I have a kit car with a rear mounted 1982 RX-7 13B engine. I am installing a new wiring harness since the old one was completely cut to pieces. There are 2 ICMs mounted on the side of the distributor. They have 2 leads. One of the leads comes from the negative coil, but I do not know where the other lead goes. Can someone tell me where to connect the second lead?

there is no negative coil. You have a leading coil and a trailing coil along with a leading ignitor(icm) and a trailing ignitor (icm) the one toward the pulley side of the engine is your leading ignitor. If you look at the ignitor closely you will see a C B on them along with a -+ . Connect a wire from the leading ignitor (C) prong to leading coil - and a wire from the (B) to the leading coil + . Do the same for the trailing using the trailing ignitor and coil. You will also need to run a switched 12v power source to both coils.
