s14 blacktop into s14 zenki

[Luderacer14]

Ok, my turbo ka just blew and now i'm def gonna buy a blacktop, my ka engine is almost completely removed. One thing that is really confusing me right now is the wiring. Do i keep the ka harness in my car, or do i trash it and replace it with the sr20 harness, really confused. I'm not sure if you use both, or splice both the harnesses together. Can someone plz clearify this for me.

The inner engine harness off the KA is not needed, though you could keep the harness for its F3 plug if you want. The rest of the car harness is important as well as the S14 SR engine harness. Bottom line, keep everything until the car works.

I think I get it now, so I cut and trash all the wires that go to the ka engine itself, and replace it with the sr engine harness. From there, i just splice all the ka's interior functions to the sr20 ecu plug, correct??? By the way, whats the best way to remove the engine harness? I'm having a really hard time trying to figure out how to pull the harness completelly out my car.

Remove the blower motor box.

Oh, so thats how you do it, it sounds pretty starightforward. Thxs a bunch for clarifying everything, it finally makes sense to me now!
