Don't know without checking. You need to take a continuity device and see what is happening with the new switch.
1....S2-18Y-Start / Purple This is your "start" wire goes to the start relay in place of normally yellow Hot ONLY in "start"
2....Q2-12BK-Accessory / Brown This is the accessory feed goes to the accessory buss in the fuse panel, hot in both "run" and "acessory"
3....J2-16DBL-IGN1 / Pink This sounds like "run" is hot ONLY in run goes dead during start
4....J3-14BR-IGN2 / Pink This for me is the ?? one check for sure that this is hot in start and if so jumper it to IGN1 above. This would have bypassed the resistor in start, but NORMALLY a GM based switch has no such thing, as this function is done by the GM starter solenoid "I" terminal.
5....J1-12R-Battery / Red Main feed to the switch from the battery.
