I am fitting the loom and need to earth to chasis in three places with a mass of earth wires at each point- any ideas as to the best connectors for this?- I could use a giant sized metal o ring type conectior and then rivenet and bolt to chasis but the crimp would need to be massive to get all the wires into one connector.... Any ideas?

thanks.

Ring connector on each cable then 1 long bolt into a captive nut OR lots of small bolts into captive nuts. JD.

Personally I prefer cross connecting all the earths and lots of local earth point so that if one fails the others take up the slack.
