After installing a new Pioneer 940BT head unit a few years ago I started thinking about other ways to upgrade the old Expod. All the new cars and trucks have backup cameras so I said why not the Expy. Anyway I tried to keep it simple and just ordered a compatible Pioneer camera and had at it. The installation went pretty smooth except trying to locate the darn reverse signal wire from the Ford harness to connect to the head unit harness. After a ton of research on all the forums I was able to locate it fairly easy and splice into it with a heat shrink butt connector. The reverse signal wire ended up being over behind the driver's kick panel in the main harness. It's black with a violet stripe and feeds to/from that big connector that's got a bolt running through the middle of it securing it together. I'll post some pics below for anyone else thinking of doing this install. I took the pics before I finished taping and tie wrapping everything back together.

Ford reverse signal wire located behind driver's kick panel....

Here's a view looking from the center console area....

Here's the camera mounted to the tail end of the driver's side frame rail...

Feeding the cable up to run forward through the driver's side frame rail.... (used a plumber's snake...)....
Exited the frame rail forward nearest the parking brake cable ....

Tie wrapped with the parking brake cable for security and run through it's grommet up into the cab floor area nearest the harness....
From there just run under the carpet and to the head unit as needed ....
