Introducing the Rywire Main Relay Upgrade and Kill Switch Harness available in either an OBD0 or OBD1 configuration. Early vehicles get the Obd0 version, and 1992+ vehicles will receive the obd1 version. Obd1 version will work with obd2 vehicles as well. Simply disconnect and re-connect the isolation toggle switch if you decide to add that feature. These kill switch harnesses are ideal for those looking for an extra added protection of security for their vehicle. The Honda main relay is a very common failure point, and this harness allows you the ease of using a standard automotive grade relay VS the pricy and harder to source Honda specialty relay. Easy plug n play installation.
