: Another hight idle/LB7-ZF question

in my search for a 12v power source to power my high idle without using a switch, I found a purple wire on my brake switch that's hot but doesn't have power when I step on the brake.

Does anyone know what this wire is for and would there be a problem using it?

Tony, I tried the parking brake circuit but even after 25 years the parking brake only closes the ground and I really don't want to mess with a relay :rolleyes:

Why is everything I do never easy? :o:
thanks!
