I would like to fit a tow bar to my 97 850 r estate....The mechanical bit is not a problem as I can get a bar from a scrap yard. The bit that concerns me is the electrics (sparks) . With these new fangled ECU gizmos and things on modern cars I assume wiring in extra lights is not so easy as it used to be in the happy days when you could splice straight into the wiring loom and keep your fingers crossed. Do any of you wizz's out there know how to do this?? ttfn....Alistair
