Need Some Help With Sequential Tail Light Issues...

[Jnicho]

I have LED tail light bulbs and purchased the Universal LED Sequential Kit below.

Seemed pretty straight forward. One set of wires for input to the module and 3 sets of outputs, one for each bulb...one module for each side of coarse. There is a neg ground, a pos running light wire and a pos brake/turn wire. The input side also has a wire that is to be hooked directly to the brake light switch. I cut, spliced and got everything wired up and hit the hazard light switch. Both sides sequence just as expected. Turn on the headlights and the tails light up just like normal...hit the brake pedal and have brake lights.

So far so good right? Here is where things get weird. Turn on the ignition to the run position. Left and right turn signals work sequentially just as they should. Hit the brake pedal and whoa, they flash like hazards. Even more bizarre, turn on the headlights and they flash like hazards. Turn off the key and they work fine again.

What in the world changes when the key is on that would do that? This is simple wiring...I've even rechecked my wiring to make sure I didn't do anything stupid...for crying out load it's 2 hot wires and a ground, LOL!

Any ideas???

First thing I would check is the ground..........the next thing I would look at would be if you crossed the constant power with the signal wire.

I rechecked everything yesterday...pretty sure no issues with wiring mistakes. As I mentioned there is only a ground and a hot for running lights and hot for stop/turn, so not too much I can jack up...and they work right with the key off. I don't think they would work right at all if I mis-wired something.

Move the ground to a different location (off the harness) and see what happens.

OK...I will try a chassis ground instead of just the harness and see what happens.

I'm guessing the module(s) is bad?

That's unlikely since it's happening with both sides.

Ya...both sides behave the same so I don't think it has anything to do with the modules being bad. Has to be something wiring related...I just don't get why turning the key on makes a difference.

It's hard telling. Chassis ground both of them and see what happens.

If they still do the same thing, we can rule that out the "bad ground" as a possible issue.

Gonna try that first. If that doesn't work I going to rewire it all and wire the grounds and tails by them selves then wire just the turns and stops with the modules and see what happens...keep trying various scenarios until I find one that works or I give up I guess, LOL!
