The printed circuit does have a coating. Was it coated well? Could it have deteriorated after all these years? We have to remember this car is almost a quarter century old. I would double check the wires going to the cluster, but the printed circuit is most likely the fault. For now that problem seems to be solved. If it happens again we will know it is not the printed circuit. As for the sequencer, last night I was going through the archives and discovered Thunder Chicken would know the most about this unit. He can figure that out if anyone can.

I actually used to make the sequencers (Thundercat Electronixx). There were a few different generations. The first generation used relays to carry the load and were sensitive to system voltage, which is why the engine had to be running to test and/or diagnose them. Later generations used all solid state electronics (electronixx?) and were more stable at low voltages (though I still recommend having the engine running during testing and adjustments simply because you're more likely to be using your turn signal while the car's running and it's best to have the sequencers adjusted to the most common operating conditions). I pulled the plug on the whole thing when I did the math and discovered that between the US dollar shiznitting the bed and eBay/PayPal/Post office fees going heavenward I was actually losing money on 'em. Plus I really, sincerely, with-every-ounce-of-blood-coursing-through-my-veins hated dealing with eBay people. Especially eBay Mustang people...

Ok, just dug up some more information that seems to point to the cluster being the issue (with the dash lights). It seems that the Cluster Illumination terminal and the Right Turn Indicator terminals in the cluster are right next to each other in the connector at the cluster (terminals 13 and 14, respectively, for the buttstuffogue/Sport cluster Vinnie has). This means that if the printed circuit board is slightly misaligned or if the connector is inserted slightly crooked a short could easily happen between these two terminals.

UPDATE to the UPDATE>>>> .Before I read the last few posts since 3:30 today, I pulled the seats and console after work. I looked under the carpet on the driver side, and there was a green wire with a yellow stripe (in a bundle of wires). It was melted. i followed the wire from the driver side kick panel, under the driver seat, over the tranny tunnel, under the passenger seat and up past the passenger side kick panel. I have no idea what the wire is for, or where it ends up or comes from, but I replaced the damaged area, and the rear lights are fine again on the driver side. The green signal lights on the dash are fine, the brake lights are fine, and the lights (all 6) come on when I turn on the headlights. The dash is not blinking anymore. I now, just don't have my outer two passenger tail lights in braking, emergency flashers, or signal lights. Only with the headlights on.. The driver side lights sequence as they should.

Where is terminal 13 and 14 on the cluster in the back? I didn't see any more damage. I can pull the cluster tomorrow to re-re-check.

the green wire is the ground to the trunk, and fuel pump I believe... I think I had to splice that one for the mass air

I think this MAY be a different wire. I have nothing to base that opinion on other than the fuel pump and trunk stuff (trunk popper and light) all work great.

This is a skinny little, pea  green wire with a yellow stripe. About 18 inches were damaged. Now repaired. That is, unless there's more under the dash that needs fixing. I have no idea where it goes.

Thanks. I'm off work and should be around here. I think there was a dark green wire as well in that bundle.

Thanks Tom. I'll be around here most of the day today. The wire is in a bundle that starts from the driver side kick panel and goes along the floor, then under the driver seat, over the tranny hump, under the passenger seat, and back up the passenger side kick panel, and I'm guessing, under the dash.

On the other hand, it could start on the passenger side and go the other direction depending on how you look at it. I started on the driver side, so, that's where it started for me.

Sounds like you've got some progress, Vinnie. You definitely have it on the run, now.
