Does anyone know what wires are what on a 91 240sx le? Whoever owned my car before me was dumb and cut the harness off, so now I have no idea what wires go to what. Thanks for the help.

 

Download the FSM there should be a diagram with the ECU pinouts... but depending on where the harness was cut, the rest of the wiring might be a nightmare. Personally if I was in your situation, I'd go junkyard it and pull a complete, uncut harness from a donor car (we did this with a friends S13 when we swapped from SOHC to DOHC, and it was plug and play)

 

Ok since I'm kinda new here, what's an FSM..I think that's a factory service manual? It's just cut right at the end where the old harness was (I guess he didn't think he could get a harness adapter for 2 bucks? Junkyard sounds good also. Thanks.

 

yes, FSM is a factory service manual. There's scanned .pdf versions online for free

 

And where might I find this FSM?

damn all this time I was talking main harness... didn't notice I was in "audio" section. Sorry about that.

Anyhow, I didn't have an S13 wiring table, so I couldn't have helped anyways. Good to see cd1921 helped ya

 

Does anyone have the wiring diagram for a 89-90, or is it the same as the 91-92?

 

Just a correction to the wiring....
