@bladefury, here is what I did:
This image was poached from ragefactory from earlier in the thread. Take the wire bundle and run them through one of the holes left from drilling out the Tower #3 standup. I had to widen my hole slightly to get all six wires to fit through, but not by a whole lot.

There is a 1" access hole nearby on the playfield, near the standup target. Drop the wires through the playfield and secure the tower down with the playfield plastic installed. You may have to prop the playfield up on the kickstand and feed the wire through with one hand while guiding it down from the top. I found that it was easier to run the wires through the plastic first, then finagle the plastic and wires into place, then tighten everything down. This pic shows where the wire come through the hole, towards the bottom.

I then cut the wires to length and soldered them to the GI bulb that was close by. Note, I did install a couple of nylon wire guides to make the install clean.
