hey guys, i am putting an s13 redtop in my s14 and ran into some problems, i cant find the wiring diagram for the lower harness anywhere does anyone know where to get it? for the stater and alternator and sensors, also it doesnt sound like the fuel pump is working, i read that something about the walbro 255 pump doesnt work right in the s14 is that true? please help

u need to use your ka harness. u can choose to swap the sensors from one tranny to another too. u have to use ka speed sensor, but the other 2 u can just splice and wire in the matching connectors.

the pump works 100%. if it dont work its either ur pump or ur wiring.

That has nothing to do with the lower harness.

As 420 said, use the KA lower harness for the alt, starter, tranny. It shouldn't have even left the car since its attached to the fuse box, just swap over the KA sensors to the SR tranny, but the only one that really matters is the VSS on the KA, the s13 SR VSS is cable driven and obviously wont work.

im using a walbro 255 lph fuel pump in my s14 with and s13 redtop sr...it works fine

if i splice the wires are they color coded? and the speed sensor is the one way in the back of the tranny right? i sold the ka that was in the car with the tranny but i still have the tanny harness, i didnt really see anything that would have went on the sr tranny though... anyone have some pics?

then just splice the connectors to the 2 other sensors on sr tranny and wire em up to ka harness. u will see exactly what im talking about when u testfit it.

haha i really dont know, i hooked up the plug to the alternator, but there was another one on there that was a bolt and then ran up to a plug i have no place to put, and i tried to splice the sr sensors but i dont know what wires to use

so the other 2 sensors are not needed or what? i already have the motor in the car and all bolted up and just realized the lower harness is complately different. so just hook up the speedo, alt and starter and it will be ok?

not only are we talking about s13 into s14... thats not even lower harness info

edit: figured out one is reverse lights and the other is the rear o2 sensor which ive already eliminated

that is a ground. theres another stud on the alt for it, and it gets body grounded pretty much as far as it reaches up towards the engine bay
