So I bought new led turn signals and a badlands shut off III module (it's a timer that let's you push the button and the signals blink for 11 secs then shut off). Reason being, my '90 sporty doesn't have self canceling signals.

Anyway, wired it up and now when I push either turn signal button, all four of them blink instead of just the left or right side. I asked badlands tech support but they didn't give me more info other than 'power should go to the switch, then when pressed the power will continue to wires going to the module.' Which doesn't tell me why all 4 blink together...

Here's the wiring diagram for the module http://www.namzcustomcycleproducts.com/images/ATS-03.pdf

Heres how I wired it
[1] Violet wire from module to Violet wire coming out of left turn signal button
[2] Brown wire from module to Brown wire coming out of right turn signal button
[3] Red wire from module to 15-amp breaker for the accessory circuit
[4] Grey wire from module to Grey wire coming out of left turn signal
[5] Yellow wire from module to Grey wire coming out of right turn signal
[6] Black wire from module to negative side of battery

Do you guys have any tips on what to change on my wiring setup? Btw, can't find a wiring diagram for my bike but the turn signal circuit is similar to most Harley's from ~75-95 years

 

Something to try. Put the bulbs back in and try it. Sometimes the factory switches the wires. LEDs have to be wired correctly, incandescent does not matter. I have 2012 and had to splice and switch mine for LEDs to work. Black to purple. This simple test will tell you.
