it cheaper from an eBay seller usually.
@@BadLuckGarage thank you, very much appreciated my friend!!
I'm about to LS swap my 91 3rd gen Camaro it's originally a 305 with a carb, do I follow this same process?
Yes. Google diagram, get his of what you don’t need.
Where did you get that heater box?
Ebay and I don’t recommend it. I explained why in other videos.
👍😎
Hey I am currently trying to wire my c100 I have put power to both red wires and ground to both black wires. I have little power flow inside of the vehicle as in no radio works very dim interior lights. Let's just say the inside of the car is not right. Is there anything that could of went wrong. I was reading that for one of the. Black wires it is called srs should it be grounded... 92 Camaro tbi. The fuse box I made works perfect just gotta mate it to the car
I really can’t say for your particular application brother. Hell my C100 doesn’t even really match the pin out I have. As an example, the pin out says I should have two grounds coming out of my bulkhead....one labeled for engine and one labeled for the inflatable vehicle restraint. However mine had no pin in C7 which was supposed to be the engine ground. Only in F8 which is supposed to be the ground for the supplemental inflatable restraint (SIR). So F8 is the only ground I have at the C100 connector. That’s why I said in the video that I wanted to do a step by step but it would have been useless since all these cars are wired slightly different. Did your car originally had a ground coming out of F8? If it did then it probably needs it.
@@BadLuckGarage that's why I was cerous. I have the f8 black and white to ground and I have another black and white to ground. I will look at it tomorrow with fresh eyes. Probably something simple I am missing.
I’m not sure exactly how you have everything but F8 should be an engine ground, not a chassis ground. And it does make a difference.
Okay didn't know that! I will switch f8 to engine ground and see how that goes I have them both running to chassis. I will let you know how I make out thankyou.
Got another question for you. I am in the same. Build right now as you at the same stage. For the cruise control I am deleting that. there is a vaccum line running in to the vehicle. From the ball when I put a vaccum pump on it it holds vaccum do I need to put that to manifold vaccum or cap that line. And for the HVAC wires there's a vaccum line coming out of there from diagrams I saw thoes lines connect. What do I do with the vaccum line coming out with the HVAC power?
I do ls wiring and have a 91 camaro if you need any information dm me ill help you out.
Can u help me with one? My brother its in the middle of a ls swap, his 3rd gen is a rs 91
@@carlosmostro Sure what do you need.
@@MrRock861261 I got questions to
I’m gonna need some help soon... I’m ls swapping my 1991 z28
What wire goes to the starter to engage the starter?
The fat purple starter wire
Thank you. I have the same wiring diagram as you and I believe my Purple one has a larger connection same size as the battery connection so that threw me off. I will put a smaller connection on it.
If you went through your harness then it’ll most likely be too long and need to be cut anyway brother. So it’s a good time to crimp a new connector on. But it should have a fairly small connector to begin with unless the previous owner changed it.
Well shit you are going to have this thing at the track befor I can put a prefabricated Turbo kit on my truck
😂
Dam I have all my shit on it still just got the main wires out and connecting them now it’s annoying
Yea just gotta put your head down and do it brother.
Bad Luck Garage yup tomorrow morning I’ll be putting up a video
It will be cheap and it will look ugly but I’m new at this lmao
