Just bought a SD JB Jr. for my Jaguar and have it wired up like so:
red & white wire from JB going to jag yellow wire
black and green wire from JB going to jag black wire.
does this seem right? I only know how to play the thing and don't know how to wire it. also, am I supposed to tear out the old wires and actually resolder everything or can i just splice and connect them?
