Yes! Please do it...don't want them on all the time just when I want them, the PIAA Switch has to be cockpit mounted somewhere...it would be nice to have an alternative way of turning them on. I do like the lighted PIAA switch to tell the user the lights are on....
Let us know when you have it done and post a pic..
Are talking about something that will let you select between "on with key" or "high beam only". Depending on the type of road and traffic condition having both options may be helpful.
I don't think an adapter is required if it wll be permamnetly wired as one or the other. Currently you just attach the PIAA tigger to the ACC terminal or tap into the Hi-Beam relay wire under the seat.
