s13 sr20det into S14 Ignition hot to coil wire missing

[jonny96]

I am wiring up an s13 sr20det into my usdm s14. My F8 connector does not have the blue wire with the red stripe to send ignition hot to the coil. Did Nissan use another color wire to this plug on some models for the ignition hot to the coil? I have found pictures of F8 plugs that do not have the blue wire with the red stripe, but the post in which I found them does not specifically address this issue. Any help would be much appreciated.

In the USDM models, there are no provisions to power the coil packs via the ignition fuse in the fuse box. What most guides will tell you to do is to tap the blue/red wire on your EFI harness from some other switched 12V source (most typically say to use the black/red supply). Another option is to run a wire straight from the battery positive terminal to the blue/red wire, but if you do that, I highly recommend running an inline fuse.

The blue wire with the red stripe that sends the ignition hot to the coil packs (probably actually to a relay) is not in the F8 connector on the wiring harness that I got with my SR20det motor. The F8 connector looks to have been unmolested. Is it possible that another color wire was used for Ignition hot to coil packs in that F8 connector in some models? If I can't trace the wire down to one of the wires in my F8 connector where does that blue wire with the red stripe end up? I'll just run a new wire if I have to, but I'm having a hard time figuring out where in the coil pack system that wire ends up.

These are my F8 and F10 plugs. After deciding to just wire up the rest while I try to figure out where my coil hot wire is I realized I'm also missing the sensor hot wire and IACV power.

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?

Any help would be much appreciated.

Looks like the image hosting site I used on the previous post did not work. Here are the pics again.
