purchased ground wire kit on ebay for 99' cavi z24.Anyone know proper install procedure?

unhook your battery.. both sides, undo all of the ground wires and reattach new ones in their place.. enjoy the benefits

what r the benefits?

better grounding? less resistance for electrical flow = more electrical current available.. (brighter lights, cleaner sounding acoustic amplification

o.k.

So it's just the wire from the battery, to the tray, and trhen to the motor? Please tell me there are more grounding wires elsewhere.
