First off thanks in adance for the help.

I'm trying to install a Galls Street Thunder siren controller in a 2008 f-150.

I need a wiring diagram or some info to help me out on this.

The wires I need to locate are:

horn wire
park light or dash backlight wire
wire that gets hot when iginition is on
wire that will get hot when vehicle is put in park or door is opened. could even be dome light wire, but would prefer not. (park kill autoshutoff feature)
If anyone wants to look at the diagram for the unit it can be found here: http://www.galls.com/DOCUMENTS/SK125...ture_ST240.pdf

Thanks a bunch.

I found a brown wire that works for my park light/backlight.

The accessory wire isn't absoultely necessary.

I really need to locate the horn wire. As I understand it that wire activates the horn when grounded so it won't ever be hot in the cab. That's fine I can change a jumper to activate on ground. It makes it hard for stupid people like to me track down the wire though. I understand that after it goes through the relay then the wire is obviously hot to activate the horn, but I didn't want to have to go outside the cab to hook into the wire.

I need to locate the wire that tells the system the driver door is ajar. It can be a positive or negative wire it doesn't matter. I can make it work either way.

Thanks,
Deryk
