A couple install questions
I am going through and terminating my flying lead harness and came across a couple questions...
There are are 4 or 5 GY/R wires in the wiring diagram that aren't on the main connector and are labeled "Sensor supply via 10A fuse"...What are these wires for? I could only find one or two in the harness and it looks like the previous owner never used them as they are completely covered in shrink wrap.
Also, how can I tell if the CAS and serial cable shielding wires are grounded correctly?
Thanks!

F**K THE SYSTEM!!
Did you figure it out? There is one specifically that is GY/V? On the main fat harness.
Grey Yielded / Violet? (or Purple)
Me and a buddy were labeling everthing last night and were stuck on those few Grey yielded wires.

The grey/red wires are supplied switched 12v wires. You should have one with your INJ outputs, and sensors... others can be used with PWM's where required, all coming off of the fuse block 10a Fuse.
The Yellow/Red wire is the 12v source for your IGN outputs, aswell. Also from the fuse block.

I would personally recommend running your efan off of a separate power source, through a relay with the adequate amperage.
Something like this:
RELAY COIL:
PWM output(pulls to ground)
Grey/Red 12v source
RELAY LOAD TERMINALS:
Fused 12v from battery
12v(when relay closes) to fans

It would be for the narrow band O2, which if you're running a stand alone, isn't really all that necessary.
Wideband O2 can be wired to any of your Aux. Inputs, and more easily wired to your Spare A/D 2 which is already plugged in the harness.

A simple resistance check can tell if you shielding is grounded properly.
