Can anyone tell me where to find the speed wire (and what color) so I can hook up my Pioneer AVIC-N3 gps navigation head unit? I also need to find the Hot side of the parking brake wire, I see that the parking brake is a negetive trip so I need to find the hot side of that switch. ( I know I could run a relay but if someone knows where the other wire is its a much cleaner install. Thanks for any help. I feel like I got a new toy but cant play with it till I get these wires located and Identified.[]

 

btw I have a 2005 ram q-cab
