I have been working on the install of my STS, Well really everything but the Turbo (Should be here today). The installation of my gauges is pretty much wrapped up. But I'm having a hard time finding a good "Key on" power supply for all the new equipment. Right now I got an inline fuse supply line from an unused relay under the hood.
Anyone found a good place to tap in for "key on" power under the dash and under the hood??
I still need to power up the Wide band, and Map sensors.
And does anyone know the voltage requirements for the STS supplied boost controller?
Thanks.
So many wire to run

 

Best place I found was to tap into the wires coming from the ignition switch on the stering colum. I wiil see if I can get you the color I used.

 

The steering column or the backlight supply wires to the AC panel or stereo. Easy enough to get to.....
