I am trying to sort out the rats nest under the dash. Can anyone tell me what the pinout is for the square connector coming from the engine? The manual I have doesn't go into the detail of it. I know that one of them is + battery (larger gauge wire than others) and the gray is the tach signal but there is so much splicing and rewiring that has gone on under the dash that I can't tell were all the wires are going. If I knew what the were then I could cut all the old stuff out and solder in new wires. The reason for all of this is 1)a problem with the gauges not working properly all the time 2)tach working intermittently 3) no charging current at the battery. I would like to sort all of this stuff out and make it a little cleaner and safer. Thanks all.
