Geez, I'm glad I don't have to pay myself wages to build this thing, I'd have been in bankruptcy court long ago. Another long day gone and I'm still wiring. The switch panel is permanent, but I decided to do a quickie temporary on the instrument panel. I can decide better on layout as I drive it for a year or two. The gauges are snugged in place, but need a few wires and lights and air tubing. The tach needs to be calibrated before it gets final installation. I have a strobe tach from China (ebay, 20 bucks) to get an accurate RPM reading at idle and against the governor, then I'll set the dash tach to match. There will eventually be more switches in that panel, but these are the four I need right now. Fuel transfer, air compressor, driving lights and tire chains. There will also be four single pole, double throw momentary switches for the air bag controls and an assortment of others. I discovered that I needed a longer terminal strip, so I dug around in my junk and came up with one.
The gauges are, left to right, turbo boost, tach, saddle tanks fuel level, dual air gauge (2 needles in one gauge) for front air bags, system air pressure, dual air gauge for rear bags and application air pressure for the tire chains. They don't match very closely, but I paid 45 for the tach, 14 each for the dual air gauges and the rest were free, so they suit me just fine for now.
Also a picture of the finished rear door... finished enough for now. I need to get done working on this thing and get on the road.
