When I purchased my Assembly Manual I was sure it had a page that showed me what each of the dents in the firewall were for. Well who knows what happened to it but...
Need to drill a hole in the firewall for the cowl induction harness that goes from the throttle kickdown to the solenoid. Can anyone tell me which one and the diameter of the hole.

Why would you want to mess up a perfectly good firewall by drilling holes in it? You should just keep it the way it is and sell the flapper hood to me.

Just kidding, mine is about 2 inches below the lowest point of the wiper motor. That’s for the wires the go to the relay. It’s a round hole looks to be about ½ in diameter and has a strange looking grommet with a sort of nipple coming out of it. Mine had the ZL2 SPC DUCT HOOD & still has all the wiring and relays but someone that owned the car before me must have traded for a non functional (freaking moron) Anyway, I can try and get you a picture if you want.
