Description

Rywire Alt-obd1-obd2 lets a 1988-1995 Honda or Acura chassis plug into a 1996-2001 OBD2 alternator, a common need when a swap brings an OBD2 alternator into an OBD0 or OBD1 car.

Why This Alternator Adapter for Your Honda Swap

The Rywire Alt-obd1-obd2 is an alternator adapter that lets a 1988-1995 Honda or Acura chassis plug into a 1996-2001 OBD2 alternator when a swap brings one into an OBD0 or OBD1 car.

  • Versus cutting and splicing the factory plug: This OBD0/OBD1 to OBD2 alternator adapter plugs in between the chassis alternator plug and the alternator, so the chassis plug stays uncut and the change is reversible.
  • Versus hunting down a matching-era alternator: This OBD0/OBD1 to OBD2 alternator adapter lets you run the OBD2 alternator that came with your engine instead of finding an older alternator.
  • Pairs with the Rywire OBD1 harness: This OBD0/OBD1 to OBD2 alternator adapter is offered for the Rywire OBD1 Mil-Spec D & B-Series Tucked Engine Harness (B1-Milspec) when running an OBD2 alternator.

Best for: A 1988-1995 Honda or Acura OBD0/OBD1 chassis running a 1996-2001 OBD2 alternator, including builds on the Rywire B1-Milspec harness.
