doing the manual conversion, right? ...so you will want a manual trans engine harness. I have an OBD2 manual trans engine harness here in our basement (it just happens to be from phoenix.. haha).. but I'd have to box it up and ship it back to you in phoenix. I only know it is obd2 though (no idea if it is 94, 95 or 96 though) We kept a spare for our former 95 G20 (all connectors are there but since its from phoenix, some of the tabs on the connectors are broken off)
I figured it was worth keeping for future (never know when we might need it for a future purchase/conversion to manual)
I just thought you would be able to find your own locally right now with 5 to 6 yards to choose from! ...last one we took from Pick-a-Part in Mesa off Extension was around $32 plus 2 hours of our own labor (no I'm not going to sell it to you for what we paid, sorry)...but that's why I suggested you check locally!
