You could try Radio Shack but I think you're going to need a high power rheostat so you might have to go to an electronic parts store. You need the higher power because you will have up to six (or more) incandescent lamps, with lots of inrush current, paralleled together. A couple of online stores to try are Allied Electronics (www.alliedelec.com) or Digikey (www.digikey.com). Good luck.

The high capacity rheostats are a little expensive.
I just mounted the stock Mustang dimmer switch up under the dash.
There was a thread on this a week or so ago.
Good Luck,

Another reason not to throw unlisted donor parts away. I am going with the stock Mustang device. Ugly and solid, but hidden.

I was part of last weeks thread on this; I then installed the donor dimmer on the back side of the 2X2 to the left of the steering wheel with velcro; hidden and works great.

The original post was from 4/28.

All,
The Mustang dimmer unit is a high-wattage rheostat packaged horizontally with an aluminum heat sink.
Best regards,
Chuck

The 25W rheostat at the above link will be at or above it's rated value. I just checked into this stuff for a forum member a couple of weeks ago. Each of the bulbs which came in my SW gauges draw a bit more than .30 amps at 12 volts. So, if you have seven bulbs that's a total of more than 2.10 amps. Multiply volts by amps to get watts. That's at least 25.2 watts.

I've owned a couple of Toyota pickups and they use a standalone rheostat to control the dash lights (maybe other ricers also). Should be cheap in the local bone yards.
