I posted this in another thread. I carry tools for most situations. I also carry in a couple small plastic cases an extra relay, a
starter relay, a spare Eastern Beaver headlight relay, spare fuses, a couple pieces of wire, a tire gage, a little electrical tape, several wire tap connectors, a spare throttle grip, and an ignition
switch bypass setup. A small compact digital volt/ohm meter comes in handy as well. The PDF's of the circuit wiring on my phone, the full service manual PDF on my phone and the Android version of TuneECU. Anything beyond that, I'm calling my Good SAMs Road Service.
