engine and drivetrain Ground locations

[bnam]

As I go through the electrical system looking to clean up grounds, I hoped to find a list of ground locations. Search did not yield anything so I'd like to start a list that more experienced members can add to.

Engine Bay (this is based on 74Tii):

1. Between relays and brake fluid reservoir (harness and engine ground)

2. On block near alternator (for wire from alternator)

3. On firewall about a 18" from driver side fender

4. At starting relay bracket

5. At mount screws on both side lights

6. At AC relay bracket

Cabin:

Haven't looked yet -- hoping to to get some pointers

Trunk:

Near driver side tail light

There might be several ground wires at the left-side heater box mounting stud (inside the cabin).

There is an important ground on one of the screws that mount the voltage regulator and also one on the mount for the horn relay--at least in my '71.

in the cabin of my 76 there's a ground under the instrument cluster and above the gas pedal.

This is valuable information.  Thank you, contributors.

This one is easy to miss and VERY important.  As said it is under the regulator and secured by a sheet metal screw into the fender.  On the back side it can rust from the elements and create a very bad ground.  One symptom is a jumpy fuel gauge needle.  I through-bolted this ground connection on cleaned metal.  Jumpy fuel gauge needle cured.
