4.3L V6 wiring diagram

[Thorwon]

Has anyone got a wiring diagram/pinout for a 2002 4.3L V6? I'm building a harness to run a 4.6L Jeep stroker engine in a 1988 Comanche.
I tried running it on a 2004 P59 and the computer went bad. 3 of the injector wires started back feeding to the injectors. As much as 1.8 volts.
I want to try a P01, which I have 2 of. It's a much simpler computer and I think it'll do just fine, if I can find a pinout for it.
I'm looking at using the 12212156 OS, which I have the 4.3 version of.

I can get specifics from SI if needed but that's essentially Alldata.. powertrain diagrams should have what you need..

I think better use P10 -P12 from trailblazer
They also cheap but they have 6 ignition outputs while with P01-59 we still tied to 1 coil and that's annoying

6 you say? Sounds intriguing.
Do you know what tuning support is available? Tuner Pro? XDFs?

There is some treads about p10-p12
Not so widely supported as p01-59
I wanna buy one dirt cheap )
