OEM Meyer Motor Solenoid part#15370. They do not need to be mounted on steel anymore. The White wire from the harness goes to the S terminal, and the I terminal must be grounded. Scroll through pictures to see. September 2022 - Per Meyer Service Bulletin 281, they may substitute 15370A in place of 15370. The I terminal on both must be grounded for it to work properly. It would only be older systems that are affected since the 22691, and 22691S both have a ground wire in the harness so no big deal. An old E-47 with toggles you will need ot ground the I terminal.
