I have a couple of electrical questions on a 71 Nova. First, the brake lights stay on most of the time. I put on a new switch but didn't help. The switch is adjusted as far as possible towards the pedal. The brake pedal spring brinthe pedal back just about all of the way. there may be about a 1/4" play in the pedal. The switch is bottomed out in the holder as far as possible. Any suggestions? Second, where is the horn relay suppose to be mounted on a 71. I have a drawing showing it near the radiator. Mine is on the firewall near the brake cylinder. Having problems with the horn all of the time. I replaced the relay but it is different than what was on the car and the new one has a bent tit that seems that it needs to be inserted in a hole somewhere.
