Exciter Disconnect Harness Kit
Price range: $39.95 through $42.95
This kit is required to pass tech when using a battery disconnect switch with an alternator with a traditionally wired regulator. This also requires the Moroso 74102 Super Duty Battery Disconnect Switch. When connected as shown in the diagram, the disconnect switch will disable a running vehicle. Contents listed below.
Not compatible with many late model vehicles where the regulator of the alternator lacks an “excite” input and is instead controlled by the PCM.
Offered in 17ft and 20ft lengths.
