i have been working on wiring my rb in and ran into a small problem. I do not have a eccs ground going into the m63 plug on the rb harness. there was a black wiring coming out of the other side of the plug but nothing on the other side of pin number 8. can anyone look and see where this ground comes from? it would be a huge help. I wanna get this think running.thanks

the ECCS is grounded through the harness near the upper radiator hose (i **** you not)

you dont need to ground anything when you wire the car.
