Sorry for the late response...I was out Fishing!
Yes, my tabs are 12"x9". I have talked to Lemco, you are correct...the Orange wire controls an auto retract for the actuator. If you have LED lights on your trim tab switch, this is not necassary as long as you remember to return the retractors to neutral. My Trailer and lift, are not impacted by the trim tabs, so I will most likely disconnect the Orange Wire. It's more of a preference, when you arrive at your favorite fishing hole, turn the motor off, and now you have the loud winding noise from the actuators. I don't know, maybe I will just get used to the noise.
Thanks for the Response.
