i need to know which wire and if its 12v(my multimeter broke) you know when u turn on the internal lights...and not the headlights....is that a 12 volt source and which wire is it.....i dont want my water/meth controller on all the time.

 

Iposted a pic of the wire a while back. Itwas in a "where to wire boost guage" thread. I have a multimeter if u need to borrow it

 

link me

 

If only you were a day earlier. I had my dash opened up to wire in my controller, and I had the multimeter out.

I skipped the inline fuse that was supplied and tapped into the 10A line that powers the heated mirrors (loc. 1 in fuse panel). Beyond that, I'll add an on/off switch when I pick a permanent location for the controller.

 

its cool...and the best place i could find was the same place jetta red put his....u have to drill a 1/4 hole and feed the wires through the back...plus u want the power to the controller on all the time and ready to start pumping when needed...esp if you tune for it
