ronseal Posted February 19, 2017 Share Posted February 19, 2017 Hi All I know a few people have done this and i did find a previous topic but no answers to this question I have a 2013 Focus Zetec S as a second car.....and an unlucky mate who killed his 2015 ST with a bit of sideways action and a poorly placed tree....so i found myself with a lot of 2015 ST parts for very cheap so have decided to do the face-lift conversion on the Zetec S. I've so far completed nearly everything with the exception of a few niggley but easy resolved fitting issues its been smooth sailing but I've now come up against a problem which is the headlights don't seem to work, I downgraded from the 2015 xenons to the standard 2015 edge lights without the DLR's as i was hoping with the same as what was on mine these would be a strait swap but alas i was wrong .. anyone know if these need to be re-programmed or re-wired as they all plug in ok but wont turn on and display a dipped beam error, which makes me think ford decided to reconfigure the plugs.. is it as simple as popping out the internals of the plugs and swapping them about (i.e. different configuration - if so what is it ??) or is there something i'm missing any guidance would be greatly appreciated cheers Quote Link to comment Share on other sites More sharing options...
DJ_Andy_M Posted February 19, 2017 Share Posted February 19, 2017 There is a control module in the light, which talks to another module in the car. They are probably not compatible with each other. 1 Quote Link to comment Share on other sites More sharing options...
FourD Posted February 19, 2017 Share Posted February 19, 2017 Sorry to go off topic, but are you replacing the rear valance ? 1 Quote Link to comment Share on other sites More sharing options...
ronseal Posted February 19, 2017 Author Share Posted February 19, 2017 yep, rear valance & bumper was replaced with ST one... also anyone know where the module is in the lights, i have seen several 2012 / 2013 focuses with the later front end retro fitted so i know it can be done, just don't know how 1 Quote Link to comment Share on other sites More sharing options...

Bannko Posted February 20, 2017 Share Posted February 20, 2017 It is better to go to your local ford dealer and ask them if they can provide a picture where is the light module located. You will definitely need the facelift modules. If you won't be successful i will buy those lights from you :D Quote Link to comment Share on other sites More sharing options...
ronseal Posted February 20, 2017 Author Share Posted February 20, 2017 Bit Stuck on this light module inside the light idea.. happened to have an old 2013 and 2015 smashed light outside in the skip (as i'm doing a clear out) from previous projects so thought i would do a little investigating. after striping the looms out of each unit they seem to be pretty much the same the only thing they plug into (other than Bulbs) is the headlight aim adjuster motor and i cant see that that would be coded to the vehicle (may be wrong) the only difference between the two looms is the MK3.5 has another connector so looking from top to bottom left to right we have MK3 = 1: aim adjuster / pin 2: aim adjuster / pin 3: low beam / pin 4: low beam to indicator & Main beam to sidelight / pin 5: aim adjuster / pin 6: indicator / pin 7: main beam / pin 8: sidelight MK3.5 = pin 1: aim adjuster / pin 2: aim adjuster / pin 3: low beam / pin 4: low beam & indicator / pin 5: sidelight & Main beam / pin 6: aim adjuster / pin 7: indicator / pin 7: indicator / pin 8: main beam / pin 9: sidelight I may be wrong but the only difference i can see is that they changed the plug configuration to add an additional pin, so instead of pin 4 doing two jobs on the MK3 light (linking from Bulb to Bulb) it has its own pin so if i take the plug out from the car end and add pin 5 to the loom this would in essence reconfigure as per the MK3.5 i may see if i can get hold of a plug with some wire from the car end of a MK3.5 and make a mini loom connector (to go between the two plugs) in case it doesn't work if anyone knows where i can get a cheap one from 2015/2016 focus.. I am just thinking out load here, any suggestions welcome 1 Quote Link to comment Share on other sites More sharing options...

ronseal Posted February 27, 2017 Author Share Posted February 27, 2017 Just a quick update, purchased a set of 2015 plugs of eBay which arrived this morning - made 2 mini loom connectors and 40 mins later all wired up and working 100% with no error messages and everything working as it should..no modules or coding required.. if anyone else wants to give it a go i've done a quick guide in the how to section 1 Quote Link to comment Share on other sites More sharing options...
DJ_Andy_M Posted February 27, 2017 Share Posted February 27, 2017 That's awesome news! Perhaps the halogen lights aren't as technical as the Xenon ones! I had a look in mine when I changed the bulbs, there's circuit boards and god know what else going on for things like adaptive lighting!

ronseal Posted February 28, 2017 Author Share Posted February 28, 2017 I know, i was a bit surprised myself as wasn't sure if it would work....sometimes pays to just give it a go... I deliberately avoided the xenon headlights as i think i would have come up with issues using them. Quote Link to comment Share on other sites More sharing options...
kpg Posted February 28, 2017 Share Posted February 28, 2017 A full list of parts needed would be awesome dude. Like did you need to change the front wings too ? Quote Link to comment Share on other sites More sharing options...
ronseal Posted March 4, 2017 Author Share Posted March 4, 2017 Hi KPG it all pretty easy to be honest, wings are the same front panel is slightly different but there's no need to change it just a little jiggling around to get it on tight, you need the following: Bonnet bumper headlights - (plus the loom fix as mentioned above) lower splash guard cover - (you can modify the one you have but if you want it to last i would recommend a genuine ST one as the bumpers differ to the standard 2015 splash guard) depends how authentic you want it... you should really change the two front air ducts (again you can use your current ones - just need a little cutting to fit but on close inspection you'll be able to see them behind the grill - not sure on ST to ST as they may be the same) i also replaced rear bumper rear lights ST interior ST headlining and pillar trims 2015 head unit and screen 2015 centre console and arm rest and hand brake (this was a bit of a mission as it required modding to get the AC panel in the hole the 2015 panel goes in as its a different shape - i just made a solid plate out of black perspex and cut to size for the old panel to fit then fitted into the hole for the 2015 unit as luckily its bigger) 2015 steering wheel & Airbag - you can use the 2013 ST stuff which saves on changing all the arm rest / head unit / handbrake / airbag etc exhaust ST illuminated door seals 1 Quote Link to comment Share on other sites More sharing options...
