66 Nova Wiring diagram?

Does anyone have a wiring diagram on their PC that they can send me? I'm having some trouble with the brake light on the passenger side of the vehicle.
The tail lights both work, both signals work but the brake light on the passenger side doesn't light. The dark green wire shows current with tail lights and turn signal but nothing with brakes applied. Though the yellow wire shows current for turn/tail lights and brake.
The switch on the pedal reads closed when the pedal is pressed so that's working.

Any ideas or a diagram?

Hmm.. dont' the tail lights require ground? I'll check it though. It's been years since I worked on this stuff! Just picked this car up last Saturday. Thanks for the tip I'll check the ground.

Yes Denny, all filiments are good. The right side does seem to flash a tad bit faster.

Are you agreeing with the bad ground statement or are you suggesting it was a laughable answer?
I do have juice on the wires, juice on yellow for turn, tail and brake (rear right) but only juice on turn and tail for dark green (rear left) no juice for brake.

Both brake lights are on the same fuse though, right? So if one works, and the other doesn't then odds are the fuse is good. I think. ;)
I'll double check the ground but I pulled the steering wheel off and all looked good on the signal switch.

Yep.. that's right. I'll check the grounding tonight to see how it's grounding. I guess I didn't even think to look at that, I just assumed there was a problem elsewhere with the positive side.
