Instrument gremlins.

If your fuel gauge is working then the small stock voltage limiter behind the dash is working. The temp gauge issue is either can be anyhwre in the PC board, the temp gauge, then wires and bulkhead connector out to the sender, the sender itself, or the sender ground in the block. If you want to try to figure out the stock temp gauge, then disconnect the wire from the temp sender and connect it to a 12v test light; you should see a pulsing light. If so, then all is good to that point and it is just the sender. If not, then you have to work your way back into the instrument panel and find the problem.

The instrument lights out is often casued the dimmer rheostat in the headlight switch. Easy to replace the switch. There is an INST fuse in the fuse panel to check first though. The instrument ligths wiring is described in this thread: http://www.forabodiesonly.com/mopar/showthread.php?t=296230

If you speedo is reading 25 mph all the time, even stopped, then it is in the speedo itself. It's not clear about when it is doing this. Somone has fixed these and has posted on this forum somewhere, but replacement is the most common fix.

Okay. This may, or may not help. I had absolutely no time to mess with the car after posting this. Because while messing with the car, I lost the keys to my van ( which is my only transport ) Since I was bleeding brakes that day, I thought, " Oh god, they fell out of my pocket, and into the massive sea of leaves, in my giant driveway. That lead to me having to drive the Duster Late friday night. Since I had a 6 mile journey, I was actually more able to see what, it does, and doesn't do. (Before I was tooling around the driveway.) The dash does light up. It's just awful dim, so dim you don't notice the dash lights during the day. Plus the speedometer functions normally once you pass 25 M.P.H., I have no blinkers. Maybe that has something to do with my H4 headlight wiring. The confusing thing to me is, the front harness shouldn't affect the rear lights, right ?
( These are my test runs to see if the car would idle in park, and in gear ( had no brakes yet ) . To check pump shot, and to check cruise. Coincidentally No blinkers.)
