The remote locking has just stopped working in my Lexus is 200, the remotes still blink with the red led and the central locking still works from the drivers side door switch. I've also checked the fuse in the passenger footwell and that is fine too. My last option is to fit an aftermarket remote locking kit but that is turning out to be a real headache!! I found on another members feed about connecting directly to the circuit board in the drivers footwell but still can't work out how to do it. Can anybody help!!

I've just joined the 4 wires as stated at the top directly onto the circuit board but need to know how to connect the wires onto the remote control for the alarm? Any ideas anybody?
