Hi guy! I have a DS Signal issue.

I'm using the RF harness as well as one of the last Russ Thompson Turn Signals. Using stalk for horn only. Headlights and running lights working find. All blinkers and hazard lights are working fine except the DS. Turn signal and hazard dash lights are working correctly.

I'm not getting any power to the DS Dark Green LS Turn Signal wire for both hazard or left turn signal. I read on the forum that one person had a wire crossed in one of the RF connectors that caused the some issue and he had to depin and switch them.

My current plan to trace the issue is check the connections at the Hazzard switch and the Russ Thompson turn signal. Body is on, so getting to the connections might be fun! lol

Any other areas I should be looking?

Thanks in advance!

You should be able to see the connectors through the access panel on the driver foot box top. Maybe it got crossed with the green fan wire.

Thanks Michael! That was also on my list of what to check, but the fan seems to be working fine. If all else fails, I might try running a new signal wire to the light. I think the wire would start off after the turn signal/dash light branch? At least until I remove body for paint.

If you haven't done so already - Run a separate loose wire from your battery positive directly to your light. If it works - you have a short somewhere in the wire.

I had the same issue. Check where the harness in the car plugs into the front harness. Look at the wire colors on both harnesses. I had one color wire on the cockpit harness, but two wires switched on the front harness. The colors are supposed to be the same, coming in - going out, as your looking at the plug connection. Easy enough to remove the wires with a small screw driver and switch to correct.
