I have a 2001 Olds Alero that I will be installing a Z2 with back up cam in a few days. I was wondering if anyone could help me out in telling where the reverse wire and VSS is. I searched around and used the website where you punch in the make and model or your vechicle but no one has ever installed a pioneer screen on this website!

Any help would be greatly appreciated!

vss--dk.green/white@ecm left of steering column

no listing on reverse just run it to taillamp assembly and tag it at the light

so what do i do? find the reverse light in the trunk and splice into that wire?

yup answered ur own question

Well, which wire do I choose? There are two coming from the reverse light in the back!
