Guys, I found a small plug in my truck where the PO removed an accessory, but left the wiring in place. Anybody know what this plug might go to? GPS maybe? The PO apparently removed a number of accessories and I'm still trying to figure out the wiring he left behind.

 

looks like an older cellphone antenna plug

 

Or a sattelite radio. It looks like the one that came with my XM radio unit.

 

Appears to be the wrong configuration for any type of power plug. 12valvedutchy may be correct about the cell phone antenna, or maybe an XM/Sirius antenna.

 

looks just like my old Sirius antenna.

 

Yup, XM or Serius satellite radio antenna plug. Look for an antenna on the top of the truck.

It will work for either system.

 

Looks just like my old XM Antenna plug

 

Posssibally a disc changer...

 

Wait, it goes to one of those weird clamp things found in the 5 gallon bucket in the off topic threads.

 

12 volt pocket pleaser for truckers?

 

I'm betting the XM radio thing is right. Thanks guys.

 

Those antennas are usually magnetically mounted on the roof. However, since they can pick up satallite signalls through plastic materials it's possible it's mounted within/under the dash. If so, I'd think reception would be poor or limited.

 

And how do you know this

 

Yep, looks just like the antenna plug from my XM.

 

I finally looked on top of the truck and found the magnetic sat radio antenna. It's a lot smaller than I imagined. The PO ran the cord up through the front cab post and out through the roof under a clearance light. Nice job. I'll just leave it there. Thanks for the help, guys.
