All four turn signals flash at once

I have a 79 kz 750. Im trying to replace my stock turn signals with aftermarket NON led mini lights. I hooked everything up like it was when the stock lights were on. Changed to an electronic flasher also. All four light turn on but when I go to use my turn signal all four turn signal lights and brake light flash at the same time. The only thing different with my new turn signals is the stock signals in the back were a single wire and my new lights for the rear have two wires. I'm stumped

single wire lights ground to frame through the housing, so depending on how you have those hooked up, I would check to make sure you have a clean, well-contacting ground on the frame near the lights. Since that was how you were originally set up, try grounding the 2nd wire to the frame (assuming you tied both back into the harness).

I wonder if you got the turn signals hooked up like emergency flashers? Some bikes had that option to make all the turn signals flash at once.

im not sure. im going to try to hook up my stock lights back up and then just change one light at a time and see if i can figure it out

I just did this same thing lastweek. i had the same problem!!! You probably have 3 wires to each light? one of them (blue on mine) doesn't get hooked up it closes the circuit and causes all to go at the same time. only use two wires... power to power, ground to ground and you're good to go as long as you have that electronic flasher you're set!!
