A 93 has a solenoid on the fender. I know, same year as mine.
Looked up diagram on alldata and there is a red/light blue wire that goes to the fender solenoid (or relay depending on who you ask) them from there down to the starter. If the fender relay wont energize you wont have power down at the starter unless you have a 12v hooked straight to battery on one side of the starter solenoid.
In other words both wires need 12v to start. One is hooked to the battery other hooked to fender relay/solenoid.
