Help with wire identification please!

[1mightymopar]

I've switched from a standard dash to a rally dash on my 71 Challenger. There are some open black terminals and others i can't figure out where they go?

1. On the voltage regulator on the cluster, should there be an open terminal?
2. Yellow wire from the light bar, where does it connect to?
3. Wiper switch... Should there be an open terminal?
4. 2 open black connectors. I'm assuming these are grounds?? To where?
5. Orange/red connector by radio? Where does it go?

Any help is greatly appreciated! Thank you!

Schematics in your FSM should have all that information for you. It might take a few minutes of studying to figure it out.

I've gone through it all and can't seem to figure it out. I've got evryeveryt connected I think??? Don't want to miss anything especially grounds.

One of those black wires goes on the open terminal on the voltage regulator. Can't tell which one from the pics.

Red/orange connector goes to factory radio. Red=power, orange=lights.

Yellow goes to light above heater controls.

Thank you soo much!! There are 2 blacks.. One has a white stripe, the other is solid black and is shorter, right off the main harness. Thank you again. I've been racking my brain with this one!

Scroll down to post #18 for some rear photos of a wired rally dash (1970). Not sure if you will see what you need, but you may.
