Hello all,
With the help of Sirrus here I was able to successfully install a new stereo and speakers in my 1987 Grand Wagoneer so I thought I'd walk through the process.
Here's a link to the Polk speakers:

Be sure to get the speaker harness with them. Crutchfield will ask during check out for your car and they included Jeep harnesses for free when I purchased but here's a link to them just in case:

Here's the car side wiring harnesses. There's one 8-pin female for the speakers and one 8-pin male (6 pins used) for the power. The metal pin is for the antenna.
I was able to use the old cradle from the OEM stereo. Be sure to center the front part of the cradle as it can tip up or down. It needs to be straight for the stereo to sit right.
This is the included new stereo harness:
This needs to be wired to compatible 8-pins that you can find here:

At first I tried to use the old 8-pins from the old stereo but the wire was very brittle and when I tried to strip it 1/2 the time the copper wires broke off leaving just a few stands. I felt it was better to start new.
The Clarion has RCA outs as well as connectors for power. It's a lot of wire to stuff behind the stereo once installed:
