I ordered a universal set of sequential tail light flashers for my project car, a 66 Mustang. They came with a very simple installation instructions, I followed to the letter starting on the passenger side tail light. Turned the ign on and flipped the blinker on and the sequential worked, however the driver side tail light also started blinking normally. That was wieid, so I hopped in the car to shut the blinker off and my dash lights were blinking too.

I hate electrical, I just don't get it. It's all the devil's magic.

Anyone here good with this sort of thing? This is just nothing but a headache for me.

I can't see what you did through this monitor, but it seems you got a wire or two crossed up. Wiring can be tricky at best, double check your installation instructions and the connections that you made. Nobody's perfect, you might have tapped a wire that you didn't mean to.

Automotive electrical diag pays my bills. You need a better ground more than likely. Post up a diagram do you have a multimeter?

Are the sequential lights LED by chance?
LED flashers require you to change the flasher relay to one that is compatible with LED flashers.

That and check your taillight grounds

To answer the questions posted: Nope, no LED's, just standard bulbs.
Hell no, no multimeter, wouldn't know what to do with it.
Wiring was easy, One wire to each bulb, I have 3 bulbs each side. One to ground and the last to hot. Easy as can be. Except it's me doing the work... I probably won't get to it again until the weekend.

Not sure how my weekend is going to play out just yet but I might be able to swing by with my meter and we could check it out.

Swap the sequenceal tail light flashers to the opposite sides wiring to be sure both work properly before over-thinking the problem.

You could have been sold a bad sequenceal unit.

Didn't consider that, that's true.
