i just finished setting up my w200. The only thing thats are these wires. I can't find them. Where are they located? Or is it easier to just order a PAC Tr-7? Also I have the metra kit from crutchfield and I can't close the door. Please help.

 

e-brake wire is black at the ebrake lever... pretty simple...

foot brake is blue in a four pin plug above the brake pedal....

the TR7 works nicely... cause you can watch video while you drive... otherwise you can wire up two switches to mimic the brake and ebrake... its up to you...

 

there are 2 blue wires in the four pin plug above the brake pedal. which one? Thanks

 

the bigger gauged one.... if i remember correctly... but test it just in case///
