FABRICATION REQUIRED
This is a universal kit so a mounting plate and rotor will need to be fabricated. In most cases, the two pickups need to be mounted 180° apart. The magnet will need to be installed to the rotor in line with the pickups.
WIRING
Clean, well crimped or soldered connections ensure reliable operation of the ignition system. Before making any connections, inspect all wires and their routing. Figure 1 shows the proper connections for the MSD Trigger Pickup Assembly.

SETTING THE TIMING
In order to set your timing your mounting plate will have to have slots in order to rotate the plate clockwise or counterclockwise. In most cases moving the plate counterclockwise advances the timing and clockwise retards the timing. This will also depend on the rotation of your engine. The pickups are also slotted to equalize timing between cylinders.
MAGNET
Note: The rotor must be made out of aluminum.
In the rotor that was fabricated a hole will have to be drilled approximately 1/4" in diameter and 1/4" in depth. The magnet should sit flush with the outer diameter of the rotor, with marked side of the magnet facing out. To secure the magnet in place use JB Weld or equivalent epoxy.
