What type of wiring is necessary on the back of these? Are you just plugging in the antenna and the factory plug or is there more involved? I don't have any aftermarket speakers, subs, or amps. All factory.

You buy an adaptor to go from the factory radio plug and you match the colors on the harness that comes with the unit and use the red crimp butt connectors to splice it together. Add some tape and Plug the sides in to their other end. The radio at least in my truck doesnít require an adaptor to work. It just uses the factory plug style to plug in. The particular one I have has the usb plug in the back and comes with an extension cord which I run straight down and bring it out the bottom of the dash above the trans hump and hang it on the dash hook. Itís super easy. You also need the correct dash kit. I usually go to best buy for the kits because they usually have everything in stock and can explain it to you if you have any questions. YouTube is even easier. Factory radio removal will require a special tool which you can probably make out of some mechanics wire or buy them as theyíre super cheap.

Tractor supply didnít have the all in ones. I also tape each wire individual then tape them all together to make a sort of loomed harness. I soldered the last harness together and taped each wire but Iíve moved 4 times since then and have no clue where my solder gun went.

Also these units that can play dvd want you to run a wire over to your e-brake switch. Instead of doing that you can buy a micro switch for $7 or so that way you donít have to mess with the e-brake to play videos. Higher models with Nav built in have an internal override where you hold your finger near the bottom left corner of the screen for around 10 seconds. Then youíll be able to edit nav directions or watch videos without messing with the e-brake and technically you can watch videos while driving also.

Oh trust me I know. It's a pain sometimes to break out the flux, gun, and solder. I like that we have a big box of them and all you have to do is grab crimpers and a butane lighter and it's a solid connection that will last years and be reliable. Heck that is how I made my entire wiring harness when I did my Cummins swap. Still going strong 10 years later with no issues.
