I got a used pc111 usb for my '98 EV with the P8 ECU, but It didn't come with any wiring instructions and the CD isn't much help. I see where it plugs into the throttle bodies, but how do I know which side goes where? Also I suspect the single black wire with the eyelet is a battery ground? If anyone has a schematic or some instructions, that would greatly appreciated,
Cheers,
Aldo
