No brake lights, no turn signals, no hazard lights

I have the sequential setup for tail and brake lights that has been in the car for at least 8 years with a Raxiom flasher.

Yesterday I noticed two brake light bulbs out on the passenger side while the hazard lights were flashing. This morning I was going to replace the bulbs but they were all working again. So I thought I would replace bulbs anyway. While I was changing bulbs I thought I would try a 3157 LED bulb I had left over from another Mustang. I plugged it in the socket and it worked but was very dim. I pulled the bulb and flipped the terminals around and it was still dim. So I put the regular 3157 bulbs in and nothing. No brake lights, no hazard lights, and no turn signals front or rear. The Third brake light IS working.

I've checked fuses 13, 18, and 41 plus a few random fuses too. I swapped out the Raxiom flasher for an original style flasher. The original flashers are supposed to work with sequential lights but will flash faster. Still no success.

What am I missing? I checked the bulbs with an Ohm meter and they are good. Any ideas on what to check next? Thanks!

Update:


After checking the multi-switch, brake light switch and various tests I un-installed the sequential wiring harness and installed the original Ford tail light harness. Installed new flasher and rechecked fuses. This solved my problem. I assume trying the LED light bulb in the sequential harness must have overloaded and shorted something out.
