Great write up. I just finished mine today less the tach adapter (some need it and some don't). I connected into the existing CD harness using spade connectors. I ran the primary power from the MSD in a wire loom across the back firewall (toward front of car) and dropped down through the rubber engine to body seal right to the starter. A couple of wire clips to secure the loom and instant power. I used the MSD coil wire to the MSD Blaster 2 as the coil wires in the original harness were getting crusty. Put every thing in wire loom, clamped or wire tied it for neat appearance, set the timing and back on the street. Thanks for the support, runs best it ever has.
