Q
Will this allow me to keep my bose speakers in my 95 camaro z28 with an aftermarket head unit?

A
Yes that is the wiring harness we recommend to interface an aftermarket radio with the factory Bose system in those '95 Camaros. We include it (along with dash kit and antenna adapter) at a discounted price when you purchase a radio. If you have questions, or want help selecting a new radio, you can connect with one of our friendly product advisors for live support here: https://www.crutchfield.com/I-rET1c290/S-SUliZgSTXG7/support/ContactUs.aspx

Yes, I just did a swap on my 1993 Z28 with Bose speakers and everything works great. Also, if you're looking for a new head unit, don't get a full size double din, you'll want a slim double din to fit.
