So I've got the code that my front left speed sensor is shot and a visual inspection confirmed that the connectors have simply fallen apart/disintegrated. I got a new wabco cable with the ends you have to wire into the slabs. Should I be following the existing cable to the slabs and wiring there or do I need to wire it into the slabs somewhere else? and how?

 

iirc. the replacements do not have plugs just a wire that runs all the way back to the slab

 

yep, that is correct. unfinished wire that needs to get... I dunno... soldered in, or 'connectored' in? I'm not much of an electrical kinda guy. and I'm just not sure what I'll be looking at with the slabs.
