S14 w/s14 sr20 wiring question

[cgtdream]

This is mainly a double check before i start the wiring part. Right now i am wiring a s14sr20 (zenki), into an s14(zenki) chassis..i have diagrams and pinouts for the SR f4 plug, and the KA M63 plug...But now i am wondering what else is there to wire?

There are a couple of plugs in question on both harnesses....Im hoping that someone knows what they are, before i dig thorugh the fsm's searching..

Also, i have been searching around alot, and i have gotten mixed opinions on whether i can use the lower engine harness from my sr, with my "fusebox"...its really a serious thing for me, since my lower ka harness was chopped up by the previous owner, and i dont have none of the tranny plugs, or any of the fuse box plugs, save for 2...

I really hope that someone can help...

*EDIT* making a writeup whenever im done with this, cause there is too much mis-info on the net about the wiring for this swap.....

Anybody?? ??????

dude i am in the same boat as you zenki w/zenki sr. The wiring is the only thing holding me back from driving my new beast. Right now i am trying to diagnose a no spark/ no injector pulse problem. To answer your question, in the lower pic that you have those 2 relays are the eccs relay and the ignition relay. The small little gray thing connected to the 2 red wires is for the injectors i believe, Dont quote me on that though but i know you dont have to mess with it. It just gets taped up into the harness.as for the relay comming off of your dash plug and that other plug, i have no clue. I dont have that on mine, maybe its an automatic harness? or maybe its the reason i dont have spark or injector pulse, lol. Here is a color coded diagram that me and my friend were working on while going through fsm's and other posted pinouts. This is also for a zenki chassis. http://i5.photobucket.com/albums/y189/squirrel240SX/stufffffff/S14SRintoS14Pinout-Colors.jpg
take that and just move pins on the sr harness to the corresponding spots that are shown on the ka dash plug. Tip be sure to label all the wires on the harness before pullling them out and moving them.
Good luck! keep me updated!

Thanks alot guys....now im wondering if that small connector is also another relay plug??? And also what relay is beside it, that is also in the first pic?

[cgtdream]

Alrite here goes...in the first pic, the white connector is a plug that connects to the AT control unit..yahhh, so that is not nececsary...

Next, in the same pic, is a plug for both the eccs relay.

Wires, and what connectors they run to....

black wire w/white strip splice into 4 = ECU Pin 56/61 {ECCS RELAY N/O}
red wire w/black strip = ECU Pin # 4 {TO COIL IN ECCS RELAY}
red wire x2 spliced into 3?? =
-F4 PLug Pin 17 {power}
-ECU Pin 113/70 {113 is constant power 70=?}

A note on the black wire with white strip, is that once it splices into 4, 2 run into the rest of the engine harness and are black w/white strip with pink bands, while the other 2 both go to either pin on the ECCS/ECU, and are still just black and white stripped.

I found it on the net, and i it is the property of 240sx as far as i know....
