Tunnel - Firewall Holes

[goldgunner]

Any one have a photo or drawing reference of all of the Tunnel - Firewall holes labeled for use - purpose?

Some good info here on the conduits, but not the other holes:
OOOOOPS, What's in the tunnel?

I've searched about every combo of description query...no joy.

Thanks!

Please try this one:
What is the large oval / ovoid hole in the engine firewall / bulkhead used for?

What is the year of your car and do you have a pic to show what you are looking for?

Here's a pic.
Assumption is the top right hole is for the main wire harness.
What's the oval hole at bottom right?

Fuel lines run thru the left side out their own openings...

Electonic speedo drive, uses a large rubber cover that fits over that oval hole... if memory serves..

I have an early car, back end is apart.. My speedo comes out of the hole you are referring to.. not sure if its the same for your year or not.. hope this helps.

Goldrunner,

That 8mm stud to the right in your photo is the transmission ground strap connection point. The flat disc-space around it should be bare metal to insure a good ground. If you don't clean it off, you will have no end of electrical problems.

thanks Brian - with that reminder I should - I hope - remember to prep it well.
