Morning,
I need to replace a headlight switch in my 65 Plymouth Satellite. I see that there are remakes for this unit with two different ceramic rheostat sizes,1 1/4" and 1 5/8" ceramic insulated rheostat. Many have the 8th terminal coming out the back on the bottom of the switch and a few without. I installed one with the 1 1/4" rheostat and 8th terminal but the lights in the instrumentation are dim except for the radio. My questions are this, does the rheostat determine the brightness of the dash lights and should I use only a switch with the 7 terminals? The unit i removed, which I have attached pictures of has a 1 5/8" ceramic rheostat but the part number on the bottom does not seem to exist. Up for any guidance, and thanks in advance.
