Got a set of these , got most of it figured out except for the switch control positive wire. Where does this hook up to?? The install states that it must be one that is only powered when the high beams are on. Soooo I cant hook it up the low side? And where do I find the wire for this? :shrug::shrug::shrug: HELP
Give the file in the link below time to load. See the wiring diagram. I hooked the light gauge
white switch controller wire to the + connector on the back of my right high beam connector so the PIAA lights only work with the high beams. You only need to remove the right storage pocket to do this. Do not attempt if you are not good at soldering. It helps to be limber like a reptile :joke:.
The wire should be supported with tape to isolate it from vibration.
You may also hook it to the high beam + wire in the dimmer switch or back at the relay box + input.
If you don't care and want it to function with either high or low beams, hook the white wire from the switch to any + switched wire. The white switching power draw is minimal.
I have some circuits that allow only operation on low beams but can't draw circuits that well. (Our WALDO is a great artist and a great circuit designer :nojoke

.
I did not like the PIAA switch supplied so I made my own circuit switch.
I have also found a source for the PIAA relays that are tough to find :thumbup:.
