This is an overview of my ground buses (identical on both of my cars):

The bus is 4 gauge battery cable from the top of the engine to the radiator bracket:

then 8 gauge wire to the front of the car (the stainless plate behind the headlights is used as a ground block). Both junctions behind the headlights are tied into the front ground block with 8 gauge wire.

There are 5 ground junctions in the original harness:
- One by the bulkhead connectors
- One in the relay compartment
- Three under the console
These are connected to the bus in their original soldered state:

Wires originally junctioned at the radio bracket have been connected directly to the bus with a bolt. A new wire grounds the radio bracket itself to the bus.

There is a ground block in the ECU compartment:

The relay compartment bracket doubles as a ground block:

The bus has its own connection to the battery:

I just found another ground junction hiding behind the central A/C duct:

This most likely is the ground junction for the inertia switch and the instrument cluster (two trouble spots).

6 of the 7 wires on the rear bulkhead bolt have now been accounted for:
- Junction behind the central A/C duct
- 3 junctions under the console
- Junction in the relay compartment
- Junction by the bulkhead connectors

I will be tying this newly located junction into the front bolts of my ground buses in the near future with short pieces of battery cable (that is why that bolt is there -- to allow me to add grounds to the bus as necessary).
