The number of wires in a clock springs are dependant on the features on the steering wheel. All modern steering wheels have horn & airbag but base models may not have a bunch of buttons as compared to upper spec models so there may be a difference between base and up
er spec models.
But if you have a Calais V8 and want a new clock spring from the same year V6 Calais. I also can’t see that there would be any differences between the two clock springs.
