The transplant of the entire B21FT drivetrain, suspension and LSD rear from the '83 flat nose to the GT is now almost complete. With all new bushings, stainless brake lines and various other upgrades, it is pretty sweet. The job required a total transplant of the body wiring harness, so it has the wiring of an 83 with the R sport gauges and 79 headlights (square H4s) and tail lights. One thing has me stumped, no power to the low beam headlights. It is acting like a bad small headlight relay, except there does not appear to be a 2nd headlight relay in either the 79 harness nor in the 83. There is no voltage at the low beams. Headlight switch, bulb relay, turn stalk, high beam relay have all been checked. It has me stumped. Any of the Bricksters have the key to what I overlooked?
