I'm Putting a ka24de out of a 92 s13 with an A/T in an 89 s13 with a M/T. I've got everything together and hooked up right (as far as I can tell) but the damned thing won't start.

I had to use the wiring harness out of the 92 and had to splice a few wires because of the plug from the engine harness to the main harness is different.

A friend of mine said he heard something about having to disconnect the Tach. Does that make any sense???

please help

 

I forgot to say the engine is deffinately good because we were just driving the 92 until about a month and a half ago when the tranny died. also the starter is turning over but the car won't start

 

You'll have to swap out the ECU as well. As the 89 was a SOHC, and the 92 is a DOHC.

 

You will need a tach from a DOHC cluster.

 

another problem i ran into that i forgot to mention is on the plug to the main harness that s different has some extra wires that don't go into the dual cam harness. I don't have my wiring diagrams with me but i remember one of the wires that i don't have hooked up goes to the AIV sol.(what in the world is an AIV solonoid?)
Those wires that don't go into the to the twin cam harness, do I need those to hook up to make the car run???
