I got an free s13 ka and transmission from my friend, so i put it in my s14. It used to be an automatic. but i swapped it to manual.. My friends also cut all the sensors and wires from my automatic transmission harnes... so i cant use that for my 5 speed.. anyways, I want to know how i can take the s13 transmission harness, and wire it up to work on my s14.

I'm not sure that i can even use an s13 harness... just because of the fact that the s14 has like 6 or 7 plugs under the fusebox for different things like the altenator and start etc.. I dont think there is even a big difference between the s13 harness and the s14.

are you talking about the engine harness or the transmission harness? if it's the engine harness, just use the s14 engine harness and ecu.. i think its 93% plug and play from there.
