It does not matter. If you study the descriptions you provided, then 85 is either ground or hot and 86 is either hot or ground. That is, if you feed voltage from the ignition switch to 85, then the ground is 86. If you feed 86 from the ignition, then 85 is the ground. 85 and 86 are the energizing circuits. It does not care which is positive and which is negative. They tell the solenoid to energize the other two terminals. Ciao, Russ Neely

Unfortunately I have two diagrams as to what goes where. (a) - 30 to starter + 86 to ground 85 from ignition switch black 87 to starter solenoid (b) - 30 to starter + 85 to ground 86 from ignition switch black 87 to starter solenoid And your choice would be?
