Hey Merv-
You can see where I have put mine through just below the fuel pressure gauge in the pic. It worked out well there with the holden loom, in that with the cable length the ECU ended up in a nice spot behind the door post on the passenger side, that I will cover with a kick panel. I actually routed all my wiring, including the the rear lights etc through this one large hole, and was abole to reuse the holden bung that made it nice and neat. The only other hole I have is a small one for the front lights\horn\fan, which comes out above the foot box and will attached to the underside of the left front gaurd.
