Thread: Name these wires!

I have a 96 200sx se that now has a RR, im using a b13 engine harness to convert to obd1. The problem is that im not getting power to my ecu or fuel pump. Can you guys help me find out what these wires are and what they do? ive been searching on the forum and trying to find out whats what but not luck soo far....

Here are a few pics of the b13 connector on the ecu side of the harness.





Its basically...(excuse the 3rd grade artwork)



Here is the b14 underdash plug..



Basically....

If you can trace the wires from the first plug to the ECU you can use these diagrams to find out what it's for. You may want to save the first one and rotate it.

i checked and some of the wires arent going to the ecu... i will find out exactly which ones and let u guys know.

Hey BenFenner do you have a wire diagram for a 96 200sx?

No, sorry. =(

oh ok i dont know where those Red/blue and Blue/ Red wires go....The black Yellow stops at the plug, and the Black/ Red goes thru the harness directly to the ignition coil on both ga and sr harnesses.

Any idea if that black/red a switched 12V?
