relay ground wires

I'm chipping away at a non-running 1978 GS750. The next job is to update the wiring with the help of ValorSolo's color diagram "All wiring mods for 78 GS750".

I bought a Polaris SH775, mounted it under the battery box, and I'm creating a single point ground at one of its mounting bolts, a la posplayer. I'm interested in thoughts on the smartest place to route the ground wires that come from the relays in ValorSolo's diagram. To harness ground? Frame ground? To the battery negative post? SPG? I'll have four relays, all mounted on the right side of the battery box. If it's just a matter of keeping the wires as short as possible, then battery negative is closest with easiest access.
 
The relay grounds don't really matter. You can tie them all together and then run a single wire to the SPG ; that would be cleanest but not nessesary. The length of wire doesn't matter other than aesthetics.

The SPG is only really important for the main connections between the battery and R/R and harness ground.
 
Just to expand on Posplayer's answer. The ground on your relays are only carrying the current that your relay coil uses to close the relay contacts. The high current return from your headlight, starter, etc. will not be on this circuit so you don't need to worry very much about distance/gauge. You do need a clean/solid ground as with any circuit.

IIRC about 80 mAmps and it only takes about 6-7 Volts to trigger the relay and there is no penalty for any of it once the mechanical contacts are closed.

Probably more that OP wants to hear.
