Here is how I did mine (mind you, this was 2003 and harnesses may have changed) -
MSD, Distributor, Coil, Voltage Regulator, Starter Solenoid, and Starter Wiring
·Thin red wire to ignition switch in place of white wire (splice red to white)
·Heavy black to ground
·Tachometer wire (#34 - gray) to spade connection on right side of MSD box (pull back through harness)
·Heavy red wire to starter solenoid – same side as battery from trunk
·White trigger wire not used
·Only wire used in harness is alternator wire (#39 to red) to voltage regulator BAT terminal
·Orange & black to coil (orange +, black -)
·Purple – green plug extension to adapter on distributor
·Connect fusible link (#27 – red/white) to starter solenoid - same side as battery from trunk.
·Connect #23 (purple) to “S” connection on starter solenoid
·Connect cable from starter to starter solenoid – opposite side as battery
