Hi Everyone I just bought a 52 plate Carry Pick-Up with just over 7k on the clock and the original set of factory fitted tyres ! Now i need some advice ! ! ! I want to fit a tow bar and SOME suppliers tell me i need a 7 pin realay in the system! Do I? I would like central locking. Can i buy the new parts to convert the manual locks? would the wiring already be in place on the loom behing the door cards? will other suzuki lock motors fit? (my son has a duff vitara)
