This will be important for later on. If you have any problems finding out 

which controller is yours. Take a picture of the rear of the motherboard 

and send to Jackson@jmods.co.uk and ill get back to you which is version 

of controller is yours.



Opening Controller 

There are 7 screws (T8) located on the 

back of the controller. All must be unscrewed. 

Please Note one of the screw is 

located under the warranty sticker (Can 

be removed carefully with tweezers or 

go straight through with the screwdriver. 

The easiest way to pull the controller 

apart is to push both thumbsticks 

through and pull the back off carefully 

(must keep the front facing down or buttons 

will fall out).



Preparing Bowtie 

This is what you will receive in the pack 

pre-wired LED glued into place on in the 

bowtie. Check both sides to make sure no 

excess glue has been covered onto the 

hole. 

There will be four wires coming off the 

bowtie piece. (two negative, two positive). 

There is three easy way of checking 

which is which. 

1. Look at the LED (as pictured above) 

one leg of the LED will be longer 

than the other) and the longer leg is 

the positive. 

2. (not the easiest way) Get a battery 

and connect one end to each and 

check which way round works. 

3. Connect the transistor and find the 

positive pin and try either way 

round. (not for rumble activated) 

Once you found each positive wire hold 

together (by twisting or soldering) for the 

next step, also do the same with the two 

negative wires.



Preparing Controller 

To make sure the pre-wired bowtie fits 

okay. You will have to cut the circLED leg 

of either side of the rumble motor 

holder. 

Cut the top off (about 5-10mm) and repeat 

for the other side of the controller. 

This means the bowtie will fit in easier.

Rumble Activated 

Skip to page 9 if you want the 

LEDs to stay on



Connecting Pins 

On the board you will find connected 

the rumble motors. Above the wires 

are two pins. You will see that one 

connects to the red wire (positive) 

and one to the black (negative) 

Now solder the positive wire to the 

positive pin and negative wire to 

negative pin. Repeat for the other 

side. 

Your controller should now look something 

like this.

LEDs always on 

(when the controller is)



Preparing Transistor 

Not required for rumble activated mod 

COLLECTOR 

Flat face down 

BASE 

EMITTER 

This is what you will receive in the pack 

(1.8k resistor and transistor) cut the resistor 

done to about 10-15mm. Then cut 

the middle leg down by half of the transistor 

Then solder the resistor to the 

centre leg as shown in the picture. 

(NOTE TRANSISTOR FACING 

FLAT FACE DOWN)



Connecting to a MATRIX Controller 

RIGHT HAND SIDE PIN 

For a matrix controller. The transistor 

needs to be soldered in like this. The 

collector is connected to the top pin. 

The base connected to the bottom 

pin. The Emitter is connected to the 

two NEGATIVE wires. 

Note: Do not cover the bottom hole as 

this is where the screw goes. 

To connect the power solder the two 

POSITIVE wires (as marked before) to 

the right hand pin in the cluster.



Connecting to a CG1 & CG2 Controller 

For a CG1 & CG2 controller the transistor 

needs to be soldered in like this. 

The collector is connected to the two 

NEGATIVE wires. The base connected 

to the top pin. The Emitter is connected 

to the bottom pin . 

To connect the power, solder the two 


the battery + on the reverse of the 

controller.



Connecting to a WIRED Controller (No Transistor) 

RIGHT HAND SIDE PIN 

This is connecting the ground for the 

WIRED controller. NO TRANSISTOR 

NEEDED. Solder the two NEGATIVE 

wires directly to the PIN/HOLE were it 

says GND. 

To connect the power solder the two 


the right hand pin in the cluster.



Reassemble Controller 

The LEDs should now light up when 

the controller turns on (or vibrates) 

. If not check the wiring. 

Please note: If you are using a rechargeable 

battery pack and the LEDs look dim, please 

try standard/rechargeable (1.5V) batteries. 

Reassemble controller by carefully without damaging any wires (opposite of taking 

apart). This can be tricky and can take time and care. 

If for any reasons you are stuck, have any problem or queries please contact me first 

before leaving feedback. Email: jackson@jmods.co.uk

Frequently asked questions 

I am installing more than one LED Mod. What do i need to do? 

When you are wiring your LED mods up, find all of the positive wires and solder 

them together, then do the same for the negative. Then solder to the PCB Board 

as the guides show you. 

Do i need to have more than one transistor/resistor for multiply mods? 

No. You will only ever need to use one transistor/resistor on your controller no 

matter how many mods your install (not required for matrix controller) 

The LEDs look dim, what should i do? 

Make sure you are using fresh or fully charged batteries. Please make sure you 

are using either 1.5V standard batteries or 1.5V rechargeable batteries. To get 

the most out of your LEDs please don't use rechargeable battery packs as these 

don't produce enough voltage for the LEDs. 

None of the LEDs light up when I've assembled my controller? 

Please check your wiring, make sure you have got your positive and negative 

wires together. Please check that your solder points are not touching (bridging) 

with other points. Check your batteries are to the standards listed above. If they 

still aren't working properly please email pictures of you controller internals to 

jackson@jmods.co.uk to resolve the problems. 

I'm interest in Bulk or wholesale orders? 

Please contact jackson@jmods.co.uk with your requirements.
