FYI, people who don't use the proper resistance resistors on their stick coils (COP-coil over plug) and with their analog 1985-'89 ignition boxes, have reported failures of their ignition boxes. One theory is that the OEM ignition boxes for the 5-wire/2 pick-up coils (an easy way to tell them apart from the 1990-'07 ignition boxes, which use one pick-up coil having 2 wires) are sensitive to having the same resistance as stock. Owners have reported failures of the OEM ignition boxes.
