Good Morning everyone.

I've been trying to find a diagram of the circuit board for a 1973 Camaro with the standard gauge cluster, that has the bulb arrangement clearly spelled out. I've used the standard wiring diagram to trace the paths on an OER replacement circuit board, but I can't seem to locate where exactly the bulb from the wiper unit fits back into the cluster. Of course, I should have taken better notes when I disassembled the thing, but that's on me. Appreciate any help in advance!

Does your car have a bulb in the wiper switch or does it use a fiber optic feed from one of the cluster bulbs to illuminate it?

If it uses a bulb, it should have its own pigtail with a grey wire.

I believe the bulb runs directly from the wiper unit. I remember reading about the fiber optic feed on the 1973s in one of the stickies, but scratched my head since it didn't seem to apply to mine.

On the wiring schematic for the 1973 Camaro, there is a bulb labeled "BRT" among the illuminiation and turn signal bulbs in the middle of the circuit board layout. Any idea what that stands for, as Google has been no help.

I have a 73 and I remember it is fiber optic and it attaches in a hole near one of the bulbs on the side of the cluster carrier. which bulb I don't remember. Its been 2 or 3 years since I had mine apart. I'm having trouble remembering what I did last week anymore!

From a 1973 Chevrolet service manual. Mine is a Z28 with gauge cluster

Your welcome. Looked in my assembly manual and found this. It shows the fiber optic cable and where it goes. It is called a conductor assembly. number 4
