jaedee Posted April 15, 2008 Report Share Posted April 15, 2008 sounds to me like something is wrong with the bypass. Quote Link to post Share on other sites
Sprawl Posted April 15, 2008 Report Share Posted April 15, 2008 if you did the bypass correctly, i dont believe you would have plugged into the speed sensor with the speed sensor plugged in, it'll dissable the screen. when you do the bypass you have to ground the speed sensor Quote Link to post Share on other sites
kaplan_reject Posted April 15, 2008 Report Share Posted April 15, 2008 Nope, I got the VSS hooked up on mine, it has no effect on the bypass. Double check your work and make sure all connections are right and secure, if you think they are right, check again, it will work. P.S. I was having trouble with the illumination with my PAC harness and would have bet my next paycheck that I had a good connection. Finally tore the dash back down and re-did the butt connector and guess what.... Quote Link to post Share on other sites
06f150stx Posted April 15, 2008 Author Report Share Posted April 15, 2008 i did what everyone said to do. moved the yellow/black wire to the slot right above its orriginal spot and ground it along with the green wire for P-Brake. but i will check again for bad connection. i know when i start my truck up, its says that the P-Brake incorrectly wired.

kaplan_reject Posted April 15, 2008 Report Share Posted April 15, 2008 When you ground the parking brake wire, did you ground it to the parking brake or to another ground (any ground will do). Cause if you grounded it to the parking brake then you would have to have the brake on for it to work. All you have to do is ground it to the same ground as the avic is grounded to in the wiring harness and it will work fine. Quote Link to post Share on other sites
06f150stx Posted April 15, 2008 Author Report Share Posted April 15, 2008 i have it grouded to the metal frame thats under the dash alog with the yellow/black wire. Quote Link to post Share on other sites
kaplan_reject Posted April 15, 2008 Report Share Posted April 15, 2008 That should work fine, Just make sure that the ground is good and the connection secure. I find that its easier just to make a ground bundle when doing an install for all the grounds to a factory chassis ground, ie... hook up the avic, bypass, bluetooth and satellite radio grounds all together and them connecting them into the factory ground in the wiring harness. Just check and make sure that the pin is secure in the accesory connector, some seem to have trouble with that Quote Link to post Share on other sites
06f150stx Posted April 15, 2008 Author Report Share Posted April 15, 2008 yea, i did have a problem getting it back into the connector. i'll be geting off of work here in about 30 min. so i'll check that when i get home. now, the ground for the avic, i used the one that was in the factory harness.

kaplan_reject Posted April 15, 2008 Report Share Posted April 15, 2008 just take the brake wire and the bypassed mute wire and splice them into the factory ground where you grounded the avic, that would work just fine. Quote Link to post Share on other sites
