Couple of questions. What's the difference between non heated eliminators and late model heated sensor eliminators? Why is there a different color for front and rear in the late models as well?

IIRC from changing my header pipe the different colors are so they get installed in the correct position.

Alignment tabs are different between F&R housings.

That's what I thought too but wasn't sure. CRAFT syndrome is slowly taking over.

Been there,  done that, got, um, wait- what are we talking about?

That would make sense. So, the only reason is to keep ECM reference for front and rear in the wiring itself? No other differences regarding the resistances between front and rear eliminators, otherwise, just connector tabbing?
