I am installing the single distributor and MSD that I got from Ben Millermon. Like a moron, when I took the old coils and distributor off, I did not make notes on the wiring. I figured the wiring diagram in the owners manual would have details and/or the new distributor would have detailed wiring.
Well, I cannot read the diagram in the manual and My car is different from Bens so his diagram does not include all the details.
I have it all wired up, but there are 3 wires that I am stuck on. The MSD and new coil are wired in, but I have 3 harness wires that I believe went to the old coils left over. There were 5 wires bundled together that went to the 2 coils and ballast resistors on the original setup. 2 black, 2 red and 1 solid brown. The black wires are hot with the ignition switch. The red wires and brown are not hot. I am pretty certain these are related to the tach, but not positive.
Anyone know what these wires are and how the tach is wired in the stock '77 308 GTB setup? Im going to be firing the thing up tomorrow and setting the timing, but I need the tach. I think the red wires go to the positive coil terminal and another wire mounting to the same post goes to the distributor. I think the brown is a ground, but not sure. Any help is appreciated! |
