HEI Module
I've just aquired a new engine, but I can't seem to get it to fire. It has an MSD HEI module and blaster coil (installed by the previous owner) and the wiring was more then a little screwed up when I got it. I think I've got it sorted out, but could someone verify it for me?
Three wires out of the module: Orange, Black and Red. I've got the orange on the pos. of the coil, black on the negative, and Red as keyed power to the module.

Sounds OK. There should also be a white wire from the MSD that connects to the coil output of the distributor module, which fires the MSD system.
