Need wiring help 73 duster

[dan0340]

Hey guys, another question here. Working on my sons 73 duster. It’s a wiring nightmare that’s new to us. I have a good wiring diagram but I’m have trouble with a couple of things. There are multiple things that don’t work in the dash, blinkers, emergency flashers, key buzzer, oil light brake I dictator light and blinker indicators. The blinkers were half working and now most are just solid light. Anyway I have some plugs dangling without homes. I’ll attach photos. I’ve got one down by the driver kick panel. Looks like a grey and blue wire. Then I have a black plug with blue wires going into one slot and a blue with white stripe on the other side. Then I have a little grey plug with brown and yellow wire. Those last two are dangling behind the fuse box. Let me know if someone know what these go to!

Photo 1 looks like seat belt body connector.
Photo 2 is seat belt buzzer.
Photo 4 is map lamp switch.
Go to mymopar and search for 1973 Dodge chassis service manual and look at connector chart on pages 8-168 thru 8-172.
Dodge Dart and Plymouth Duster have identical electrical diagrams.

THIS!!! If you don't have the 2 manual volumes, run over to MyMopar and download them. Not all the connectors are there, but most.

Take stuff that doesn't work one at a time and repost here, EG brake lights. The brake light switch should ALWAYS be hot and gets power from one of the fuses. So get power to the brake light switch. When pressed, the switch feeds power TO the turn signal switch, usually on white. So you can heck that at the TS switch connector at the steering column. With the column switch centered, and the hazard switch off (wiggle it they can get intermittent) brake light power should then be routed to the left and the right turn signal filaments.

Post back here as you progress and guys can answer your questions as you go.

I think #1 is the clutch start switch and #4 may be the t/s or hazard flasher plug. JMHO
