And I ran into what appears a relay of sorts down by the washer bottle on the driver side inner frame rail - it has 7 wires into it. What is this guy? Nothing on the Wiring Diagram with 7 wires that I spotted.. A/C related by chance because the A/C was deleted on this car..
I would like to leave the wires intact but it is a pain to get a grinder up by brake booster to hog the hole bigger on the strut tower firewall side.

Any input?

Thanks guys!

Use a drill to slot the holes. Just get one with a sharp bit. What I did on mine

Yupp actually ended up using a metal "hogger" bit on mine.. Mike everytime I see you post something I always feel a bit of a need to hide your posts from my wife.. WTF?!?! Alright any idea on what the "relay" is I am referring to? I have enough air tools that this is mundane but still... hate to have to grind it too..

Meh moot point now - ended up using a "Uni-bit" = progressively larger drill bill THEN the hogger bit and I was golden with out having to cut or remove any of the harness. Thanks for the tip on the hole slotting Mike. Speaking of slotting - I am the proud owner of Highway Gangbang #'s 1, 2, 3, 4, AND 5...
Ok ok I am keeding.. my wife would SOOO kill me if I bought #5..
