There is a black plate near the back of the inlet manifold off to the side of the brake booster. Has two bolts. I removed that and drilled three holes in it than fitted water tight glands that you can buy from jaycar. I would have around 20 wires passing through there with room for more. Depending on the size of the wire of corse.
Cheers.
