I have an 05 F250 SD CC SB 4x4 6.0L. There are 4 wires on the drivers side under the hood just above the master cylinder sticking out of the factory harness which look like they may be used for an alarm system or something. They are about 14 gauge various colors. The dealer says all trucks have them but can't tell me what they are for. Anyone else know what they are?
Thanks

Colors are... Blue, White, Red, black... 'Customer Access'... Firewall 'pass through' wires for accessories/add ins.. There's a matching set under the dash/fuse panel area....

 

Thanks once again Hayapower....
