Doing a complete body off frame conversion on a s10 extreme got the engine and 4l60e trans from a 96 buick roadmaster came complete as engine trans and engine wiring harness with ecm.I have all the frame done and completed with the engine and trans fit in place.What i am looking for is wiring diagrams for the 96 engine and trans.Have done a cpl of the older tpi swaps into the early body s10s with not much wiring problems at all with a little reading and studying diagrams.I'm reading and hearing that i will have to use two ecms one to run the trucks abs cruise and a few other things and the 96 ecm for the engine,trans,and ac.Building the truck to look as stock as it was and as close to what it woulda been if gm had built it that way.Using catalytic converter,02 sensors,air pump abs brakes.if anyone has any helpfull hints about how to go about finding this type of info i sure would be gratefull.

I hope you get the help you need before this gets locked.Please don't take offense when it does,our mods are super guys,but they do have to follow the rules.


PS:Looks like a killer project!!

You would find better help on some of the LS1 and LT1 boards.

Sweet project good luck with it.

I'm going to hijack your thread because even though it is not about an F-body, it is relevant to ALL sawppers...

Make sure you check the block and intake numbers. You may not have a 5.7- the Caprice and Buick are notorius sources for so-called 5.7 motors that turn out to be a 4.3 upon closer inspection.
