Well...after you left, one of Blake's installer buddies from Jasper stopped by. He has a civic like yours and I think he wanted to bounce some ideas off you, but he missed you. Anyhoo, as everybody was leaving, I asked if he had ever done an Explorer like mine and wondered what his opinion was. I had planned on asking what he would charge, and I was going to set up an appointment to go see him at his shop, but he asked if a had a grommet and said "let's pop a hole".
I brought it inside, and he did some exploring (no pun intended) and found a place on the firewall to drill thru, but when we pushed a fish wire thru, he couldn't find it under the dash. He ended up prying the cowl up (as seen in the pic) and realized the thing had a double firewall. He ended up having to remove half the dash under my steering wheel, drilling from the inside, and fishing the wire thru TWO holes that are 90 degrees from each other. I felt so bad that a 10 minute job ended up taking almost 2 hours.
I now have about a foot of slack under the hood, and the other end laying in the back floorboard. If it hadn't been for William, I never would have gotten done.
