green182 Posted April 30, 2009 Report Share Posted April 30, 2009 Hello, 2005 Ford F150 Supercrew 4x4 I just recently got my new F90 installed at the dealership and uploaded the Cmh928 4.5.09 mod Now I am trying to ground this parking break wire and can't find it? What color is it and where should it be located? is this the only step I lack in having access to the parking break mod? thanks for all your help! Quote Link to post Share on other sites
lludacrisboy Posted April 30, 2009 Report Share Posted April 30, 2009 The Parking brake wire is a light green Color wire and it has a label on it that says parking brake. That is what needs to be grounded and it can be grounded to anything that is metal that will support a ground. Quote Link to post Share on other sites
CatchMeIfYouCan631 Posted April 30, 2009 Report Share Posted April 30, 2009 Keep in mind that if you're attempting the bypass, you need to also relocate the yellow/black wire (on connector 1, same as the AV in's and out's) up 1, and over 3 between 2 black wires, and ground that as well. If you really mean tapping into the vehicle parking brake, then that's not grounding, but the vehicle's wire will be connected to the actual brake itself. Quote Link to post Share on other sites

There is no need for the OP to move and ground the mute wire. He has done the Cmh928 4.5.09 mod. It includes the software bypass. OP: Be sure to cut or disconnect the green parking brake wire from any truck wiring before you ground it [the green wire from the AVIC]. Otherwise, you would get a constant parking brake on warning on the dash. Quote Link to post Share on other sites

1loudls Posted May 4, 2009 Report Share Posted May 4, 2009 hey does anyone know what is better bypass module or ground the parking brake? just grounding the parking brake wire doesn't work, you need to do one of the parking brake bypasses, either hardware or software Quote Link to post Share on other sites
