  • Trailer socket wiring

    I currently have the genuine Toyota bar with 7 pin trailer plug and harness on my Crusade. I'm about to buy a caravan that needs a 12 pin socket on the vehicle and I see that Narva has a socket that incorporates a reed switch that disables the reversing sensor. I've found the reversing beeper particularly annoying when reversing my sons motor bike trailer. The Narva socket reed switch is either normally open or normally closed depending on the vehicle. As always there is a wealth of knowledge on this forum so does anyone have any experience or advice on this topic that I could benefit from?
    Cheers Graham

    is it factory fit park sensors?

      there is no factory wiring diagram for reverse parking sensors so it may have been an afterthought. you would think that with a factory camera you wouldnt need sensors as well. All you can do is find the power switch or fuse for the sensors and switch them off using a relay , triggered by the reed switch.
