Hi guys, question for you all! I have a 1998 735i that I want to fit a detachable towbar onto, I've got hold of one off a '97 750i but what I could do with is a diagram of said towbar to make sure that I have all the bits I need... Apparently it was a factory fitted from new jobbie, it looks like it's just a shaped plate that bolts onto the chassis behind the bumper, I know I need to cut the bumper & buy a cut out cover (£21 from Coopers Norwich, not bad ) & that they plug into the loom behind the rear lights but are there any more brackets/strengthening arms that should go on it? Also, I think it's s'posed to have a relay fitted for the check light control, any ideas where this goes & what it looks like? :confused any help gratefully received!
