I have put mine in heat shrink tubing. 1st I take off the plug ends and run all the wires through and then reinstall all the plug ends. I usually mark them for what color goes where in the plug 1st. They are not to stiff to run in the holes I drilled in the cross members. The next one I wire up I'm going to use small wire loom I have from work I think it looks more realistic than heat shrink tubing but once the truck is together you really can't see the wires to much anyway.
