/diy/ - Do It Yourself

can someone help me interpret this wiring diagram? it's for a garage door opener, I'm trying to bypass the laser sensors because one or both refuses to let the door close. I can open the door in the mornings, but have to close it manually, so what's the point?

there's a frustratingly small amount of information on bypassing the laser sensors for some reason, maybe Big Garage Door is trying to suppress it for some reason. Anyway, I read somewhere that I can put a jumper wire in at some point in this and it'll bypass the circuit, but I can't figure out where to put it from this diagram.
