Sequential Tail Light Issue

Ok guys I've got an issue with my sequential tail lights on my 06 mustang. I bought the plug and play kit and the bulbs aren't working properly on one side. When I turn the running lights on they all light up. However, if I hit the brakes or turn on my left turn signal the 2 outermost bulbs will not light up or flash. I've switched the bulbs and it's still isn't fixed. Any ideas?

Double-check your connections, make sure they are clean. Use silicone spray to lube/ clean them. Make sure your bulbs are the correct type and wattage.

Check the circuit board on the harness. When I had my 05 with sequential tail lights, one of the wires was run over the board and fried it. I bought it from one of the big Mustang parts suppliers but since I was out of warranty I was out of luck. I ended up going back to the stock harness.

I had the same problem with my plug and play sequential harness on my 2005 Mustang. I went to Home Depot and bought CRC contact cleaner, sprayed it in the connectors one night and left it alone like it said till the morning. Never had the problem again, except now i have a nearly full can of contact cleaner that I don't know what to do with.

Did you spray it into the bulb sockets? Or the connection for the entire tail light harness? I think I'll try this. Does it need to sit overnight after I spray it?

Both actually! I figured while I was in there, I would knock out all possible options since it honestly took maybe 2-3 minutes, and I recommend doing the same thing so that you don't have to go back and spray whichever one you skipped. Overnight? Not necessarily. I think the can says like 4-6 hours of letting it sit without use, so I chose to do it overnight since I knew if I was going to sleep, I wouldn't be using my car. It's all up to you, as long as you leave it alone for the recommended amount of time.
