'92 a518 vss to '97 OBD2, compatible?
Would it be any easier to find an ECM from a stick shift truck? Then you could just use the kit posted above in your 46RH, and let it do it's own thinking. I'm doing basically the same thing you are to an old 88 D150 long bed. My 5.9 Magnum motor, and every inch of underhood wiring and computer came from a 98 3500 5 spd truck. The ECM for a stick truck doesn't care what the transmission is doing as long as you have a speed sensor. My truck has an A998 or A999....whatever a lockup 904 was....lol. I'm probably gonna use it back and just beef it up. It's just an old beat around truck that hauls firewood, and stuff to the flea market.
