1967 firewall holes ID

Help me ID these dash holes! Prizes included smileys and thumbs ups.

I will update the lists as I figure them out.

Notes:

1) This picture is stitched together from many pictures by software, so it is very funky looking.

2) The gas pedal is my own adaptation of a 69 pedal with a lokar cable, so you can ignore it.

3) Red holes are custom.





1 - firewall pad
2,3,4,5 - foot windshield washer pump
6 - firewall pad
7 a,b - parking brake
8 -
9 - Speedometer cable
10 - main wiring loom (to headlights, etc)
11 - Windshield wiper hoses



100 - Transmission Harness (neutral safety switch / backup lights)
101 - A/C Power harness
102 - Firwall Pad Pin

104 - Accelerator pedal / gas pedal linkage
105 - Speedometer cable clip on engine side of firewall
106a,b - Fuse box mounts
107 - Accelerator pedal mount
108 - Accelerator pedal mount
109a,b - A/C related vacuum hoses.

111 - Fan blower housing stud
112 - Heater / A/C box stud
113 - plugged for A/C??, otherwise heater core hoses

115, 116 - Accelerator Pedal, 6 cyl only? Not sure what was here on an 8 cyl

141a,b - Accelerator pedal linkage, 6 cyl, not sure what was here on 8 cyl cars

1967 Assembly manual notes:

Electrical Assembly Manul
Many many pages of relevant stuff. Note that the A/C is an add-on, and is in a separate section at the end of the book.

Interior Assembly Manual
Page 7 - Firewall / Dash Panel Sound Absorber - Left half of the diagram seems to show the pins accurately, top center and far right pins don't seem to line up with holes properly. (Especially top center)

Body Assembly Manual
15 Body Front Plug Buttons and Cover - Various heater related plugs when not in use
16 Body Front Sealer and Adhesive - Shows the adhesives and sealers for most scews/etc on the firewall, with descriptions of what the things are.

Chassis Assembly Manual
Pages 6,7,8 - Installation - Max. Vacuum Components, Hose Routing - Engine Compartment - Maybe some hints about vacuum hose holes. It's a bit vague.
Pages 18-22 - Various clutch and brake related diagrams
40-41 - Gas Pedal
46-47 - Steering Column

Added some notes about the assembly manuals, and filled in the things you all added.

Thanks guys for the help so far, I've nearly figured it all out. I have some hunches on what is left - at least one may have been done by me over the years.

Are you referring to this thread?

http://forums.vintage-mustang.com/vi...ml#post4181205

That wasn't me, but I think between these two threads, it's (almost) all there.

Can anyone name this hole? I filled mine in and I don't know why. On the engine side it would be directly above the two heater hose holes (which are blocked off if you have A/C) and it's tucked under the upper lip of the firewall.

Think it may be fan motor power wires...

That would make some sense - I can't seem to figure out how the wires get to the motor in an A/C car. It seems like they go outside but the motor itself is inside? The assembly manuals don't seem to illustrate this anywhere that I can find.

Edit: One page shows a hook that hangs in that area that holds up the vacuum lines.

For AC they stay under the dash. Motor is in the cabin.

Only lines (on 67 -68) to engine bay are compressor electric line (single wire near pedals) and vaccum hoses to reservoir and water valve.

Think the hook holds both the duct and vacuum hoses by the glove box...

No no, there's one on the firewall near where that hole should be, and it holds the vacuum lines to the firewall in their path from the holes over to the coolant bypass valve and vacuum reservoir. It should be to the left of the export brace holes.

I can post a scan tonight.

Anyways, yeah, I probably should figure out that hole before I put everything back together because I'm not messing with it after the A/C box goes back in.

Sorry for hijacking this thread, but would the 67 holes in the firewall match the 66?

I think they are vaguely similiar. Might find some more info here:

This was from the other VMF thread mentioned above.
