please help identify wires - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey everyone, I have been trying to verify where these wires go. I have searched the FSM, as well as Battery and fusebox relocation posts for the answer with no luck.

This wire comes out of the fuse box. i belive it connects to the alternator but just want to confirm.

This wire is on the same branch that connects to the starter. I am not certain if it connects to the alternator as well or if it goes all the way to batt +.

Thanks for your help

Yes first one goes to the alternator postive post

Regarding Question 2: Hard to tell from the picture, but many folks forget that the alternator has a ground wire ring terminal (the alternator grounds itself to the engine, but the wiring harness also has an alternator ground connection).

Does your alternator have a ground wire connection yet?

IDKanything · 12-31-2019, 11:33 AM

Yes, I already have the ground at the back of the alternator its a little 12-8ga wire with a ring terminal. The second wire is a heavy gauge like a battery cable. I can take a different photo if that would help. I had to cut these down quite a bit to fit the 500kb limit of the forum.

Thank you both for the replies.

More pics plesse

Looks like it attach inside the fuse box to a fuse hard to tell

IDKanything · 12-31-2019, 05:19 PM

I figured it out, it goes from the starter to battery +. (Black w/ red)

Thank you both for helping me out.

This post helped me out as well I was wondering where that goes to just put a junction block in your car and route your batteries positive terminal to that then the alternator positive and then last the starter I think? That would work

jedi03 · 01-02-2020, 08:41 AM

imo should work, just risk as the junction block should be fused in case of overload on any of the systems so all components don't fry when something happens...

Dsmguy1993 · 01-02-2020, 10:20 AM

Yeah like an inline fuse works best forgot about that part your absolutely right id do a 100 amp battery inline fuse maybe a 80amp alt fuse and starter fuse. I learned that from watching the sr20det swap tutorial on yt tbh.

IDKanything · 01-03-2020, 06:29 PM

I'm back with another question, I know this is a ground wire but where are the two connection points other than the battery? I am thinking it should be the side of the block, to chassis then batt Neg. Is that correct?

Link to wire in question.

Thank you

The battery ground wire in question goes from the negative battery terminal, to the chassis (which I believe is around the battery tray area, I can confirm when I get home and look at my car,) then to the engine, which I'm pretty sure is the intake manifold on a S14.

IDKanything · 01-06-2020, 11:12 AM

Thank you, I wound up grounding it to the chassis then the block. I have another ground going from the intake to the chassis as well.
