Hi all !, just bought a 05 plate CR-V Executive, need help reguarding tow bar electrics. Car has no towbar fitted at the moment , but i wish to fit 13 pin electrics as my caravan has this fitted. Would it be advisable to buy the 2 looms : 08L91-59A-612N and 08L91-59A-512S ? Then join these two into a 13 pin plug ? Also will the lighting circuit require a HD flasher unit , and what turns the reversing sensors off when the caravan is connected ?
