Hi All,
Running into some issues while installing the AAW harness. They all feel related. I've rechecked all connections and grounds several times and everything looks good. Any tips on troubleshooting? Issues listed below...

1. With the left blinker on, dash lights turn on and blink
2. With the headlights on, left blinker does not work (right blinker does). Can't hear the relay clicking, just get nothing. With the exception of issue #1, the left blinker otherwise works when the headlights are off.
3. Pressing brake turns dash lights on.

Thanks in advance for any advice!

For '68 there are two mistakes in the AAW instructions for the turn signals at the lights. Blue wire to blue wire is correct, but the tan wire should be a hard ground, and it's the black wire that should connect to the brown. I had the same problem as you, I think, and called AAW and spoke to Ray. He told me about this, I made the changes, and suddenly like magic everything worked. :yoho:

Thanks for the response. Are you referring to the wires coming from the front turn signals? I actually have those setup as you described. Tan wire from back of turn signal is grounded and blue and black wires go to a connector that connects to the brown/blue wires in the harness.

Hmm. It would seem that AAW has updated their instructions since I did mine. I'd call AAW Tech Support first thing tomorrow. The one time I called and left a detailed message I got a call back that same afternoon and we figured it out. I hope you have the same good fortune. :thumbsup:

Yeah that’s exactly what I’ll do tomorrow. Thanks for the help!

Are all of the lights mounted to the body or just hanging loose for testing? The lights ground through the buckets to the body, so if they are just hanging loose, or body work is preventing a good ground, you can see the dash lights coming on with the blinkers/brakes.

Hmm... all mounted to the body. I do have a fiberglass nose as well as Shelby lights in a fiberglass rear panel. I wonder if I need to add some grounds back to some actual metal.

I had to add ground straps from the taillight buckets to the body.
