don't have the D-150 back yet, but there are more than a few items to still sort out.
one of the upgrades for the 83 D-150 is the dash bezel, the section above the heater control on the 83 was blank, some of the later D-150's have a small storage pocket there, some have a "message center".

I got one of the message center modules, and in working with a very cooperative manager at the local Kinko's-Fed X store, got a new cover plate made up that will house indicator lights for
AC on, electric engine fan on , emergency brake on, tranny in reverse.

the lighting is simulated, I'll probably use colored led's, blue for AC, green for fan, red for the brake and yellow for the reverse indicator.
also adding power windows and door locks, and a few switched accessories
the rocker switches in the top row L to R are, power door locks, I plan to have one central switch to lock and unlock both doors, the next switch is for the driver power window, the R switch is for the passenger side window.
these are double pole double throw momentary switches
the two on the bottom are on off rockers, one as a manual override for the electric radiator fan, the second to light the bed light that will be added

I have mocked up the wiring for the power windows, can get the motor to spin forward then reverse depending upon the rocker position. I'll look around and pick up a door lock kit this week
