Looking for an isolation relay?

GM part # 10022620 or 10038949

You will not find a NOS isolation relay. They have been gone for a long time now. You might find a good(?) used one. I have had many requests to make a reproduction of this GM 10022620 and 10038949 isolation relay. There is the early and late style isolation relay. Internally they are identical and interchange (plug is different).

They come with the correct color wires. You cut off the old plugs that go to your original isolation relay and you butt splice/solder the wires to the factory wire harness wires and use adhesive shrink tube (included in the kit) to make water proof connections.

Potted in a black ABS plastic box and close to the size of the original.

The wires coming out of them are in the correct colors.  You cut off the old plugs on your wiring harness and butt splice them to the factory harness wires. Use the adhesive lined shrink tubes to make a waterproof connection.
