I would say just plug in the one harness you have and see what works. Sometimes the factory will have the extra harness there in case there is an option. Maybe there was a radio with a cassette and the extra plug was for a 6 disc changer. Better yet unplug them one at a time with the old radio and see what does or doesn't work.

 

it's trying to spit up CDs. The flap is down

 

I like the unplugg one time theory, ill give it a try

 

If going aftermarket you only need the one connector.

 

Hiding amps:
You can place your amp almost anywhere, just try to keep it away from peoples feet and in a cool dry place in your truck. With some custom work you, finding a place to put a set of amps shouldn't be to hard.

This looks great, I wished I saw this years ago. Do you have the measurements for the wood? I am thinking of relocating mine back there and had no idea there was that much room.

Oh, and where are you grounding to back there?

 

Seat frame mount is a good place to get a ground but I just use a self tapping screw into the floor

 

I am trying to install an aftermarket stereo in my truck, and I cannot find the correct harness. I have a 2000 SuperCab with the Cassette deck in the dash and disc changer between the front seats.

There are two harnesses and a radio antenna going into the stock unit. I have not been able to find the correct harness adapter to connect to the two leads. I also cannot find pictures of the same setup. Please help!

 

Pretty sure that the disc changer harness won't be used with your new install so you will only have one to use.

 

i have a 2002 ford f150 lariat supercrew 5.4 triton fx4. it had a radio/tape deck that controlled the cd changer in the center console. a vcr under the back seat and a fkip down tv in the roof. also as i started removing the extra audio video i found a radio antenna booster that i think later produced smoke.
so... i've already been through the double din large screen install on another f150 may it rest in peace, and an e250 with the added hassle of software issues in another language.
this is my first truck that came with this many bells and whistles and i'm going with one of the 10" android tablet radios.
so i got it all fitted for the truck and wired in and i loved it, even though its very poorly programmed and most of the important settings are locked, in another language, or you would need a programming degree to navigate.
until i shut the truck off. when i took out the key the radio stayed on like the old one, but when i opened the door it still stayed on, and the windows kept power. the auto down window relay still worked so i switched the relays to see if that went bad. same problem. since then while testing the first unit something smoked and clicked a lot when i turned off the truck and radio was still playing. not sure if it helps but the station playing was in the frequency of the booster i found in the dash. i think the booster is where the smoke came from, not sure about the clicking though. i'm thinking a relay back there went but not sure where to start. there are so many.
please, any help would be appreciated. first time post.

 

i believe the second plug is for steering wheel controls. it was in my 02 explorer. the explore didn't come with wheel controls but when we needed to replace the shifter it was cheaper to get a whole steering column from the junk yard. i think it was from an expedition. the wheel had controls and worked.
