Why I ran the Motec M48 EMS on the Rusty Old Datsun it was important to get a good ground because the EMS needed it as a base reference. I was also running a 16v battery and a Bosch Motorsports 16v alternator. All it took to get a perfect ground was a #6 battery ground cable and a copper strap connecting the engine to the chassis at the alternator mount.

I jotted down a list of the connections I thought would be good to make:

1. Batt(-) -> chassis

2. Chassis -> starter (-)

3. starter (-) -> block

4. block -> head

5. block -> Alt.

6. Alt. -> Intake

7. Intake -> Dist.

8. Intake -> AFM

9. Intake -> chassis/dropping resistors

10. Drop. res. -> steering column/headlights

-The block:near the bottom; the heater hose clamp

-head: front/hoist bracket?

-Intake: middle; the EFI wires clamp or AAV valve

-AFM: Any bolt

-Drop. resistors: mounting bolt

-Steering Col.: preferably the headlamp switch bolt and/or the lighting rheostat

I still don't think 8 Ga wire would be approprite- too obvious. I'm going with 10Ga. 1000 strand wire. Not much current is involved.
