I found the following relay which should work as a replacement for the stock Westy Kissling relay. I have not installed it yet, but will likely order as ours is "sticking" a lot and causes a voltage drop across the relay. Quickly "exercising" normally gets it working, but only for a period of time. It would require a "jumper" cable/bar like the existing relay has.

Another one that another Westy owner used:

Now that we wired our dc-dc charger via the relay, we notice the "sticking" much more frequently (the charger often only gets about 11V when the car is running because of the relay) then if we were only using it for the Air Conditioner.
