Time to dig into the dash. I already showed some of this with the posting about the switch for the greywater dump valve. Start by taking off the doghouse then removing the stock radio.
To remove the radio use a Din Radio Tool. The tool is these two U shaped wires. Around $6 from Advance Auto. The stock radio is surprisingly slim.
Here's the view without the radio.
Install a new radio using a custom bracket. This leaves some room in the old radio opening for a switch panel. Cut out a template from paper.
It measures 7-1/2" x 1-1/2".
Cut the panel out of an aluminum sheet.
See how many switches I can cram into the panel. I've bought a selection of toggle switches because not yet sure what all I'll be controlling.
Measure and drill holes for the switches.
Add the switches and label them. At this point they not really wired to anything.
With the new radio goes new speakers. The van only has two speakers. One in each door.
To take off the door start with the screw in the bottom right corner.
Pop the cover off the front of the door handle and swing out of the way. It exposes a torx head screw.
Unscrew and remove the handle. You have to wiggle the handle to work it free.
Use a small screwdriver to pry the cover from around the door handle.
Above the handle is another screw. Remove it.
There is a black plastic cover on the inside of the door.
Carefully pry it off.
This gives access to the one last screw.
The plastic door panel lifts straight up and off.
Here's what it looks like without the door panel.
Out with the old speakers and on with the new.
Put it all back together. I had one problem and that was in figuring out which wire was radio plus and which was minus. The wire color didn't match what the Ford manual said it was supposed to be. I used a voltmeter to trace which wire was which back at the radio. Problem solved.
