Today, I got the horn working.
Thank you to you guys for the advice and the pics. They really helped. Got the wiring from under the radio, found the cut light brown wires, spliced them back together and HONK! It works!
Also got the OEM carpet floor mat for the 2nd row seats and it fits just right.
My work has finally calmed down so now I have more time to work on and get the next things done on my to-do list.
1. Steering wheel (w/radio controls) swap
2. 3rd row bracket/bolts install and seats
3. Center bench seat install.
4. Get tire installed on the spare PPV rim. Rotate/balance all 4 tires.
