Just found your post searching how to eliminate the US Automatic photo eye sensors to my Ranger duel swing gate and joined to be able to reply to your answer with questions. Can you provide a little more clarity for me to understand? What do you mean by saying "between" with "Wire the NO (normally open) pins "between" control board pins 7 and 8. (There is no slot between 7 & 8 on the control boards J2 terminal pins 1 through 12 pins. Using the 12v automotive 5 pin relay am I understanding correctly that you're only using the two relay coil pins (which are the power & ground pins) wired to the J2 pins 12(photo eye power) and the other to one of the J2 terminal ground pins (2 or 7) AND that there is no other wiring from the 5 pin relay to the J2 control board. Meaning the only wiring done is from the two +/- coil pins on the relay to the control board J2 terminal pins 12 (photo power) and ground pin 2 or 7. And perhaps you're saying "between" is placing a bypass wire on the control board J2 terminal pins from pin 7 (common ground) to pin 8 (photo eye closed direction N/C Input)? If this is the case, why a "5 pin relay if you're not using the other relay pins for normally open to normally closed? Can you use a 3 or 4 pin relay for the same behavior? Please help me understand this. Also, does this mean I can then completely disconnect the wiring from the photo eye to the control boards J2 connection pis?
Thank you!
