Sync3 upgrade using PNP cable

Just had a little mess about whilst a wait for a reply but seem to have issue with the bluetooth and no voice guidence when using satnav... Can't turn volume up so it might be fine once I get the front panel to work

Is it literally 2 wires that need to go to that front fascia?

I think I could just do it but not sure how to connect it to the front connector.

Also connected the reverse camera today although fit is good, the angle isn't quite right and facing down too much and looks terrible at night... Might have to upgrade the reverse bulb to led 🤔 Also guide lines not working 🙄

Going to have to find another, luckily this was from amazon prime so no issues with returns.

You should be able to turn the volume up from the steering wheel controls I would have thought. And yes, literally 2 wires from the small screen connote to the front Facia connector

Found a new car to download the as built data and did the changes from foccuss built steering column controls still do not work. 

Unless I am doing it wrong? 

I did read bcm, change the values. Write to bcm, read ipc change values and write to ipc. 

I'm pretty good at this stuff but the instructions aren't super clear. 

Still waiting for reply from China. They asked for a video so that's been uploaded but honestly it's so close to being finished which is annoying lol. 

Need to find a USB hub as I don't think the original one will work. But not sure. I only need for Android Auto not Carplay

Weird how the new harness did have a socket to insert the 4inch screen connector in to... bizarre.

So, what I’d do now is pop the pins with cables still attached out of the screen connector and they should slot right in to the Facia connector, I think you may only have to split one of them onto an existing cable on the Facia connector. From memory there’s a spare socket I think for one of the pins.

Just looked at this again, pin4 to pin7 is fine it's the yellow cable but to pin5 to pin4 is is the spare socket I don't have any pins to put in there so would I need to order some or is there another way?

Sorry on the delayed response. With pin 4 on the FDCIM connector, i simply popped this out and unravelled the tape to give me more play and expose the wire. Then spliced that on to pin 7. I did the same for pin 5 to pin 4 except this time, i revealed more of the cable and this allowed me to route and push the pin into the blank slont on the front panel connector.

 

So in short, 4 to 7 requires a splice and 5 to 4 you are literally removing the full pin and cable and then placing it in the blank slot on the front panel connector. 

Also, regarding the steering wheel controls, i honestly think its the harness you've purchased. It just worked straight away for me but i did the 'dirty method' and manually pin swapped and spliced without a harness. Obviously your method allows you to go back to sync 1 relatively easy but the original method mentioned and used in the stickied forum post is sort of permanent... unless we reversed all the pins swaps and splices made lol

Hope this helps!

There's some great info in here that makes me more confident to do this. One question, how are you splicing? Are you managing to get two wires into one pin?

Few ways you can do it really - What ever works for you!

1. Remove a bit of the plastic on the wire itself to exspose the copper wire and then solder on to there to get a secure connection then wrap with a bit of electrical tape to ensure no shorts.  (Most reliable method and secure, i did this)

2. Remove plastic on the wire and then wrap the other wire arround it tightly then secure with eletrical tape. 

3. Scotchlocks (can never spell it right lol) - Not a fan of this method as they have to be the correct size and sometimes don't cut in to the cable all the way and can come loose down the line if not tight enough and not the correct size for the guage of wire being used. Although, quite a lot of people do have good success with them but then on the other hand the amount of times i've seen people with stuff not working with scotchlocks being used is quite high also 🙂

 

What ever is easiest for you really!

That's good to know. When I worked retrofitting cameras onto buses we always used method one but pulled the pin out and got some heatshrink on there, obviously it was a lot easier on buses rather than trying to do it in a car 🙂

Here’s a harness I made for a friend a while back to do a sync 2 or sync 3 upgrade.

Just swapped the pins around on the harness and only had to splice a few cables.

Hahah brill! Yeah heat-shrink tubing is Brilliant stuff, I love it! Sometimes you can get away without solder and just wrap the wire around then heat shrink over it and it’s really tight!

Yeah I'll have a look when I do it, I do like a nice solder though 🙂

Quick update, return has been approved and will be getting full amount back. Just need to pack it all up and go down to post office.

 

This leaves me with 2 options, either sell the sync3 and put my old one back in

Or find a kind person on here who can help me out with modifying the original cables 😉

Stick sync 3 in, buy a un-made harness and swap the pins over on the harness and then it’s 90% plug and play. Well worth it. Familiarise yourself with the guide already on the forum. You may have to splice or route about 5 cables. So easy :)

So after returning the cable I bought first I got another one advertised as Option b from a different seller. 

I checked with the seller first and sent loads of photos over and they confirmed it's correct cable. It has the connector for the front panel which plugs into the fdcim connector. 

However not quite sure what these yellow and green cables with the pins are. I tried connecting them together green to yellow as one is male and the other is female but nothing. 

Contacted seller should get a reply tomorrow. Until then I decided to update to SYNC 3.4 latest version with latest F9 maps. 

Oh the steering column controls work fine now too.

All sorted they sent a quick diagram where the pins go. All of working and fitted. 

Just have small issue with sync 3.4 screen gone dim when car is on.

Also randomly get navigation fault when I turn on so not sure if the GPS antenna is bit slow to start. 

Just need to see if the original USB hub work with android auto don't fancy buying a new one and don't need Carplay

Aliexpress 4" TO 8" PNP Conversion Power Harness Set for Ford SYNC 1 2 to SYNC 3 Upgrade Harness Wire

https://a.aliexpress.com/_mNHC4TZ

It's not cheap but cheaper than buying from the US and it actually came quick the standard free shipping. 

I know a lot of guys have done it using the guides on here but I couldn't get my head around it and couldn't find anyone including to autosparks locally to do it. 

Another one who was a mobile car audio specialist flat out refused and said it can't be done blah blah and only Ford could do it even when I sent him the link on here.

It was just over £150 with customs fee... Easy to say £40 harness but no one selling em and time and labour for someone to help would probably be much more. 

Either way I'm happy, could have bought a pioneer or alpine screen but wheres the fun in that.
