2002 epedition

Hey all, I am new to the forums here and already I have found out a lot of useful info. I searched for info on my questions but came up empty. 1. I am having a hard time finding a wiring harness/mount for my 2002 Expedition. I see 99-01 and 03+, seems to always skip 2002. When I did find one, it said for systems without the Mach (which I have). Will any others work? 2. The last owner did a hack job on the system. The stock 8" sub was taken out and the factory box made larger for a 10" sub, then turned in with no sub. Even the factory amp is toast so I have ZERO bass in the truck. It also had the Visteon system installed. I have since taken down the VCR and plan to run the video cables from the monitor to the head unit for a future DVD player or something. On to the question. Behind the stock head unit, there are 3 plugs. 1 appears to be pwr/gnd/speakers/etc, and I think the other one is for the 6 disc cd changer? So what would the 3rd plug be? I have pictures at home and can upload later on. 2b. Can the stock 6 disc cd changer be retained at all with another head unit? 2c. On some of those 3 plugs, it seems they ran other wires from them, or were reconnected at some point. Like I said it looks like a hack job but I am 99% sure the main plug is intact its just the 2nd/3rd plug I am not sure what they are for. 3. I am installing my old system from another vehicle that was wrecked. Its an Alpine cd head (model unknown at the time). My truck has a large opening and I would love to eventually install like an Eclipse or similiar head unit with the lcd screen (not the flip out type). Of course, Crutchfield says they will not fit; probably b/c it may take some modification. Has anyone installed one and what issues did you run into? It seems that maybe clearance in the dash would be in the only issue but I see some plastic that can easily be done away with. 4. Since I removed the Visteon VCR from the rear of the truck, I know have a nice 12"x11" square hole in my headliner. Any ideas on what to use to cover it? I was thinking about some heavy duty cardboard and some tan cloth to match?? Thats about it off the top of my head. I will be doing this in the next week or so. Thanks!

Doh, should be Expedition LOL, cant edit post.

Ok at home so I can show some pics:This is the back of the stereo where you can see the 3 harnesses in question. Also, where you see electrical tape close to those harnesses is where I said it looks like something was rigged. And, looks like I was wrong about the main harness being cut into. There is also an antenna splitter, is this normal? http://crazy-world.net/photos/albums/02expedition/IMG_0365.JPGForgot about this, what is this for? It was just laying behind the dash. http://crazy-world.net/photos/albums/02expedition/normal_IMG_0367.JPGAnd finally, the old Visteon VCR I took down: http://crazy-world.net/photos/albums/02expedition/normal_IMG_0370.JPGThanks.

Update: Thanks Mods for fixing my posts :) I found the proper harness and mounting kit that worked in my truck. Installed my old Alpine and sounds 10x better already. I cant understand why anyone had cut into the original harness... Seemed like 1 lead to each speaker was either cut or striped. I soldiered everything back up properly. Anyone have answers to 3 & 4? Thanks.
