Headlight operation 72 US Sprint

[tvacc]

Hello all,
Long time since I drove or owned a Sprint. About 25 years. I just got my Sprint and am fixing a few things. I am installing the Spyder electrical headlight pod system. The instructions say to put an on/off switch where the vacuum switch is on the dash. So I am about ready to put power to the whole thing and I removed the under dash trim. I just pulled the vacuum switch and I see there are other wired going to it. When I pull it, I hear a click, maybe the relays for the lights?

What are the two "light" switches supposed to do? I see the right hand one turns on the parking or running lights. I cant see if the headlights are coming on when I pull the vacuum switch as the pods are down.

And I have no one here to raise them to check. So I need someone that has a US Sprint to tell me.

If the vacuum switch also operates the headlights, I may have to just put the on/off for the headlight pods in the glove box. Anyone done this conversion? Anyone have any ideas?

Ok, had someone help me determine that the vacuum switches on the headlights.

So what do I do? How do I raise the headlight pods? What have others done? Switch in the glove box? Under the dash somewhere? Open to ideas.

Tony, if you still have the stock wiring, here's a pic of the Federal Sprint wiring for the headlights (courtesy of
Phil Harrison). In stock form, the pull switch does two functions: releases vacuum and electrically
switches on the headlights

Also, I attached a picture of the oem arrangement. Shown is the backside of the plate where the two
microswitchs attach and are activated by a cam on the vacuum part of the switch. Hopefully, at least the
wire colors can get you pointed in the right direction.

Edit: I also attached a pic of how the two micro switches are attached, showing the 'on/off' orientation. Ignore
the vacuum switch itself. This is my adaption of a Corvette vacuum switch with the micro switches attached.

Not sure if the pdf was attached Greg... here's the original post with the file - viewtopic.php?f=38&t=30133
