L31 into an '86 Regal Limited V8

anything?

What number ECM do you have that might explain the differences in colors of the wiring.

Ill compare your pinouts to the ones on my truck to see if they are the same. Ill also post the number on my ECM tomarrow eavening.

Maybe I missed it... why are you tracing down all this wiring again?

To figure out what pins to take out of the ecm connectors for things I won't need/use like O2 sensors after cats, emissions stuff, etc.

But I don't know what all I won't be needing/using.

I know this engine is pretty much a stand alone, self-contained unit,
But what won't I need, & thus can remove??

Should I get the ecm reprogrammed first, or at least talk to someone that does it about what I will & won't need to make this engine run.

I just compared the pinouts on my truck and its the same exact wiring you have. I am confused why so many discrepancies in the wiring schematics.

Yes. Absolutely. Definitely. Yes.
Also, if your donor truck had a Passkey (anti-theft) system, it'll need to be programmed out. Otherwise your car won't start unless the entire system is present and active.

Where can I find a place that re/programs ecm's in Atlanta?? I googled and came up with nothin.

How would I know if my old truck had a "Passkey"? It was my truck, I totaled it, its since been junked.

I'ma try to get another wiring diagram from somewhere else. I'll look for the Mitchell one this time.

Also, is this that much of a rare swap??

Why isn't there hardly any info on this swap into G bodies?

I see F bodies, jeeps, chevelle's, even el Camino's (I know its a g body, but there are considerable differences concerning swaps).

What gives?! I know there are more mechanically inclined people that wanted to keep the fuel injection????

Thats what i used Mitchell from the local library and there is still a lot of differences, such as the red connector pin 8 is injector 1 control, but on cheap chiltons it says that pin 3 is injector 1. That explains the black wire you have there.
