Wiper and headlight questions for '68

Hey everyone,

I recently finished a rebuild on a '68 in which I rewired the car using American Autowire's kit. I have a couple questions after the job is done...

1) Can someone explain the two settings on the wiper switch? I'm assuming there's no delay and it's just high-low, but mine seems to wipe intermittently. I'm wondering if the switch is bad or if I just misunderstand how it's supposed to work.
2) This is a really dumb question and one I should have gotten answered before I wired the car, but are the high beams supposed to be on the inside or the outside? I left enough slack in the wires to switch them, or at least I intended to.


Thanks in advance for any assistance!!

Re: Wiper and headlight questions for '68

Wipers are 2 speed, no delay. So they should wipe at slow steady pace setting 1 and much faster on setting 2.

Headlights. Low beams on outside. When switched to high beams, all 4 should illuminate.

Good luck!

Wow, you just cleared up such a misconception I had by adding on the part about when all four should illuminate. I was thinking this was like a modern car where all lights were on when you had low-beams and the high-beams would end up with just 2 lights. So, not only do I have my low beams on the inside, I have been driving around with the high beams on all the time (aimed down like low beams, though). And, this left me with two confusing situations: The red light was on in the dash all the time, and the "high beams" (actually, the low beams) would basically point at the ground. My expectation of how this would work was 100% backwards!

I guess the wiper switch is also an issue because it's intermittently working.

Thanks for the help!!!

Re: Wiper and headlight questions for '68

To add to the confusion, and hopefully you already got this right; ‘68 had different wiper motors and switches depending on whether your car has hidden wipers or not.

Re: Wiper and headlight questions for '68

The power source for your wipers goes directly from the fuse to the wiper motor and does not run through the switch. The switch needs to be grounded to the dash and the switch itself closes the ground circuit for each speed and park cycle. The ignition switch must be on to show power to the fuse and wiper motor.

I might add that the switch for the hidden wipers is usually higher priced than the standard wiper switch.
