I uninstalled a handfree phone system..took about stereo area dash, below steering colum dash unpluged all components that were pluged into phone module, cut all zip ties holding wires pertaining to phone module(looked twice cut once). Reassembled and now my OBDII plug on my 04 crew 4x4 5.6l aint worken. I have tested the scangauge on a 05 mustang it still functionial so thats ruled out. There is one orange wire lead like a 20 or 22gauge that has been cut(not by me) thats coming from a fuse box with 3 fuses in it(allgood) that leads to the 3 dial controlers below the stereo unit(ie ac fan and temp). Any ideas feedback would be much appriciated..im at a stand still atm and need some ideas to bounce around. Thanks On a side note how do ya post pics on here cuz i got a pic of the wire and fuse box to post.

 

did you check your fuses??

 

the fuse panel on pass side near right kick panel..they aint labeled!! fuses for days in there..the only thing that aint worken is the obii connection..just testing the scangauge on a 02 chevy truck still worken.

 

found the problem..dont know how it happened and ima gonna be thinking bout it..but fuse #41 blew..so let it be known fuse 41 on a 04 screw = obii module

 

That fuse also works your cig lighter too.My buddy found out it when he hooked up his new EDGE at the port.

 

the orange lead your talking about might be the illummination lead for the radio.
