will this harness protect my new sony CDX-GT55UIW from destruction when I power up? 1991 Navajo

I used this on a 95 mustang with mach 460 sound system. For itt to work correctly you need a stereo with 6 channel pre.amp output.As far as protection this is only designed to make the connection to your new stereo without cutting your factory harness. But if wired correctly I see no reason it could harm your stereo.

Will this work in my 99 mustang base model

The best I can say is, maybe. I had an issue with installing it because there was some kind of other adapter needed and so I ended up taking it to a shop for them to install it. I ended up not using this item at all.

I'm trying to replace the OEM CassetteRadio on my 1993 Lincoln TC w/ premium sound. New radio only has 2 RCA out. Will this work for me?

As is it would only allow 2 speakers to play. You could possibly use something like the Pyramid RY6 1 Male to 2 Female RCA Adaptor to make all 4 speakers work.

Not even sure if I need them, yet, but... what kind of crimp caps/wire connectors would I need for these (in gauges)?

on my 2000 mustang/cd radio didn't need any connectors plug and play make sure you connect all blue wires makes your amp work
