Heres a trick
You guys may know this trick, but I'll post to up my post count
What you do is pull the old cam up where you can get to the wires connected to it with a little extra room.
One wire at a time do the folllowing:
1) cut it off the old cam as close as possible so you have enough for step 2.
2) overlap the end of the new wire with the cut top of the old wire about 2 inches.
3) Use electrical tape and wrap from 1 inch below overlap to 1 inch above overlap so the old wire is now attached to the new wire. Try not to make it any bulkier than necessary.
4) Pull the old wire down thru the steering column (toward the floorboard) pulling the new wire with it until you can reach the new wire at the bottom.
5) remove old wire from plastic plug, and insert new wire into plug.
Thats it. I've done a bunch this way and it is pretty quick and works well.
Occasionally the fit is tight enough that the old wire pulls loose from the new wire half way down the steering column.
Don't stress.. you have lots more wires going down, just pull the wire back out and piggy-back it with one of the others.
Worst case the LAST one going down pulls loose, then just reverse the operation to pull an old wire back up and piggy-back the two back down on it.
