2008+ fog wiring diagram

RichM · 12-28-2010, 05:47 AM

Anyone have a picture of the lighting wiring diagram for the 2008+ Impreza?

I want to study the circuit to see if a pigtail (between the stalk switch and main harness) can be made that would allow the stock fog-lights to be turned on with the parking, low and high beams not just the low beams and keep the dash indicator light functional.

no one? bummer.

Paid the 35 bucks for a look at the wiring diagram. Can't be done with a pigtail at the switch stalk. But might be able to be done with a simple BIU (Body Integrated Unit) programing. Anyone have access to the Subaru programing options for the BIU? Anyone?

I've sent an email to Subaru asking if they will allow programing of the fogs to be active without the low beams only. It is not a Federal requirement and isn't a requirement in my state. I also think in some other markets it is possible to turn on the fogs without the low beams.

I wouldnt worry about messing with the BIU I would simply run power to the lights from the stalk switch wires. all it would take is some wire, some solder and a few diodes to control current.

Here is a good thread on how to by-pass the wires and get your fogs on at anytime. I hear the interior light for the highbeams turns off when you do this, but everything still works. It's something I've wanted to do for over a month now, but just haven't had the time.

I had the fogs in my '08 wired so they could be independently controlled via the stalk. I just ran a low current control wire from a switched 12v+ source to the wire going into the stalk, thereby bypassing the high beam switching, etc. The wiring was done in the column, under side just in front of the steering wheel.

I put it back to stock earlier this year though, as the OE fog lights suck and aren't worth the amperage penalty. I will be removing them completely in the spring and putting in the OE fillers that the 2.5i has when I get the RI light bar back on with Hella's.
