I'm replacing the rotor, calipers and hub on my 2000 Ram 2500 5.9 V8 and the new hubs have a speed sensor line from both hubs but the old ones I'm replacing don't appear to have this feature. Also I can't find where this connection would plug in. Does anyone know where this plugs in or is it something I won't be able to see until I have everything apart ?

 

You likely just have rear wheel anti-lock, so, no sensors in front. If the non-abs hubs are cheaper, swap 'em out.

 

Can I just install these and dog the wires off ?

 

Sure.
