Hi - just want to add these to my old garage door openers. The old receivers broke. Looking for the document thats shows that wiring. The paper I have seems to only show what dip switch 3 off shows… for a light bulb and siren. I will be connecting the receiver to the physical button wires. rending the old physical button inoperable, I assume. But that’s ok, because I plan to just put the remote you provided on the wall and use home link in the cars. Thanks in advance.
Also amazon suggested the 12v power adaptor when I ordered the receiver. I see this is labeled 5v. But 12v is ok as well?
