3.4 swap wiring question (1 Viewer)

[drcaduceus]

I did a ToyOnlySwaps.com 3.4 swap into a 1992 manual pickup a few years back. Everything worked great. That truck was in a crash and I ended up swapping a 1993 cab from an automatic truck onto this manual truck. Now the instrument cluster doesn't work nor does the AC. I assume it's because of the manual engine harness and ECU going into an automatic wiring harness in the cab. My question is, what can be done about this - short of rewiring the cab completely? In particular I would like to get the AC working again. Any advice would be greatly appreciated.

Any way you can put the original working harness in? If not I think you will need to get schematics for both and figure out what's different. Good luck with it.

get a schematic for both variants and compare them.

If It was me I'd send the harness back to toy only swaps and get them to re-make it for you. I know they take a bit of time but they really do know their stuff.
