OVERVIEW
The procedure involves removing the three existing Bosch alternators, their corresponding brackets and
harnesses and replacing them with a pair of DelcoRemy 55SI alternator.
The alternators require new brackets and harnesses. A boost regulator and corresponding harness is
also added in the main power compartment. Reprogramming the vehicles’ MUX program is required.
First time users should read the procedure before starting work on a vehicle. Best viewed in color.
