2001 Mustang Cobra - Strange Electrical Problem

All,

I am restoring an auction-bought 2001 Mustang Cobra. The next issue I need to address is that I have no warning lights whatsoever on the right hand side of the cluster. It may be related to the fact that the cluster also takes around 15 seconds (consistently) to turn on after key-on. I replaced the cluster, and the replacement cluster did the same thing. I also had the car re-flashed in case there was an aftermarket tune; that didn't fix the problem either.

Anyone have any ideas about where I should look next?

All of the grounds checked out, including the black wire and the black and white wire.

I figured out how to put the cluster in test mode, it's giving me a 9356 code, which is ignition run circuit open. Notably, when it does the 'bulb' test, none of the bulbs light up. I put my new cluster back in and had the exact same results.

Any ideas where to look next? Was thinking about dropping the trim around the ignition switch to see if I can find any issues.

Strange thing is, the car runs and drives great now, and according to my scanner, does not throw any codes.. but it won't pass inspection if the stupid little CEL light doesn't flash. If I can't figure it out this week, I'm going to run jumper wires from the air bag light (which blinks on key on) to the CEL light and call it a day.

So close to finished, new top, wheels, brakes, suspension, interior, lights.. just needs some paint and have to sort out the AC.

Thanks wmburns. Using pinpoint test A, I found a wire that had been damaged by the previous owner. Looks like he tried to T something into it. Problem solved!
