S14 harness help !!!

[Guardians91240SX]

Hey all I have a '95 (build 3/94) 240sx that I am doing a 5spd swap on. So the motor and trans swap was smooth as butter, but this wiring is kicking my butt, I still have the harness from the auto, and the 5spd harness is still on the trans, my only question is looking through my FSM, they only say E201 goes to E17......it doesn't actually say what the name is ie E17 speedometer sensor to E201 speedometer sensor etc I need help to figure out what to do with the following plugs from the 5spd harness, like i said i still have the auto harness if i need to cut and solder different plugs on




I thought the top white one was for the alternator, but i have a separate hook up right to the battery for that

and i already jumpered the interlock, but what about the rest of the plugs ?



I thought this stud was for the starter power wire ? but no nothing for it just a stud in the plastic fuse box not connected to anything



and heres a shot of the wiring nightmare as i got the motor swap, motor supposedly has forged internals and was boosted from the previous owner when my buddy the s14 (2/94) with the motor setup in it......



As you can See i have my work cut out for me, I could use any and all help, I want to keep the auto PCM for the higher rev limit and fuel cut out, but also have the manual PCM as well, I just want this car ready sooner than later, I miss the ac !!!!

Thanks,

I have the same year, but OEM 5-speed. I'd be happy to look at stuff when I get home. However, I am unclear on what your exact question(s) is (are). Can you re-phrase or clarify any of that?

E201 to E17 - you'd like this explained?
Plugs near relay box - what is your question?
More plugs near bottom of relay box - what is your question?
Relay box plugs along the side - I don't know about jumping an interlock. Identify three remaining plugs?
Relay box photo - identify post connection to anything?
Last photo, hairball hanging over passenger fender - what is your question?

Running back and forth between ECU's I won't be able to help with. Perhaps someone else can chime in on that. The 5-speed ECU rev and speed limits aren't really that restrictive imho. I've only hit the speed limiter, not the rev limiter when driving.

Maybe it will make more sense to me when I'm looking at my car. Oh, it's garbage night and I'm doing brakes, so give me a day or two.

I just need a pic of the 5spd fuse box so i can figure out what plugs into where, and what the name of those plugs are ie what they go to,

Thanks,

Okay, I don't see how this helps, but here's a pic.

Thanks for posting up Centralcoaster23, yea i was trying to figure out the ka24de development stuff plus the one off NICO, I pulled off the mini starter/OP harness from the auto, and cut the 5th gear switch from the 3 prong manual harness plug, tied ( cut, soldered, shrink wrapped) the 5th gear prong into the OP wire, pulled the whole 5spd harness wrapped it up to make it pretty,




Most of those plugs went to the damn ABS so there is a huge pile of unused plugs balled up and in the corner now till i can figure out what i can and can't cut, i hooked the plugs up from it to the fuse box and boom it fired right up, idled like crap ( with both auto and manual ecu's) then died...........but the bigger problem is step on the gas ( all testing in neutral) car dies, slowly come off the gas car revs up then dies..... the motor was a from running driving car till it got totalled, all the wiring is exactly the same, well better soldered connections now lol, the only thing i can think of is when we where bringing the motor/trans set home, some jack wagon cut us off, so we had slam on the brakes and the motor set shifted and the dizzy smacked up against the engine hoist we had next to it and broke half the plug off the dizzy, I am gonna swap the dizzy from my known good running engine and see if that fixes it.....then i'll move onto the TB, then the top feed converted RC injectors...then ???

[Guardians91240SX]

well kinda got the car to run but it still has the same issue, step on the gas car starts to die let off and it revs up a little, but ultimately still dies, I have swapped over my known good maf and dizzy and still nothing.........

[Guardians91240SX]

Now its got me thinking that the RC 270cc injectors, their spliced wiring, sketchy resistor box and fuel delivery setup may be affecting the car, I have swapped a known good dizzy, TPS, MAF and even plugs.....still the same, car starts revs up and bit, drops to a crappy idle and when you step on the gas idle drop to nothing but if you immediately let off the gas ie smash the pedal and let it go car acts like its stalling but then picks up then idle plummets again...... I may end up swapping the auto harness back over....which now looking at it I never should have pulled the damn thing !!!

Oh man, what a pita! I've been reading these, but no replying. I'm sorry, but I don't know what to do to help. I don't know how to run non-oem injectors. At home on the laptop I have some photos of wiring harness and an excel spreadsheet. If you want, I can share my notes (warning: deciphering someone else's notes isn't always easy). It's for the engine harness, not the transmission harness, but it is the same early model s14. Shoot me a PM with your email address. I got all the connectors from Wiring specialties and intend to build a brand new harness someday.

its all good man, I pulled the manual/abs harness back out of the car and swapped a few "better condition" connectors over to the stock non-hacked harness, with lots more soldering, marine shrink tubing and a roll of electrical tape and split plastic convoluted tubing later I have a pretty harness, I will post a pic of it and the results from the install later once I get off work,
