Mine ended up being the wrong year cluster. It's an 03 cluster in an 07 classic truck. They used different alternators so it's confused.

🫣

Might be slightly different because yours is carb correct? And this 98 is most definitely efi

Agreed. Similar, but should be close. Just take your time.

The wires shown are the only wires needed for the bench harness. Other grounds, power wires and such are not needed for strictly reading/writing to the pcm.

Yeah, that's not a very common one. I am assuming you are just doing a pcm replacement for your S10?

@@macsboneyardbuilds Nope I cant afford to replace it on disability pay, I just need to disable vats so I can start my truck, I have doctors appointments to get to... I've tried to do every relearn procedure out there with no luck... The truck starts than stalls right away I'm getting a P1632 code... The trucks been flawless for 7 years... This computer stuff is annoying to me... Give me an old fashioned chevy 350 with points and I can get it running in my sleep, add all these sensors and computers and I'm lost... Vehicle computers are not like the Linux Linux and windows based computers I worked on for years... I have been wondering if its possible to put a more modern PCU in it without to much headache, but as I said that's beyond the scope of anything I know and have not ran across anyone online doing it...

Over charging alternators is usually caused by the voltage regulator on the alternator. I couldn't see 3 different alternators having bad regulators. But GM also had the battery control module on the negative cable on later years. May want to try swapping that out. Did you try and clean up all the grounds you can find. Bad grounds will create havoc on all types of battery behavior

I'd love to do these for people if I had the time. Unfortunately, time is my enemy, and I can't dedicate enough of it to do them. I have faith everyone can do them with time and patience

Thank you. It wasn't a grand makeover but enough to make the space much easier on the eyes.

Did you clean out the metal tube from the intake to the egr. This one took almost a whole can of break clean and was nasty. It may have dirtied up the egr already.

@macsboneyardbuilds I didn't do a thorough clean, I should have known better. However, the check engine light turned off on its own today while driving. But I will consider cleaning the egr tube.

@crcor2572 Thank you, appreciate it.

I hear ya. The clean work space definitely makes you more motivated. Good luck on the Jeeps, and thanks for subscribing!

That wire is a fusable link and can go bad. Mine ended up being the wrong year cluster for the truck.

I would love to, but I barely have enough time to tinker on my own projects. It may seem intimidating, but with a little time and some trial and error, you can do it.

You bet 👍

There is absolutely nothing wrong with a good 350. I would have stayed with the 350 longer if the trans hadn't gone out on me. That was the domino that fell that set me into motion to do my swap.

As long as it gets 13 smiles per mile it's a win 👍

@@MultiTazmo not a bad idea at all

Not sure on that one. Could try it, but I would be careful; it may brick it and make it inoperable.

You have some serious saliva. Haha

Yup, on the 350 it had originally just ran the breathers. Sometimes modern technology isn't so modern.

You know I haven't tried. I believe you can, and I plan on swapping out to electrical at some point on my C10. (As in, I've had the fans sitting in the corner for a year 🤦‍♂️)

Thank you. I'm just a guy who likes wrenching on a budget who tries to help others with tricks and hacks I learn along the way.

Bulkhead connector diagram

I'll try to poke around in my spare time. Try and find a 95 gm service manual online. It would have the schematic in it

@@macsboneyardbuilds I found the manual but it still showing wires I don’t have for example a-2 no wire on my bulkhead but it shows a wire on the diagram… I don’t know if I’m looking at the v-8 wiring diagrams or what

Do you have a backprobe, or wire chaser. You may have to do it the tried and true method and just start testing which wires in the cab coordinate with the wires in the bulk head. Slow and tedious, but it works. I agree, I've poked around the net looking for what you need, and it is not readily available like many others.

I appreciate it. Been busy, but will hopefully get back after it soon.

Same!!!!

Yes. I used 2.5 pipe welded to the flange which sat just on the outside of the hole on each side.

@@macsboneyardbuilds awesome. thanks a lot, man!

No problem 👍

@86calcutta yes, older gauges and sensors are going to give off not true readings. That's why if you see low oil pressure for example, the first thing to do is to check with a mechanical test gauge. A lot of times, it's not actually low. It's just a bad reading. Plus, aftermarket sensors, even new Delco parts, are known to be cheaply made and not as reliable as they were 20 years ago.

The model I have is just plug it in and it's on nonstop. The manual may be generic to cover multiple models, which some may have an automatic feature. Always watch your water level, if it runs dry it'll burn up before you know it.

@@macsboneyardbuilds Many thanks!

Exactly. A 5.3 vs an older 350 both in stock form is day and night. Wiring isn't bad. LT1SWAP.COM is your friend and just take your time.

Take note I did not change my cluster out my problem is just a unknown charging grimlin running around

Be sure to clean all your grounds. Back of motor, under drivers side, everywhere. Sometimes, if one has a poor connection it will throw the code. I know the battery light on these trucks is super touchy

Update on my new alternator and new battery ive cleaned ground wires I unhooked my battery ground wire while running it took a minute or so running but it did die with the ground cable off now according to my old shade tree alternator testing days that indicated a bad voltage regulator inside the alternator its under warranty I'm taking it back and trying another one

Up date again one more alternator still same thing battery light comes on still discharging dash shows security lock light on what am I missing here I've cleaned both hot and ground connections that I can get to easy I do have a bad passengers side window motor even covered up during rains it still gets wet would that set off a code the truck has been wrecked on drivers side before I owned it some one guve me some good starting points here two brand alternators new battery nothing is fixing my problem I have a heavy arc hooking the ground back to battery

No problem, I'm glad you liked it

Came with o rings. I found gaskets on ebay that had the provision for the ring, but sealed all around the flange. They were like $7 and I have more faith in a gasket over an o ring on exhaust. They have worked out well so far for only $120.

@@macsboneyardbuilds I just bought 85 c10. Comes with a 305 I want to swap it for a 6.0 and transmission also. Any suggestions

Get a 6.0 out of a 2500 truck/suburban/van, a denali, or a escalade and a 4l80e. You'll be going from like 150hp in that 305 to over 350hp. It'll feel like a rocket, haha.

I believe 10, it's not the latest and greatest. The PCs I use are hand me down/refurbished ones for like $95.

@jonsvideos321 absolutely. Yes any modern computer will do and the files are small in size so don't worry about a massive HD either.

There are no pin outs for the abs on the old or new engine ecu. The bcm must work its magic with the sensors.
