I have a 1996 s14 with a s13 ka24de in it (whoever i bought it from cut the harness to fit the motor and now my car won't start).
Well I can connot tell you all the wires will work. Here is my question. Is the engine the same year of the body? Cause from year to year they change the wiring and pluges. You hap to use all the electric parts in that year of the body. Most peoplle don't know the plug end of the wires can be change. Plus newer hard ware will not work on older wiring and the solf wear. Nor will old hard wear and solf wear will work on newer system. That why the mechanic changes the electric hard over to the engine going in. If there is a wiring shop in your area for automtive. It would be the cheapest place to go to have it repair and wired right. 12 votage to a smal amp wire can burn the computer up. Diagram for the wiring is hard to fine. Most shop do even have it. Only wiring shop seem to have them. Guess is so people cannot over ride alarms system and take someone less vehicle. What is out there is pice mill at best.
