cluster connector

I already told you all this.

Dimmer controlled power goes to and through the fuse. ORANGE wire COMING OFF THAT FUSE distributes dimmer controlled lamp power all over the instrument panel, to the cluster, to the radio, the heater bezel, and according to what options you have, the gear selector quadrant, etc

If you look through the wiring section in your shop manual, behind the diagrams are pictorials of the CONNECTORS

In my manual 1974 Dodge service manual , page 8-153 is the ALPHABETICAL INDEX showing various components

In mine page 8-161, coordinates C-24 shows the dash lamps. Follow to the left and find the fuse. See where it says "CI-24" This is "Connector" "Instrument" "24" Notice that wire off the right side of the fuse says E2-20 O. This is circuit no E2, and arbitrary no. It's a no 20 size wire. That last letter, "O" means it's ORANGE

Go to the back of the diagrams, in mine page 8-177, and there is the fuse panel

On the diagram, near the dash lamps is "CI-10" Find this on page 8-176. That is what your cluster connector looks like

You would do well to map these all out by color and pin so you know what they do

Much of it is page 8-157, coordinates D-7

Those are your warning lamps and temp gauge, and voltage limiter.

EXAMPLE find the limiter, follow the wire off the left and up, it goes through CI-10 and says
G5-DBL. That means arbitrary wire no. G5 and it's Dark BLue

Go back to your connector and find G5-DBL. That is your power coming in from the ignition switch, hot with switch on

Find the ONLY ORANGE wire which is E2-20o That means arbitrary circuit no E2, it's a no 20 wire and it's "O" ORANGE. This is your dash lamp power coming in

The cluster MUST be grounded
