Ignition source for boost gauge light 98 v70 t5  Topic is solved

Post by turtle1615 » Fri Sep 22, 2017 3:00 pm

I'm installing a Bosch boost gauge and need to find a 12v ignition wire but don't have access to a wiring diagram any help? Can be for headlights or just plain key on voltage. Would I be able to tap into the CD player wiring? it's aftermarket.

You really have a couple options here.

You could use the dimmer line that comes out of the back of the dimmer switch. You could use a line from the radio.


Wisdom requires knowledge as a prerequisite, but knowledge can be developed due to a lack of wisdom.
In order to learn how to fix something, you must first learn how to break it.

You can access the dimmer's output from accessory connector.
Read through this post and you should find all that you need:

The magic color for dimmer illumination is PINK.
