I use a colour detector to find mine. Also, easiest quick way is to use an ohm
meter and see which wire goes to which plug. Then I just tape mark it or cut
the ground lead a little shorter than the hot lead.
Got my tw2 yesterday and that's a nifty gadget! Now if I could get a tw1 I'd be
a happy camper!
