Today I made sense out a large wire harness , I had to split two 1" 20 wire sections and pull those two from the main harness...Opened it from the taillights to the seat back location to ID and relocate the factory amp and CD changer …. yeah old school but's part of a complex factory sound system. Then capped off the rear defrost, hatch release, hatch open warning switch and sorted out the taillights . Amazingly when I powered up the harness everything worked as intended. Tomorrow I'll assemble the aluminum bed sections .
