Idiot Temp Light and Idiot Brake Light Not Working

[gschroeder]

I have a freshly restored 1970 CST10. Unfortunately the idiot temp light and idiot brake light will not illuminate while cranking the engine. I have confirmed the bulbs are good by switching them with another light on the dash. By the way, I have the deluxe dash with all the gauges and tach. I tried gounding out the brake light at the master cylinder, and grounding out the temp light at the temp sensor on engine, but still cannot get either to illuminate manually. Any suggestions on how to trouble shoot this is appreciated. I hate these electrical gremlins, and hope someone can point me in the right direction. Thank you
