includes c104 2.2 and 4.3

Is there any chance you have this information, but for the 94-95 2.2? I believe they changed after that and were different before that. I've been searching for ever it seems like trying to find this information but I've had next to no luck.

Sorry for Necroposting.

Is it a 94 or 95, big difference electrically. Actually 96 and 97 are also different from each other. 98, 99, and 00 are pretty similar.
In your case it would be best to contact CPW for a harness or build one entirely from scratch.
What year engine and ECM are you using for the swap?

First time posting sorry for digging deep I've got a 00 4.3 auto. Going 4.8 from a 02 1500 can you email me the pinouts I'll need thanks

Since the 99 and 00 4.3 are identical electrically, as are the 4.8 and 5.3, just follow the steps above.
It's all there.
If this is your first attempt in this arena you may have to read it over a few times to get the gist of what is happening.

I know this thread is kinda old but thank you for sharing your experience and knowledge from LT1swap, as it has helped me solve a no spark issue, which ended up being incorrect placing of some terminals in the underhood fuse block c2. Finally got the engine to actually run!!!!

I wired up my underhood fuse block c2 as described, however, now I have another issue that has me baffled...Hopefully some of you have a fix or wouldn't mind pointing me in the right direction. Here is the issue: When the key is in the "RUN" position everything works fine (fuel pump primes, all interior accessory powered devices work, engine fires up when "START" etc, etc) BUT if I put the key in and just turn it to the "ON" position, there is no power to the radio or gauge cluster lights.....Opposed to before I rewired the underhood fuse block c2. I would appreciate any help!
Also, I almost forgot, the headlights....Shouldn't the headlights come on when the key is turned to the "RUN" position? IIRC they used to before but don't now.
