I just purchase this nice truck at auction and the after market radio had
been removed. All I have is the two seperate wire bundles.

I purchases a OEM Ford radio that fits this truck. It takes the two L shaped
connectors that were originally on the harness. To get a pair of these
connectors, I salvaged them from a '92 Ford Taurus.

The connectors are exactly the same and the radio was identical, however the
wire color codes are different from the F-150.

I managed to sort them out until I could get the radio to work but I have no
back up power when the switch is turned off and I loose my clock and station
settings.

When I pulled the Taurus radio out, I found an addition single wire
connector between the two "L" connectors but can't find a corresponding wire
in the F-150 harness. I originally thought that might be for a power antenna
but now I wonder if it is for the back up power.

Does anyone have a wiring diagram for this truck or the radio connectors. I
looked in the Haynes and Chiltons manuals at the auto parts store and
neither had a diagram that included the radio. (I'm seriously disappointed
about this lack of information in these once useful manuals. Bentley would
have this and much more.)

Thanks,

Steve
