I am having trouble locating my coil hot, o2 hot and iacv hot wires. They are supposed to be in these two plugs from the S13 sr20 harness.
The coil hot off of ignition is supposed to be a Blue with Red Stripe wire coming off of the F8 (gray) plug. The IACV power is supposed to be a Black with Yellow Stripe wire coming off of the F8 plug. The O2 sensor hot wire is supposed to be Brown wire on the F10 plug.
As you can see from the pics I do not have any of the wires. I was told that this motor and harness came out out of a running s13, which means the right wires must be in these plugs, but they are just a different color?
It's good you want to try figure it out yourself but just make life easier and buy a wiring specialties harness. It will be the best thing you buy for the swap.
I use wiring specialties all the time for connectors (the oil pressure sensor connector and mafs connector on this engine are from them) and if I didn't already have a useable harness I would definitely get my harness from them. This harness is installed and 90% wired. I would much prefer to just finish wiring this one up. It will be less work with only three wires left and quite a bit less cost. I am having a hard time figuring out where that blue wire with the red stripe ends up down line in the harness. If I knew where in the coil system that ignition hot ended up I could just run a new wire.
