First Post - Keyed Power

Hi All,

I've been lurking here for quite a while, gathering tons of useful info, and now I have a question.

I have a 2008 F-250 Supercab, Gas Engine.

I am hooking up a plow and need a keyed power source. Searches here describe a blue / white wire in the steering column or under the instrument cluster. Well, try and try again, I can't seem to find this wire. Does anyone have any suggestions regarding this or any other source of power?

You can use the radio to trip a relay. Or you can use a meter to find the wire under the dash.

Thanks for the reply ReAX,

I can always tap into the radio circuit but I was hoping to use the dedicated wire that Ford supplied for this purpose. I believe this may be a new feature on the 08 models.

Has anyone else had luck finding this wire?

I'm guessing you don't have the upfitter switches? Those are only powered when the key is on. Might be something to look into.

They usually zip tie them in place up a ways kind of behind the OBDII connection plug.

On pre 08 trucks the white/blue wire is basically over the gas pedal. I would guess that they moved it on the 08's though.

Sounds like I'm going to have the dash apart again this weekend.
