Hi I was wondering if there is anyone out there who would know how to wire an alternator off a 3B Diesel motor on to a B motor. Everything fits but I am not sure about the wiring. The vehicle was originally an Fj40 but this is the second diesel motor that has been in it. So it has a few extra things under the bonnet that aren't needed which makes it even more confusing. I would appreciate any help anyone could give me to avoid EXPENSIVE trip to Auto elec.
