How do you tell which relay is right for your wiring harness? The answer is below:
A completely new wire assembly will work with all of the CMC jack plates and trim & tilts that we have been making since 1990. The 7122 40-amp relay has no skirt. The 7312 & 7493 have a skirt. The 7493 has replaced the 7312 relay and will plug into the same socket. The 7493 will not plug into the socket that was designed for the 7122.
