    Zoom in if you can't see the colours of the stripe in the wire, they're only 1 pixel wide.

    What have you done about the turbo location/down pipe?

    Ill post a pick later today, I actually took care of the downpipe yesterday its a hack job but it should work just fine I know some other people that have done the same thing and had no side effects. Thanks for the diagram is it really that easy. I was expecting it to be alot of bs.

    I thought it was going to be bullshit hard when I started looking at the S13 wiring diagrams but once you knock out all the shit you don't need it's pretty basic. Fuel pump wire might be a different colour to what I posted, it's black/purple if it's an S14SR and diagram should be right for S13SR but don't quote me on it.

    Do what durdan says except for the red wire. The red wire goes to battery so connect to either a white wire or red/white on ecu plug on ae86.

    Junglematic taps a few wires twice which there is no need for. I don't think the tach will work if you just directly connect it, not that I've ever tried.

    All you really need to connect on the nissan side is the Ignitor power blue/red, the ignition power black/red and black/white, red to battery, orange to starter and the earths. It will run that way but you won't have luxuries like O2 heater(brown) and IACV(black/yellowdepending on where you cut this wire or if you even used it). I don't have the IACV wired and it idles so much better than my 4age without IACV. No real need for it unless you live in the cold but just plate it off and one less thing to break. This car going to be registered?

    I left out alternator wiring in my diag too but do what junglematic said.
