Firewall pass through diagram

[Gargemel78]

Is there a diagram of locations of what wires and which holes they are suppose to pass through on the firewall of a 73 charger? I think i was trying to use the hole for the vacuum line for the speedometer cable but not sure what goes where? Thanks again

Wiring diagram usually have where/what wires go through bulkhead connector.
See if there is one for your car.

If I understand your question correctly, the wires/harnesses all converge at the bulkhead connector. There are 3, eight pin connectors on the bulkhead terminal. The connectors join the interior harnesses with the harnesses in the engine compartment.
The link Fran Blacker supplied will show you the 3 connectors (see /1973/73CoronetChargerA.JPG diagram).

I don't think he means the bulkhead itself but holes and grommets on firewall

Nacho that’s exactly What I was asking, not sure where the speedometer cable comes through or vacuum lines for the heater box?

If you don't get an answer before then, i'm going to my pals house later this morning and I will snap some pics of his 73 charger firewall.

Does this help?

 

[Gargemel78]

Yeah I think so

I don't have pics and my car is 12.000 Kms away from where I am, but... ON MY CAR ( 74 ) the vacuum line for the A/C actuators goes throught the most outer hole to driver side. Shares the same Heater valve cable/wire. The grommet is molded for both.

Now the speedo cable, it should be the same than the E body pictured.

Do you have a picture of this molded geomet? I don’t remember ever seeing it. Does the cable that controls the heater valve pass through the passenger side of the car?

 

[Nacho-RT74]

Driver side... no I don't have a pic and my car is 12K Kms from where I am at this moment

73 rallye firewall...looks like it goes through just to the drivers side of the steering column.
