ok I think I found the problem, tell me if this sounds right. On the 86 t1 engine there was a ais plug (2 wire) and a tps. (3 wire) Thoes 2 plugs went to another 6 prong plug (one was unused) and from there to the lm. (This is what i gathered from my fsm) I looked under the hood of my can and can find the 6 prong plug, i guess im missing the other side that has the ais and tps plug on it. Can I use one from a carbed car from the same year or do i need one from a turbo car. The other question is could I just tap into the plug i already have?
