Hello, I am a WRX newbie and just bought an 07 WRX. I used to build SR20's and N/A Honda's, but the WRX is a whole new experience for me.
I am having trouble with an electronic boost gauge by Defi (52mm Blue Racer series). I T-connected the boost sensor with the FPR vacuum line and into the gauge, which seems fine as the gauge reads 12-13 psi (stock) under WOT.
However, I have an ATI triple gauge pod to replace the clock and so I decided to wire the gauge into the clock wires. I had to cut them to do so, and now I have a working boost gauge but the radio and interior dome light won't come on! I wired it as follows:
Defi red wire to car's red/white stripe
Defi orange wire to car's yellow/blue wire
Defi black to car's black
Where does the defi white wire go?? Does this have something to do with the radio not working? Sorry if this sounds dumb, but I am new to this wiring.
