A little background. I replaced my 1971 wire harness with that out of a 1973FJ 40. Everything works including the blinkers to a point…. Daylight time, without the headlights on, the blinkers work for 10 blinks then they start to slow, eventually they stop blinking entirely…..the light just stays on. At night time, with the headlights on, they blink 2 to 3 times then stay on solid. Seems like a dropping voltage issue or a blinker relay?
