At the Miata Club Holiday Hoe-down on Saturday I managed to sell a couple of Lynn’s Brake Lite Blinkers. One fellow couldn’t get his to work no way, no how (even blew a couple of fuses trying.) He came over this evening and we tried a couple of other units and had the same results. I told him to let me try some on my car (haven’t done this mod yet) and if I got some to work I would write down how I did it and we would do it on his car.
My first attempt was like he tried, green as ground (so the black blinker wire hooked to them) the yellow to the light and the red to the wiring harness, it didn’t work. I tried swapping the red and the black wires as per instructions and it still didn’t work.
Black is ground on my car and probably will be on his car too. When I hooked the black wire from the blinker to my black wires in the car with the yellow wire to the light and the red to the wiring harness they all work as advertised.
Don’t ask me to explain why this worked because I can’t (and I was an electronics technician in the Navy for 10 years) because the second set up is the same as the first setup with swapped wires. So if that didn’t work, this second option shouldn’t have either – but it did.
Mine is up and running, hopefully tomorrow so will his.
