anyone know a good guide to wiring up a vantec for duel motor control? or what each of the codes is?

i believe ma1, mb1 are battery + and - for one side and mb2, mb1 are the same for the other

the G1 and G2 are bridged but whats +1 and +2 for?

same with the Brk and Opt

help would be appreciated

Massive thanks for Ian watts btw for the vantec, now just got to wire it up
