Mopar Performance Electronic Ignition Conversion

With

Vacuum Advance Distributor

Part numbers P3690426, P3690427 and P3690428

This information pertains to Mopar Performance Electronic Ignition Conversion Kit and is actually the HTML version of Instruction Sheet DCF-194. This info will refer to the package for vacuum advance distributor, wiring harness, electronic control unit (ECU), ballast resistor and wiring connectors. Installation is simple and can be accomplished with basic automotive tools. It is suggested to read through these instructions at least once before beginning the installation. These instructions are divided into various sections. The first section pertains to all installations. The next four sections pertain to the style of ignition system being replaced:

• Point Type (used up the early 70’s and most of here will use this one)
• Chrysler Electronic ( used from the early to late 70’s)
• Lean Burn/Spark Control Computer (used from mid’70’s to the late 80’s)
• Logic Computer Controlled (used with all TBI fuel injected vehicles)

The fifth and sixth sections deal with Start Up and Tuning. A short Trouble Shooting section and additional sections on wiring Street Rods and wiring vehicles without existing wiring harnesses is also included. Tools required for each installation are listed at the beginning of each section. If any troubles arise, call the Mopar Performance Tech Hotline at (313) 853-7290.

NOTE:
THE CHRYSLER FUEL INJECTION SYSTEM REQUIRES A SIGNAL GENERATED BY THE ORIGINAL EQUIPMENT DISTRIBUTOR.
TO INSTALL THIS KIT, THE FUEL INJECTION SYSTEM MUST BE ELIMINATED.
THIS IGNITION KIT WILL NOT OPERATE THE FUEL INJECTION SYSTEM USED ON CHRYSLER CORPORATION VEHICLES.

For All Installations

Additional Tools Required:
Distributor wrench
.008" brass feeler gauge

1. Disconnect the negative (ground) battery cable
2. At the coil, disconnect the wire leading from the negative side of the coil to the distributor
3. Note the location of the number one spark plug wire on the distributor. Disconnect the spark plug wires from the spark plugs and coil. Remove the wires from any wire looms or retainers
4. Disconnect the distributor cap hold down clips, remove the distributor cap and spark plug wires together. Set them aside
5. Note the location of the distributor rotor. Carefully mark the location where the metal end of the rotor is pointing by placing a piece of tape on the engine of firewall
6. If the distributor being replaced is equipped with a vacuum advance canister, note the direction the vacuum advance canister is pointing and disconnect the vacuum advance hose
7. Remove the distributor hold down bolt and hold down clamp
8. Clean off the area around the distributor opening
9. Carefully remove the distributor from the engine. Rotating the distributor back and forth usually helps
10. Disconnect the distributor hold down clips on the MP distributor and remove the distributor cap
11. Check the air gap between the distributor pickup and the reluctor (see Figure #1 on page 8). The air gap specification is .008". This should be checked with a brass (non-magnetic ) feeler gauge. Set the air gap if required
12. Rotate the distributor shaft by hand. It should rotate freely, but it is normal to feel "pulsations": as the reluctor prongs pass the pick up
13. Check to make sure the distributor’s O-ring seal is in place and lightly coat the O-ring with oil
14. If your old distributor was equipped with vacuum advance, hold the new distributor so the vacuum advance canister is in the same position as it was on the old distributor, as noted in step #6, and carefully set the new distributor most of the way into the block. It may help to slightly rotate the distributor back and forth while wiggling the rotor. The distributor should meet the block’s surface
15. Reinstall the distributor hold down bolt and clamp. Just snug the bolt, do not tighten. The distributor should still be able to be rotated with a little effort
16. Reinstall the distributor hold down bolt and clamp. Just snug the bolt, do not tighten. The distributor should still be able to be rotated with a little effort
17. Reinstall the new distributor cap

Proceed to the section pertaining to the type of ignition system being replaced.
