I was given a Crane XR-3000 Points convertor and a PS-91 Coil. I want to install this in my (11/72)-73 240. Does anyone know how it wires up and can I use my Tach. I have read a lot of forums about this and some talk about the tach either frying or not working after the install. I don't have the manual from Crane but have downloaded one, but it doesn't seem to include my setup for the coil and tach. I do know the Red wire from the module goes to the + on the coil and the Yellow to the -, but how does the tach wire in. I have the B/W wire and the G/W wire on the original setup going through a ballast resistor. Do I leave the ballast resistor inline with the PS-91? I wouldn't think so since it doesn't require a ballast resistor. This would sure solve a lot of my problems with this car (I HATE POINTS). Any help or pictures of a similar setup would be appreciated, even a wiring diagram sketch would help. Thanks:confused:

If you go the the Crane website, you can print the package insert and instructions.
