Last time I did this I actually took and old metal coat hanger, bent the ends so they would not puncture the rubber and used that to route through the loom. Works great for me because you can see/bend the hanger easily for the bend in the loom and then pull everything through, kinda like a wallfish tape.Thank you Dick, you are truly too kind. I am fortunate to be in a position where I am forced to find answers to questions that we all (60/62 owners) face sooner or later. I learn something new on every build, more often many things new. I share them here because I know how hard some of these things are to find once the OEM solution is no longer available. In this case I like the solution better than the old grommet and taped wire I find on them when they get to me. If something I post can help someone get closer to the truck of their dreams, cool.
When you run wire through the rubber looms,
-remove the loom from the door side
-run the wires through loom
-run wires through hole in door
-insert loom back in grommet
Or you can try to get your wires to turn those corners in place, no waaaaaay!
