67 Dart 270...Project Old School

This week I began chasing down electrical issues in the dash.
Thetemperature guage doesn't work, the factory AM radio doesn't work, the speedometer doesn't work, the right turn indicator light doesn't work, the oil pressure light doesn't work, the emergency lights don't work, the emergency brake light doesn't work, and the dash lighting is very dim.

I started by pulling the ash tray out of the dash. I then pulled the radio out the ash tray hole. I found all of the wires cut to the radio and some splicing for power. I am assuming the previous owner had a different radio in place of the factory radio. I cleaned up all the wiring and I noticed the plug that connects to the back of the fan speed switch was disconnected. I thought I had found the reason why the fan wasn't working, but even after I hooked up the plug, the fan still doesn't work.

I dropped the steering column and pulled the instrument cluster. It was immediately apparent why the speedometer didn't work. The speedo cable wasn't hooked up. When I reached down to check the cable the steel cable came out of the sleeve. Now I know why that wasn't hooked up. I replaced all the bulbs, except I am missing one of the plastic sockets that screws into the back of the intrument cluster. Does anyone know where I can get one? The ones at Autozone were too small.

I put 5V across the temp guage and it swung across the gauge to hot. That leads me to beleive the temperature guage is OK. I already replace the temperature sensor in the engine with the correct one. I ordered the correct engine sensor to work with the oil pressure idiot light.

At this point I ran out of steam and headed to bed.
