90-92 = NO start relay, ALL the starter solenoid current passes through the clutch safety switch . That is why it is especially important on 90-92 MY Z's to fully depress the clutch BEFORE turning the key: prevents arching on the switch contacts.

However, in 93-95 Z's the starter circuit was changed to include a seperate starter relay to handle the current. The clutch safety switch now only switches on that starter relay.

However, a relay can be added to the 90-92 Z's between the clutch safety switch and the starter solenoid, a relay like the 93-95 Z's have to carry the high current load of the starter solenoid. (So, having a 93-95 Z you DO NOT need to install an auxiliary relay!)

Dynomite included the relay mod procedure in SOLUTIONS (sticky).
