Secure the adapter plate assembly to the distributor with the 8-32 screws, plastic washers, and aluminum spacers as shown. (Note: It is recommended that a thread lock compound be applied to the screws before installing them in the distributor in order to keep them from vibrating or working loose.) Route the XR-i wire harness through the hole in the distributor. Install the supplied grommet over the wire harness and insert into the cable end of the distributor.
