Android car stereo install questions

1,196 145 June 12, 2021 at 10:33 AM Get Amazon coupons Coupons
First off, the parts:
1997 Ford F350
ATOTO S8G1A84SD [amazon.com] head unit
ATOTO AC-HD02LR [amazon.com] backup camera
27' Travel trailer
Beastron [amazon.com] 2.4GHz Video Transmitter and Receiver
Trailer camera

The Beastron is to save the cost of paying someone to run a signal cable the length of the trailer. The ATOTO camera connects a bit differently so that the head unit can power it, allowing it to stay on without being in reverse gear. Attached is my wiring cheat sheet. I'll start soldering once I get some confirmation that the connections look correct, so please check it.

If you want someone to try to review your wiring plan, you'd be better off posting in a car audio specific forum. Documentation for these Chineseium car stereos isn't always great.

As for soldering, I hope you're planning to make or buy a wiring harness adapter that adapts the factory wiring harness to the new stereo. There could be a few things that weren't part of the factory harness like a wire to sense if you're in reverse. That's old enough there probably isn't a CAN bus connection for the stereo or steering wheel controls to adapt.

If in doubt, try to test that you have the right wire. I knew someone who's car stereo install at one of the big outfits went awry, they managed to screw up wiring for turn signals, wipers, etc. in the process.

Thanks. Where the text file says black or gray vehicle harness it is referring to a Scosche FD02B. I normally would find a more specific FB group but I'm finishing a ban. The documentation with that deck is surprisingly good. I've seen worse (and certainly less) with name brand phones.

If you are going to wire directly to the main wiring at the ignition/key (I would not recommend wiring here for a stereo) then make sure you are putting fuses in-line in case of wiring shorts. You don't want a small wire burning up because the main ignition wiring can handle quite a few amps and likely won't blow their fuse while the smaller stereo wiring will likely melt/burn.

I'm on mobile right now and it's a bit hard to decipher your wiring schematic. It's not entirely clear where everything is going (could be formatting on my part).

When soldering, make sure you know how to make a good solder joint (I.E. not a cold solder joint). Back when I did car stereo/alarm installs there were quite a few 'professionals' that did not know how to solder correctly. Also, make sure you use quality electrical tape or heat shrink. I like 3M super 33 electrical tape (very stretchy and heat resistant - good in the car environment).

I had a chance to review on a computer. Your diagram makes much more sense now.

A few more comments:
1) What is the Furrion power adapter you are using? They make all sorts of adapters.
2) Are you using 2 backup cameras that are the same? A truck backup camera and a trailer camera with the trailer camera attached to the RF transmitter? Depending on how the head unit handles the inputs, you may want to use the front camera and rear camera inputs.
3) You aren't showing power hookups for one side of the RF receiver. What is your plan here? Hookup the same with the head unit power?
4) Are you positive the 'floating display' will clear the recess of the F350 stock stereo install?
5) Are you using the 'Scosche FD02B' for the harness to install or hard wiring to the existing wiring by using that as a guide? Like jkee, said, I'd recommend having the harness instead of hard wiring.
5.1) I would use this harness for powering the RF receiver as well (assuming it doesn't draw too much power [doesn't seem like it should]).
6) My previous comment on soldering still applies. Make sure you know how to do this correctly (not hard - many good tutorials online - like this one [youtube.com]). I recommend having solder with the flux built into the solder.

The head unit harness is fused. I don't have much soldering experience (I use a $10 iron instead of a new TS100 because I have no idea what temp to use). I wonder if my soldering explains why the radio I put in my moms car factory resets a couple times a year. I ordered this PPCLION heat shrink [amazon.com]. We shall see how it works. What length should I use?

1. The trailer has a powered (from the running lights) mount for a wireless Furrion camera already installed on the back. I have this adapter kit [amazon.com] that is working so far. I haven't yet tested to see if the RF kit is powerful enough to get from one end of the trailer to the other.
2. No. I may use a spare camera for the trailer. I don't know much about it, but it likes the RF kit. It appears that VIN is considered an Aux input and where I'll connect the trailer cam because though the front camera input is seen by the same app, it is designated for the dashcam accessory. I am using the ATOTO camera for the truck backup cam though because it can be controlled by the reverse lights and easily overridden to stay on during difficult maneuvering. I think I'll even be able to split screen the cams.
3. I'm not showing power input for the RF receiver because it hasn't been determined yet. I'd like to mount it to the truck, but I don't see anywhere that is out of the weather and not surrounded by steel. The deep cycle batteries are mounted in a plastic enclosure on the tongue. I'm thinking of mounting it inside that with a switch and fuse directly to those batteries. I would then run a short RCA cable from there to a connector on the truck bumper (I'll consult my brother in law about that. He's running a a dual wired cam kit). I'll throw a layer or two of loom on that for some protection.
4. I haven't tried it with the actual unit yet, but I made a mockup from their given dimensions and that fit quite well.
5. Plug ends of FD02B go to F350 plugs and wire ends of FD02B are soldered to their counterparts on the head unit harness. 5.1 As mentioned I'll probably pull the receiver power from the trailer deep cycle cells.
6. I'll take a look at that, thanks!

Fits (almost) great. Between the short FM antenna, the various connections, harnesses, and cable bundles for the GPS and wifi antennas it was difficult to stuff inside the dash. As the pictures show it looks great once in though. ​The cables are one foot aux and USB extensions because I knew the front ports would be difficult to reach.

What matters is that it works and that you are happy with it. 👍

There are antenna extensions available and it's possible you could locate the GPS antenna somewhere else (depends on cable length - may get better reception as well).

It's also possible to put your USB and aux connections in 'blank' spots in your dash, but that might be more work than you want to tackle.

I had to get it functional before Thursday when my dad had reservations at a campground 90 miles away, otherwise I'd have ordered an FM antenna extension (still might). Had to postpone the trailer camera and the truck camera isn't yet working right either (can't get guide lines nor activation by reverse gear. It is working when the app is manually launched). Unfortunately he discovered yesterday that his hazards and turn signals aren't working. Of course the flasher relays are buried in a cavity near the radio. I did some digging and found this https://youtu.be/g6ZnneC7lCM. My dad can't watch it on his flip phone but I guided him far enough to find them. He also discovered this mess (none of which is my doing). As for the external cables, I'm happy because it puts those ports right on the end of the dash shelf. I'm also happy with the wifi and gps antenna placement. I just wish their cables weren't so long because they had to be bundled and guided into the cavity, hopefully out of the way. It was very tricky, but I got the FM antenna connected too.

Oof on the mess. Someone surely didn't know how to organize wiring when they were doing stuff. Kind of looks like an alarm install, but hard to tell for sure.

As for the relay, some of the comments in that video mentioned pulling the cup holder for easier access.

Usually easiest to get the reverse at the rear light, but there are wires up front as well. Try this discussion - https://www.ford-trucks.com/forum...ost3592541

I'm not sure if your radio has guide lines or the camera does. Sometimes there are some wires on the camera that need to be cut or put together to enable guide lines.

On this it's the radio that overlays the guide lines. I'm told the turn signals just got fixed. Tore off the "multifunction switch", aka turn signal lever and cleaned all the contacts. The alarm is stock, but it has a (non functional) remote start. One of the displays on the floor is the fuel level for the three tanks (two stock and one aftermarket. 130 gallons total. Previous owner was a long haul trucker). It also has an Edge Tuner. First owner added trick lighting and took it to shows. Any of those could have something to do with that mess.
