2007 Rav4 7pin socket

[Kerry1graham]

Hi after some help I to replace my 7 pin hitch lighting socket I have looked round but it looks like you to get the complete thing quite expensive. I've had a look inside the one on my rav looks the same as any other except for 2 grey wires that I think are for fog lights. Any suggestions for a replacement socket only would be great. also any advice on fitting a audible buzzer for the indercators when towing would helpful as it's a legal requirement.

Thanks Kerry
