70 Yenko Electrical issues--Help!!

[rcc]

I separated the two parts of the wring harness that is mounted to the steering column.. I used a little fine grit sandpaper on the exposed metal tangs and then sprayed both parts with electrical cleaner. Same problem. No green indicator lights on the instrument cluster for either turn signal indicators or ER flashers.

Next, when I am not so sore from lying upside down, under the dash, for prolonged periods of time, I will check the indicator light bulbs themselves.

Sure appreciate the help.
