Gotcha thanks man, I'm going back tomorrow to the yards ill have to see if i can find some 4x4 91 to 92sAn FYI that block at the firewall on the passenger side where the engine harness passes through - it's not actually a plug. The disconnects are inside the cab closer to the ECM. That piece that attaches on the firewall is just a chunk of plastic that seals the hole. I never looked hard enough at one to see if it could be removed without damage, to swap with the other style. Might be possible...might not. Regardless, with an earlier harness you also have that TPS difference I mentioned and possibly others.
