What he means is there is a resistance wire or at least in my 72 K20's case what's ( I thought all our trucks had one) called a ballast resistor in line to that wire that cuts voltage to about half where the newer electronic systems require 12V to operate correctly. It looks very much like what is in this link and its mounted to the firewall above and off to the side the distributor
