Strange Blinker problems- 04 TR4 Limited V8

I have a 2004 Limited V8. I am having the following issues...

When I turn my left turn signal on- the front works fine. In the rear both(right and left) turn signals flash. Also the R(for reverse) in the dash flashes. I also notice a clicking noise underneath the vehicle around the transmission. If I apply my brakes the clicking noise stops.

When I turn the right turn signal on- the front works fine. In the rear the right reverse light flashes, not the turn signal.

When I put the vehicle in reverse- the reverse lights don't work. Both rear turn signals light up, faintly. Also the left turn signal arrow on the dash lights up.

I do have the aftermarket Depo LED taillights but I've had them installed for a while before this problem happened. So I don't think that is the issue.

I need help!!! THANKS!!!

You most likely have a damaged (moisture) harness connector or short in the wire harness to one or both of the tail lights. Another possibility could be the wiring harness for the towing trailer connector (if you have one). In either case, I doubt anyone will be able to diagnose it online, without being able to visually inspect it. You will have to do a visual inspection of these areas yourself, or have a shop do it for you.

Well it turns out that it was those Depo taillights. The left one had a bad ground(or neutral) wire. It wasn't making contact on one of the connectors inside the light. Easy fix. Hard to believe that was causing all those problems. Nice to have reverse lights and blinkers again!!!
