I just got my Accel DFI, and hookup seems pretty manageable, but how did you guys route the harness (and big connectors) through the firewall? Where did find a hole that big, or did you have to drill one? How big? Is there an OEM hole somewhere? Please help.

I used the hole saw from doing the oil pan return line. There is a spot in the passenger side foot well close to the console that I used. Of course the motor was out when I did it so it was easy to find a spot. I drilled 3 holes in a triangle pattern, cleaned up the rough edges, and it worked pretty well. The harness runs in the console up to the passenger seat, then out and under the seat to the DFI unit itself. I may be able to get a picture if you need it.

If you could take some pictures, I'd really appreciated. Thanks Greg.
