rittenrotton 4 Report post Posted April 21, 2020 Need some help...i rewired my 1970 coupe with the American Autowire kit about a year ago and recently replaced my turn signal switch with a new one from CJ pony parts; the problem is that the wire colors on the new turn signal switch don't match the OEM turn signal switch. (Yes, it is the correct switch for my 70, non tilt steering wheel). Everything works with the exception of the blinkers (but hazzards work). The other issue I'm experiencing is a short with the brake lights. With the turn signal switch installed and steering wheel removed, the brake lights work perfect. But when I install/attach the steering wheel, the brake lights short out. I can actually see the Sparks whenever I rotate the steering wheel. Any help solving these issues would be greatly appreciated! Quote Share this post Link to post Share on other sites
aslanefe 333 Report post Posted April 21, 2020 Blinkers and brake lights are controlled by the cam on the left, and hazard switch is seperate (on the right). Repop switches are not known to be of decent quality, looks like a short or no contact issue under the cam. Can you see where the spark is coming from? You may also have a pinched wire.

Midlife 814 Report post Posted April 21, 2020 On earlier model Mustangs, the turn signal switch devices have rivit heads on the back of the TS switch, and these can contact the steering column (ground), shorting everything out. I always advise folks to put a piece of electrical tape over anything metallic on the back sides of the TS switch. Quote Share this post Link to post Share on other sites

I can't really see the exact spot as the steering wheel blocks my view but it looks like it coming from the area near the Hazzard switch. Quote Share this post Link to post Share on other sites

I did but I feel like I need a wiring diagram for the ts to know exactly which wire is for which. I figured out the wires/connections for both horn wires, brake lights, Hazzard switch but it's the rest that I'm kind of lost. I tried guessing based on the wire colors on the camber of the ts switch but I obviously didn't get it right. Quote Share this post Link to post Share on other sites

If you can't find a wiring diagram in a day or two message me and I will remove the switch and try to get you which wire goes into which pin on the connector.

Midlife 814 Report post Posted April 22, 2020 Looking at the underdash harness side of the turn signal switch connector, with it concave down, the top row left to right is: blue (turn signal flasher) orange/blue (rear right turn signal) green/red (rear left turn signal) white/red (e-flasher signal) yellow (horn input On the lower row, left to right: black (key reminder) green (brake signal) green/white (front left turn signal) white/blue (front right turn signal) blue/yellow (horn output) Quote Share this post Link to post Share on other sites

rittenrotton 4 Report post Posted April 22, 2020 So I feel like a bit of a fool. How's your day going in Tuesday / I realize that I had a bad flasher and I didn't have the correct fuse installed. But thank you all for your help and suggestions, I really appreciate it Quote Share this post Link to post Share on other sites
