Wondering where these wires go... (Pics inside)

[pumpiniron]

I am almost done with my RB20DET swap in my S13... I am wondering where the following wire connectors go (if they go anywhere at all) so I took some pictures in hopes that some of you might be able to help me... Please note that ALL of these connectors are coming from the ECU harness on my RB20DET...



Any help would be much appreciated!

1. wiper motor2. alternator missing a wire???3. o2 sensor4. wiper motor 5. maf These would be my best guesses. On my s14 I ended up with two plugs for the wiper motor. One works and one doesn't.

My initial guess on picture number one is that it would be the wires that you have to splice into the KA gray plug... You know the 8 pin one? I would look for wiring diagrams but where do I even begin to find wiring diagrams for a JDM RB20DET!? Especially in english...

I looked up the plug your talking about, but I can't tell all the wire colors in the picture. There should be 7 wires going to the plug with the top right spot empty if your looking at the side where the wires come out. There should be G/OR=neutral switch, LG=A/C relay, SB=P/S switch, W/PU= Power to ignition coil relay, B/R Ignition switch(on signal), WB Power to ECCS relay, injectors, and backup power to ECU. I cut the plug off a long time ago or I would take a look at it for yah. Hope this helps.

I'll go inspect it further and take a better picture of it if I can... I'll check out the wire colors that you said and see... Thanks for the help, I'm actualyl getting somewhere now!
