Hello. I have an 05' F150 and started my install last night but am stuck with several questions:

1. I got the factory wiring harness but there is a third harness that plugs into the factory radio. I am assuming this is for the steering wheel controls. I bought the PAC unit (knowing that it will not control the presets) and I am wondering if there is a harness I can use so I don't have to cut the factory harness? If so please send a link or a part#.

2. I have a factory Sub-woofer. How do I hook this up to the AVIC unit? I have read a few posts where a resister is required. Do I need to hook up power to the sub or just connect the Sub out RCA cables from the AVIC unit?

3. Does anyone have detailed instructions on installing the PAC SWI-PS unit in an 05' F-150? The PAC instructions are confusing.

Any info would be much appreciated.

Regards,

WFR

You may want to PM a mod to get this moved to the F-Series forum, this is the D-Series forum. Sorry I can't be of more help.

Actually installing the PAC unit was real easy once you get through all the documentation. Just installed on an 04 F150 w/o audiophile unit and it came down to connecting two wires. Give PAC a call and they'll tell you which ones to connect where.
