help on opti wiring

[texlurch]

Anyone know the pinout or color codes for the 4 wires on the opti? I know one is power in (+5 V or so), one is low res out, one is high res out.. not sure on the forth one..

Trying to troubleshoot a starting problem/no spark. Opti is new.

thanks!

Lt Blue/Black = High Resolution

Do you know what voltage should be on the pink and red?
