I'm having trouble with the wiring on my profec 2 boost controller. i can't seem to find the color (positive) to power it. I found two that are red, but its constant so it stays on all the time even when the car is off. Does anyone know the color of the wire thats under the steering column that i need to hook it up to so its only on when the car is turned on?

 

anyone? it would help a lot so it doesn't drain my battery all the time.

 

I tapped into the 12v acc from the radio. Wire is Light Blue/White

 

if yours is the same version of the one I have the color coding is as follows. white and green go to the big box under the hood and black goes to ground and the red goes to a switched 12V source ie. like maczpayne said the radio switched source would work perfectly.

 

bring this back from the dead, the wire for the power connector on the boost controller is silver and the radio is copper, so i doesn't work. Anyone know where else or how i can connect it?

 

there shouldnt be a problem with the connection cables are cables. but in case there was a problem get an universal relay (4 pins NORMALLY OPEN) and run a cable from the battery or (constant power) to the relay and from the relay to the boost controller and connect the relay ground to the body or another ground. use a switched 12V source to activate the relay. but really i dont see why there would be a problem with connecting a cooper cable with a silver. I connected mine to the radio source and worked fine.
