I have the '67 Plymouth manual and the Barracuda supplement. Have wired electronic circuits and done alot of house wiring. Even wired AC and DC circuits on a sailboat but auto wiring seems to be a different animal. Using a VOM is how I knew there was no power going to the circuit boards. The wiring diagram shows 5 orange wires spliced that may go to the gauge/dash light function that were not there in the old wiring and not included in the new harness. Wondering if I need to make one???
