Though most newer engines use electronically activated coil-on-plug ignitions, practically every car made before 1995 utilizes some sort of mechanical distributor. Newer electronic systems offer a more stable spark, increased durability, higher RPM and the possibility of more advanced digital controls for top-end applications.
#1Remove the plastic distributor cap from the distributor body by releasing the retaining clips around the base of its perimeter.
# 2Remove the rotor (the part in the middle that spins). Some have a retaining screw, while others simply pull off.
# 3Remove the points and condenser. The condenser is the small cylindrical object attached beneath the rotor. Follow the wire from the condenser to find the points assembly.
# 4Pull out the nut from the points assembly to separate it from the primary ignition lead.
# 5Follow the wire lead to the ignition coil and disconnect it.
# 6Push the wire lead up from the coil through the body of the distributor, and remove it.
# 7Feed the two wire leads from your new ignition module up through the hole in the distributor from the inside.
# 8Slip the supplied protective rubber grommet over the wires from the outside, and secure it into the distributor body. You may have to grease the outside of the grommet to slip it through the hole.
# 9Attach the supplied eyelet connectors to the outside end of the wires with a set of wire crimps.
# 10Attach the new ignition module where the condenser used to be with the supplied screws.
# 11Connect the black ground wire in the most convenient location on the inside of the distributor body.
# 12Connect the lead wire from the distributor to the ignition coil where you removed the old one.
# 13Install the round black magnetic shutter wheel at the base of the rotor shaft. There should be .030 clearance between it and the ignition module.
# 14Reinstall the rotor. This is a good time to replace both it and the distributor cap as cheap insurance against future problems.
# 15Now reinstall distributor cap. If you did not remove the plug wires, the engine should fire up without a problem.
