running wires into the door from the door jam proved to be a challenge.
i had 2 speaker wire, 2 solenoid wires, 2 window wires and a safety door release cable to run into the door.
the release cable is a bicycle brake cable ~3/16'', needless to say i had a fistful to run into the doors.
i tried the spring like door wire loom; it wouldn't carry half the wires and wouldn't work with the door hinge geometry on 55-59 trucks.
again, necessity is the mother of invention...
i drew up the hinge geometry to design my door wire loom, just basic pivot points and door locations.
using 3/4'' sq aluminum tubing and some 1/4x2 flat stock from home depot, i made these.
pivot is a 1/8'' roll pin.
door open
door closing
they worked out rather well.
2-#16, 4-#14 and the 3/16'' cable fit in with room to spare.
everything mounts and pivots on the door jamb.
i cut an over sized hole in the door and made a plastic bushing to guide the loose end in and out of the door.
