Hey guys. So I'm posting about the wiring for the headlights. I know projectoreetrofits has the wiring but I can't get in contact with them at all and I'm trying to do this soon. Would a regular HID conversion kit do the same? Could someone point me in the right direction? I would really appreciate it

LEXiiON

I built my own harness for my 2010. I assume you have halogen headlights?
I can post some ideas...

If you could that would be awesome! I'm a terrible electrician. It's nothing I really want to tap into, but I would love to hear if you have any ideas that I might be able to use!

LEXiiON

Ok.. here is something to start with.
First you need the 2013 Headlight connectors 2x: CU2Z-14S411-ADA
Then you need 2x the turn signal connector: 3U2Z-14S411-FHAA
Additionally you need 2x relays and a fuse-box that holds 4x fuses, some wires and 2x 470uF Capacitors.

In order to get this working you need to wire it up as mentioned below:

You need 2x 20A fuses supplying power at all times to Pin 10 of the HID connector (see diagram)

The "old" low beam signal of your halogen goes to Pin 1 on the HID connector. In order to avoid flickering, add the 470uF capacitor between pin 1 and ground.

Pin 12 will be the old high beam signal. However, with halogens, the low beam shuts off. So you need to add the relay to power the low beam while the high beam shutter solenoid is activated. See below diagram #2 where the relays are in.

Pin 5 of the LED strips has it lightened up full power, pin 3 reduces the power. You can wire them up per diagram for turn signal and parking lamps.

Diagram 1 (2013 HIDs), Diagram 2 (Low-beam relays diagram - that is for a 2011 but the schematics is the same), Diagram 3 is the turn signal connector diagram.

I appreciate the info! Really helpful. I still get a little worried about doing that much work with my electronics (not a lot of experience in that field). I wonder if a regular HID conversion kit would work with the headlight assemblies? I'd really be willing to do any sort of mod as long as it came as a kit and wasn't too much of a process

Lexxion,


The turn signal connectors that you mention above are they for the 2011 or 2013 mustang? I looked them up and they are the 2011 which the car already has so there is no need to buy them unless they are the male type that will connect to the existing female connector on the car. Did you mean buy 2013 turn signal connectors?

LEXiiON

These are the 2010-12 connectors. I removed the pins and slid them onto the headlights without the connector and taped them, as at that time there were no connectors available.

Here is the 2013-14 connector

these connectors you built, they handle all the power? from high beams to the signal/light bars on the 2013 headlights? if so do the signals light up white and blink orange?

LEXiiON

No. I bought the connectors for the 13 HIDs itself, but the turn signal is a different one and was not available. High beams on HIDs is just a actuator, so no high power. I used the relays to power the low beams while the high beam actuator is active.

The signals are just turn signals. They only blink orange. The white LED strips are running if wired correctly from switched source.

I am trying to build a harness that just plugs into the Morimoto harness. I have tried to test the pins and think I figured it out. can someone verify it. Sorry for the bad pic. one thing I notice that two of the pins both turn on drl. I connected the low beam and ballast together. before I finalize wanted to get input.

LEXiiON

Pin 3 for the LED strip is switched 12V (full bright power)
Pin 5 for the LED strip is Park lamps (it will dim the LED's)

LEXiiON

Vartech

So how would I wire into a 2010 non hid car? do I just pick one? If I want full bright use pin 3 and if I want dim leds use pin 5? I have been playing with harness and notice that the high beam ground is shared with the ground of the DRLs. I want to know if I should connect the low beam and ballast together I think pins 1+10(power) 8-ground.

LEXiiON

I did put 5 on a switched source and 3 on the parking light. The parking light is not used in the 2013+ HIDs so you can just move that pin to the big connector.

LEXiiON

Vartech

I want to add a switchback like the 2013 to have them turn off when the turn signal is on. If I wire both pins won't it not work?

LEXiiON

Ok. So if you like that operation, keep in mind, that the switchback only works when the lights are off on the 2013. Once the headlights are on, there is no switchback function.

The whole headlight function is done in the SJB. If you want original 2013+ function, either grab a 2013 Mustang SJB and swap it or program yours to 2013 and wire it up according to the diagrams. The SJB's are the same from 2011-2014 and just programming them enables HIDs and the LED strip. No need for a external HID driver, etc.

Vartech

Ok I think I have it. Let me know if this makes sense. I already have a morimoto xchange driver. If I connect pin 3 full led to the wire for turn signal when the headlights come on I get full led, If I connect pin 5 low led to switch back that will only work when the hids are off. would the leds suffer damage when both pins are suppying power. My thought is since pin 3 is only hot when the hids are on then pin 5 would be the only power supply when they are off and connecting to xchange would be fine. My only concern is when the lights are on both pin 3 and pin 5 would be hot when turn signals are not in use. I am not that skilled to do the SJB swap. looking to make this plug and play.

LEXiiON

Pin 5 power and Pin 3 power will work at the same time. The LED strip is dimmed when there is power on Pin 3. I Would connect the parking light to PIN 5 as that would go off when the turn signal is on. So that gives you the switchback. Then wire pin 3 up to power from the headlights, which will dim the LED strip once the headlight is on, with no switchback.

LEXiiON

Vartech

Thanks for your help. I will keep you posted once I am done.

Vartech

ok running into issues. Opted tokeep led full removed pin 5. Problem I am having is switch back is not working when I connect high beam. Is it because they share same ground?? How do I speprate the grounds? Where do I connect them?

LEXiiON

Hard to say if it has to do with ground. Ground is basically common everywhere in the car... Something else might be wrong. Connect the ground to the chassis somewhere
