Just thought I would save some of ya'll some time. I just installed an Electric Brake controller on my '08 Hemi.
When you have to splice into the brake light switch, the wire you need is the White with Orange wire.
I used this one and it worked great. It took me about 45 min to find which wire to use.
I hope this help.

You didn't have a plug for the controller under tha dash?

No. The truck did not come with the Trailer Towing Package. I have learned over the years that it is easier to just install this stuff myself. It save's a few dollars also.
I did manage to talk the Dealer out of a new reciever hitch though. I just had to wire in the 7 Way plug and install the brake controller. It wasn't that bad.

yeah man her 03 had a plug and a pigtail just plug in and wire to controler, what da shi#$ did they do to the 08's man.?

My dealer provided me with a pigtail to plug into the existing wiring under the dash when I purchased my "08".

Some have them and some dont, the wires for some of the ones with the pigtail are only enought to find behind the frong fender splash pannel, the wires dont always run all the way back so you will be searching forever trying to find the wires in the rear of the truck, they are not there most of the time unless you have the tow package, even then most stop around the rear axle area in the main harness drivers side. I worked at a trailer place for 4 yrs as a sales manager so pretty savy on those. Instead of putting the controllers on the bottom of the dash the pocket in the dash under the radio works great for a custom instal location!
