Outfitting my Fit to be a toad or frog behind motorhome.
I don't want to use the fit's wiring, will keep stoplight and turn signal lights separate by installing a socket in the stoplight housing, power to come from motorhome.
I will have the front off installing the baseplate so I will have easy access to front, if anyone has done this, I would like to know best route. Two choices run under car or under carpet, at the spare, branch right and left.

 

No easy way, so without anybody responding I routed thru motor area under battery down firewall, along drivers side, crossing to center at about center of rear doors, came up thru spare tire well near top drivers side. up to each side, behind taillight housing to the installed 3157 bulbs mounted from the bottom of the taillight housing. Only thing left is cutting into the brake switch green wire to send brakes applied signal to the MH.
