UPDATEWell I got started on the conversion.
Took the dash apart.

First un-attach the cables from their points. The first is on the drivers side above and to the right of the gas peddle.

The 2nd is on the passenger floorboard to the right and a little up.( I had already unattached it before the pic)

The 3rd is behind the glove box. In between the blower motor and the ducting.

Next unscrew the controls and pull them out just a tad so that you can reach the connectors
This is the lights connector

This is the ac button connector. Kind of a bitch to get off. There is a clip on the underside that I had to snap just to get it out. Weird design. It doesn't just pull right off like one would think it would.
I also forgot to take a picture of the main connector. Its and easy pull no problems there.

Next I had to cut a notch in the left side of the mount bracing for it to fit. (Thanks 'disker' for the tip!)

See...

Starting to look good!

Now for the wiring. Fortunately enough Isuzu is smart and uses the same color wires from generation to generation.
And since I was smart I got the clips from the 2nd gen controls along with the control cables. (Thanks 'disker' for the tip on pulling the longer control cables!)
So to keep from wrecking my stock wiring I decided to just add a bunch of male flat pins and plug them into their proper place.

All done crimping!

Well its dark out now and a real bitch to work in the dark. Plus I figured out that the light bulbs in the new controls are burnt out...(took me about 10 minutes to figure that out...) Ill have to pick some up in the morning before I finish up!
Lookin good!
