I have question on starter relay. What was the"spare" red wire used for stock?i know i have red to starter, red to battery. Does the red/white wire go to r/w of stock switch? Also does B/w wire connect to b/w on right bar switch? Its a hardtail but want to use stock switches. Also as far as ground...top engine mount has ground wire..should that be connected to engine? Like say battery to frame..then frame to engine? Also brake light only has 2 wires. I assume its grounded by mounting? Does one wire go to switch and other to switch and fuse box for power?Annnnd...the aftermarket headlight has highbeam indicator..can i simply wire that to neutral switch instead?
