Weird electrical problem

I just bought my '03 DSG Mach a couple weeks ago and now I've got a weird issue.

The ABS light and trac control light have been on since I bought the car but the salesman said it was because the previous owner used a tuner to disable to the TC...not so sure about that because of the ABS light but whatever.

Last Saturday morning I went out for a drive, no issues. A couple hours later my wife and I were about to go to a pool party when the car wouldn't start. I pulled the key out of the ignition and noticed that the odometer stayed on but only displayed dashes, the Service Engine Soon, ABS and TC lights were staying on.

I tried starting the car again but couldn't hear the fuel pump priming so I figured maybe something was wrong with the key/PATS. Next up was to start pulling fuses. None were fried but I came across fuse number five which is for the instrument cluster, traction control switch. Pulled that fused, all the lights turned off and the car "magically" started up. The gauges didn't fire up immediately but start working about 15 seconds after cranking.

I put the fuse back in and the same lights come back on but at least the car starts. I've been driving it without the fuse in because I don't want to drain the battery.

Any ideas? I can't think of anything that could be causing this.

Edit: Forgot to mention that with fuse number 5 in place, the THEFT light doesn't flash when the key is out of the ignition. Removal of the fuse and that light starts functioning normal.

Sure sounds like a bad ignition switch to me. The clue is the cluster stays on even after the key has been removed.

Replaced the ignition switch and it did not resolve the issue. Possibly the cylinder? This is pretty damn frustrating!

Is there a way to pull ABS codes through the dash display like with the ECC codes? I heard you can get DTC codes but don't know how.

Instead of pulling the instrument cluster fuse, I tried some others and found that pulling the fuse for ABS has the same effect without losing the idiot lights and causing the gauges to delay for several seconds on start.

My odometer goes on and off? - Ford Mustang Forums

However, I'm more the test first and then replace kind of guy. IE work through the wiring diagrams making key tests and replace the parts that are actually broken.

Do you have a full set of Ford factory wiring diagrams and service manual? These would be a huge help on a problem like this.

Do you know if the diagrams are available online or would I need to buy something like a Haynes manual?
