Hello,
Hope everyone is enjoying the weekend! I'm working on the installation of some new headlights for the M3W. I'd like to install these headlights because they have an integrated turn signal and I like the look.
Reaching out for some assistance as I have come into some challenges. Any assistance and sassy comments of how this may be beyond my at home skill level are certainly appreciated! smile

JW Speaker EVO J3 Headlamps Procedure
NOTE: This headlight has integrated turn signals and H13 connectors for both the headlights and turn signals
Removal
1.) Remove upper OEM headlight trim hardware.
2.) Tip forward and remove OEM headlights from buckets.
3.) Disconnect H4 connector from OEM headlight.
4.) Set aside and store the OEM headlights.
5.) Snipped the H4 connector wires and removed OEM H4 connector.
6.) Snipped red and white wires of the left and right OEM turn signals.
7.) Set aside and store the OEM turn signals.

Installation (so far):
1.) Purchased (4) aftermarket H13 connectors with pigtail wires.
2.) Installed and test fit the JW Speaker EVO J3 headlamps to the existing trim ring and buckets.
3.) Reattached existing headlight and turn signal harness ends to the headlight and turn signal connectors on the M3W side.
Conducting a test fit of wires before final splicing, heatshrink, and loom

Table for Existing M3W harness colors
EXISTING HEADLIGHT HARNESS
• BLUE WIRE WITH RED STRIPE = LOW BEAM
• BLUE WIRE WITH WHITE STRIPE = HIGH BEAM
• BLACK WIRE = GROUND
• RED WIRE WITH HEADLIGHT WIRES = POSITION?
EXISTING TURN SIGNAL WIRES
• RED WIRE = Turn signal
• WHITE WIRE =

Existing wires pairing with JW SPEAKER EVO 3 HEADLIGHT
EXISTING HEADLIGHT HARNESS
• BLUE WIRE WITH RED STRIPE splices via aftermarket H13 to YELLOW WIRE for low beam
• BLUE WIRE WITH WHITE STRIPE splices via aftermarket H13 to WHITE WIRE for high beam
• BLACK WIRE splices via aftermarket H13 to BLACK WIRE for ground
• RED WIRE AT PLUG WITH HEADLIGHT WIRES = not used at the moment
EXISTING TURN SIGNAL WIRES
• RED WIRE splices via aftermarket H13 to ORANGE WIRE for front turn
• WHITE WIRE = currently not used at the moment

What’s happening:
• Low beams work when the headlight switch in the passenger area is turned ON
• High beams work when the headlight switch in the passenger area is turned ON and stalk is pushed forward
• Rear turn signals will work if the headlight turn signal is OFF, but is very dim and not bright as normal
• Front turn signals will only work if the headlight switch in the passenger area is turned ON
• Rear turn signals will be bright again if the headlight switch in the passenger area is turned ON

Do the JW Speaker lights require power on the DRL input to function normally? Some of the aftermarket LED headlights that switch between DRL and turn signals need this, so it’s worth a try.

You may have ground problem, or really a lack of ground problem. The other turn signal wire (WHITE) is ground. Recall that the turn lights are all plastic... Not sure where the ground is for the new lights, but I'd verify that all the ground wires are connected properly. A back-feed ground can cause all sorts of strange behavior.

Please note that existing turn signal wires should be green/white and black for right hand indicator and green/red and black for left hand. The black ground connections should not be needed as ground is already supplied via black wire from headlamp loom.

The existing red/orange wire in headlamp loom provides power for side/position lights, but you seem to have connected these to indicators (orange wire) on the JW headlights confused2
This would explain your results.

I would guess if you connect existing red/orange wire to red on each JW headlight this would give you position light function. Then just wire each indicator cable to same side orange cable on JW headlamps this would give correct flasing indication.

Installation instructions here although you probably have them already. Note it appears there is a sixth connection (blue wire) for DRL function.

Hello,

Yes that is correct for the turn signal wiring on the M3W side before the original factory harness. Here is an example photo of the passenger side (in the USA) of this car. Also a picture of the original harness before I cut off the H4 connector.

The red and white of the factory harness went to the OEM turn signal
The other 4 wires went to the OEM headlight (but not that red wire in those 4, which was just sitting in the headlight bucket with electrical tape over it)

Looks like the position light is not used in the US version.

The green/white wire shown in your post above is as mentioned already, r/h (passenger side on US car) indicator. This needs to ultimately connect to orange wire on r/h JW headlamp and green/red to orange on l/h headlamp.

It seems the red and white pair of wires from the OE indicators themselves although not shown in the chassis loom diagram, connect to the standard colour coded wires as mentioned above. Check which is the live side though (red or white?) as this is the relevant one, ground side can be ignored in this case.

Hello Richard,

Yes the set of two wires (the red and white) came with the car and was OEM hooked up to the wires you mentioned above (Green and White and Green and Black) and went to the OEM turn signals at the left and right sides of the car. I've owned this particular car since new.
Below is how it is wired up for the new headlights:
• OEM BLUE WIRE WITH RED STRIPE (LOW BEAM) -->YELLOW WIRE OF NEW HEADLIGHT(LOW BEAM)
• OEM BLUE WIRE WITH WHITE STRIPE(HIGH BEAM) -->WHITE WIRE OF NEW HEADLIGHT(HIGH BEAM)
• OEM BLACK WIRE(HEADLIGHT GROUND) -->BLACK WIRE OF NEW HEADLIGHT(HEADLIGHT GROUND)
• OEM RED WIRE (POSITION WIRE?) --> not yet hooked up

• TURN SIGNAL OEM RED WIRE -->ORANGE WIRE OF NEW HEADLIGHT (HEADLIGHT FRONT TURN)
• TURN SIGNAL OEM WHITE WIRE -->not yet hooked up

Hmmm it might be because the headlight as a whole is not energized unless the headlight switch is turned ON.
May need to route an additional power line (unused seat heater relay?) to the headlight and this will provide power via ignition switch being ON?

Or will try to route the white wire of the OEM red and white turn signal wire set, to chassis ground location.



Think this may need to be buttoned up by an electrical expert. Was hoping this would be more plug and play with just matching the wires up but alas...

Thanks for the replies so far though! Have a good evening

Had a look through the instructions and nothing to suggest you should need headlights on (or DRL's) for turn signals to function. However the standard turn signal setup is controlled by a "TSM and headlamp" module which has been known to cause vagueries (used to very occasionally get uncommanded hazard function, cured by turning hazard switch on then off). Given this, might be worth hooking up the ground side of turn signals (white wire) to ground (black) on JWS headlamps. Note the instruction sheet shows two plug and play connectors for headlamp and turn signal with the latter connecting to both OE turning signal cables.

Other US M3W owners have fitted JWS headlamps but maybe EVO 2's although I remember one TM member fitting a version with integrated turn signals. In any case suggest you contact JWS. Are you keeping OE turn signal lamps and adding the JWS ones in parallel BTW? It shouldn't make any difference given low current draw but who knows.

Other observations: There is mention of a lens heater (30 watt) on the back of lamp.

Assuming your headlamp switch has a redundant sidelight position (I know latest versions are simple on/off), you could add position lights by extending the red/orange and red/black wires each side that have been cut off inside your headlamp buckets, or you could hook them up to DRL connection depending on what is legal in your state.

Hello Richard,
Thank you again for taking a look at the documentation. Where I am experiencing the troubles is:
1.) There is a 6 position deutsch connector in the headlight for the wiring to go through. This deutsch connector does have the two mentioned and included H13 connections attached.
The 6 position deutsch connector in the headlight is as follows:
(1)YELLOW WIRE for low beam
(1)WHITE WIRE for high beam
(1)BLACK WIRE for ground
(1)ORANGE WIRE for front turn
(1)RED WIRE for position
(1)BLANK spot

This deutsch connector then leads to the headlight H13 (for a jeep of course, hehe) and an H13 connector to hook up to the jeep turn signals.

Where the problem and trading of wires occurs in application on a M3W is that the H13 turn signal connector from the deutsch is wanting to pair with:
(1)ORANGE WIRE for front turn
(1)RED WIRE for position

As we know, the M3W OEM turn signal is (1) turn signal wire and (1) white ground wire

This leaves me with having to find a place for that M3W OEM turn signal white ground wire to go. I've touched it to the black wire on the headlights and of no success yet.
I've also stripped the wire end of the M3W OEM position to see if I could pair that with the headlight RED WIRE for position. No good there either unfortunately.

Perhaps, this vehicle is just destined to have separate turn signals and my dream of all in one unit is not going to happen without some further modifications.
