last bit of help

First I want to thank everyone for responding to my recent posts, the advice has been phenominal. I am now installing the Huntley Racing MAF and have hit a couple of snags.
1. How do I get the wiring harness from the MAF to the air/fuel control box I installed in my center console. Seems like the easiest way is to drill a small hole in the back of the firewall right behind the rear seats. The idea of drilling a hole in my car makes me somewhat queasy, though I haven't ruled it out.

2. What is the best way to tap into terminals 2, 7, 22 on my DME? How will I know where they are? Fiddling with my DME also makes me queasy.
