hi all , i have a new wiring harness for the 39 chev , master85 . the original wire runs up along the roofline - drivers side ( under the headliner ) . i do not want to remove the headliner & wreck or disturb it . options 1. cut holes in floor , run along frame , cut hole in trunk & bring up . option 2. run wire on the floor of interior . i'm concerned about the frame route because of weather & possible heat from exhaust . & the floor route , will just clutter up the floor . any learned comments are very welcomed . frank
