Boost Gauge Illumination Problem

[ERLoft]

So, installed a new Defi Racer boost gauge this weekend. Went pretty well - it was replacing a Prosport gauge, so it was pretty straightforward. However, same as my Prosport gauge, I wasn't able to find a wire that supplied +12v when the headlights/parking lights are on. Seems that the wires coming off the combination switch (light/turn signal stalk) are +12v when the lights are off, the go to +0v when they're on. I was able to find two wires that are +12v when the low beams are on, but they go to +0v when the high beams are on.

 

I know most of you have been able to use the clock illumination wire, but as I have a Spec B with nav, I don't have the clock. I would imagine that the wiring is still present though, so can someone post up a picture of what the connector to the back of the clock looks like so I can see if it's present in my car?

 

Alternately, if anyone knows of a specific wire that's +12v when the parking lights/low beams/high beams are on, I'd be happy to find it on my car!

 

Thanks!

C'mon now - no one has a picture of what the power connector for your clock/trip computer looks like?

Just use the power from the bulb that lights the roof of the cubby hole. It only comes on when the light are turned on.

I don't have a cubby. Spec B's have the satnav systems instead. That's why I'm asking for help...

How about the wire to the ring on the cig. lighter?

Got a boost gauge yesterday, it came with a connector from the Dimming switch to the left of the steering wheel. Maybe you can jump it from there.

Might have been a thought. I ended up removing the nav screen and using my multimeter to figure out which wire controlled the dimming there and tapped off of that. Works fine now.
