as some may know, i have a 71 fj40 with a chevy 327. i'm trying to make the original gauges work. 1) what is the alternator gauge supposed to be hooked up to? 2) the temperature gauge has two wires, but the temperature sensor on the 327 has ablack tube coming off of it, how can i make this work? 3) same question for the oil pressure gauge, two wires but the 327 uses a tube with oil in it. any help or suggestions would be appreciated.
