i can tag the rev counter direct off the coil i think.
i have a black, black/red and brown
i guess these 3 are the live's and earths. im not sure either the black is live, or swiched same with black red.
i found a thin black with yellow trace too. on the cav it went to the carb some random couple of what loom like vacumm unit things. but i stripped the loom down and it joins onto the reverse plug loom. so ive no idea what its for.
