Stoney871 Posted April 15, 2012 Share Posted April 15, 2012 This is a guide to fitting a Light Switch unit with a dimmer dial to Ford Focus without one as factory fitted. The part used came from a C-Max MK5 PART NUMBER-4M5T13A024BA Undo the T25 Torx and pull off the panel to the door side of the drivers area. Unplug the ODB port from the panel so as to avoid damaging the wiring (needs 3 hands really to push 2 metal clips and pull the Port clear) I found it was easier to reach the locating clips of the light unit from the gap at the side and had to push, pull and wiggle the unit to get it out, finally pulled forward and down to unlocate the top one first then got the bottom one clear. Unplug the cable loom from the old unit. Check the units are the same size and the plugs are the same. Attach the new unit and test the lights, dimmer and levellers. Push the new unit into place (takes a bit of a push). Relocate the ODB port into the trim and refit to dash. Replace the torx and Roberts's your Mothers Brother.

giwrgos_ath Posted December 30, 2012 Share Posted December 30, 2012 I decided to follow the guide, so i bought a part a 2006 Mondeo. That part also has auto headlights. The part will not fit my car because it is a bit larger, however all the switches and the dim was working fine. I am going to get another part that will fit my car, but i was wondering if i should go again for the auto headlights. Has anyone tried to install those? I assume i'm gonna need the auto rear view mirror with the sensors. I might go for auto wipers too. Is it as easy as it sounds or am i missing something?

TDCiST Posted December 31, 2012 Share Posted December 31, 2012 Stoney, Don't suppose you know the FINIS number do you?? Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted December 31, 2012 Author Share Posted December 31, 2012 Afraid not, the part was, as stated, from a C-Max, part number 4M5T13A024BA. Manual light switch the same as i used- http://www.ebay.co.uk/itm/Ford-Focus-II-2-0-05-2004-2008-LIGHTS-ON-OFF-SWITCH-CONTROL-4M5T-13A024BA-/400376957050?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item5d3853887a If you have auto-headlights then these are available on the Bay of e- http://www.ebay.co.uk/itm/Ford-Focus-2-Head-Light-Switch-4M5T13A024DA-/110968221268?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item19d638ae54 http://www.ebay.co.uk/itm/Ford-FOCUS-05-08-HEADLIGHTS-LIGHTS-SWITCH-4M5T-13A024-DA-/251204977626?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3a7cfbc3da There's loads of Mondeo ones listed but as found before, the unit is wider than a Focus one and definitely won't fit.

Stoney871 Posted September 5, 2013 Author Share Posted September 5, 2013 I believe after digging through microcat that the Finis code is 1471868 (listed as switch assy - lighting, dimmer, rhd, with automatic headlamp control) Quote Link to comment Share on other sites More sharing options...

Postie123 Posted February 27, 2014 Share Posted February 27, 2014 Just done this mod which was very easy thanks to your how to but the switch I got lights up green which is no good to me as the rest of my dash lights red. My car is 57 plate mk2. The eBay ad said FORD FOCUS, C-MAX 2004-2009 HEADLIGHT SWITCH, PARTS Nr. 4M5T 13A024 BA. Do you know the part number for the switch that lights up red? 1 Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted February 27, 2014 Author Share Posted February 27, 2014 All switches come with green illumination as standard but there is a seller on eBay that does converted ones. I had to request a blue illuminated unit off him, maybe you could ask him for what you are after. He's not cheap but the work is good- http://www.ebay.co.uk/usr/carparts4you2011 1 Quote Link to comment Share on other sites More sharing options...
Postie123 Posted February 28, 2014 Share Posted February 28, 2014 I thought it was early mk2's that come with green illumination and red just before the mk2.5's? Mines red as standard! Funny you should mention that seller as I asked him just before you replied and he said he could do it for £14.95 so happy days. 1 Quote Link to comment Share on other sites More sharing options...
Dee_82 Posted August 1, 2014 Share Posted August 1, 2014 Managed to pick one up with an auto on it too, in anticipation for the rear view mirror upgrade! Popped it in without probs using the guide, thank you very much! and was able to safely leave the OBD socket in place which saved some hassle, ive had a wee look though MOT guides and I don't think having an inoperative light switch position will be a problem as long as both front and rear lights turn on, only down side is its Green!! thought id been so careful checking for it but oh well, if I can be bothered ill change the SMDs to red ones one day. Thanks folks! 2 Quote Link to comment Share on other sites More sharing options...
blue crush Posted June 22, 2016 Share Posted June 22, 2016 How much brighter does the gauges go compared to when the car was stock without the dimmer control? Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted June 22, 2016 Author Share Posted June 22, 2016 The lights only go up to standard brightness but wilk go down low enough to make night driving far more comfortable on dark roads. Sent from my SM-G930F Quote Link to comment Share on other sites More sharing options...
blue crush Posted June 22, 2016 Share Posted June 22, 2016 Thanks for that. Do you know what wire controls the dimmer? I am trying to get my aftermarket gauges to the same brightness as main speedo Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted June 22, 2016 Author Share Posted June 22, 2016 Here you go, a full switch pinout configuration. The way I read it is that you have a dimmer switched headlight controller already and just want to figure out which wire to tap into for the guages? If so then you need to tap onto the wire from pin 9. Quote Link to comment Share on other sites More sharing options...
blue crush Posted June 23, 2016 Share Posted June 23, 2016 Havent yet brought a dimmer control switch yet but thinking about it. I have a dim lighting wire from the gauge but was unsure where to connect to. The gauge is bright at night compared with the usual speedo lighting.

Hellboy80 Posted October 21, 2016 Share Posted October 21, 2016 I have a dimmer switch from my old Mark 1.5 ghia. Will this be compatible with my mark 2. Also on etis it says my car has auto headlamps but not With Automatic Headlamp On/Off. I believe this means the wiring is in place but was not a added option. If I but a switch with auto lights option on it will this work? Cheers Quote Link to comment Share on other sites More sharing options...
Stoney871 Posted October 21, 2016 Author Share Posted October 21, 2016 Not compatible I'm afraid. You may be lucky enough to get auto lights but no guarantee.

Hellboy80 Posted October 27, 2016 Share Posted October 27, 2016 Not sure I want to take the chance with the auto lights. Knowing my luck I will have no wiring in place and have a switch with auto on taunting me lol Quote Link to comment Share on other sites More sharing options...
sastek Posted April 23, 2019 Share Posted April 23, 2019 Doesn't anyone know if this switch will work on a 2010 mk2.5? Quote Link to comment Share on other sites More sharing options...
