caused during the installation process.

TEP 1: Turn the steering wheel to reveal the caps and screws that need removing. Use the small flat blade screwdriver.

TEP 2: Turn the wheel to the other side and remove the other cap and screw. Starting the engine will make turning the wheel

sier.

TEP 3: ADVISABLE TO NOW DISCONNECT THE BATTERY. Lower the steering wheel using the adjustment arm and lift top of the

eering assembly.

Step One Step Two Step 3

TEP 4: Looking from above, locate the two pictured silver screws with a T20 Torx Screwdriver.

TEP 5: Remove the T20 screw from under the steering wheel on the bottom piece of the cowling.Pull off the ignition cap.

Step 4 Step 4 Step 5 Step 5

TEP 6:The bottom half of the cowling should now come away from the steering assembly.

TEP 7:You will see two T20 screws at the bottom of the speedo unit, these need removing.

TEP 8:Pull the speedo unit under and over to reveal a plug on the back, this plug will need to be unplugged.

TEP 9:The plug is attached to the back right side of the speedo unit. Pull on the red clip to release the plug. The picture shows

hat it should look like open. The plug should then simply pull off.

Now the speedo can be removed from the car, ready for the LED conversion. See Guide 2, on the next page, for the

step by step process of opening up the speedo and replacing the LEDs.

TEP 1: On the back, you will see 8 T10 screws that need removing.

TEP 2: Unclip the speedo from the black surround

TEP 3: Look at the needle positions on the front, remember where they are maybe take a photo like belowStep 1 Step 2 Step 3

TEP 4: Using 2 tea spoons, carefully lever up the needles so they come off the speedo using the spoons will prevent

e needles from bending.

TEP 5: With the needles off, turn the speedo off to the back and push through the white clip this releases the ODO

CD.

Step 4 Step 5 Step 6

TEP 6: Lift up the white plastic, you will need to push through the two black clips on the back to release the LCD

reen

TAKE CARE! The ribbon cable connecting the LCD Screen to the board is VERY delicate and if pulled

too much will simply pull off easily! You dont want to do that!

SPEEDO LED REPLACEMENT

(GUIDE #2)

DISCLAIMER:Following this step-by-step guide will ensure successful

installation, however, we can accept no responsibility

for any potential damage incurred during the installation

process.

TOOLS REQUIRED: T10 Torx Screwdriver, Flat Blade Small Screwdriver, Soldering iron (preferably SMD one), solder,

tweezers

TEP 7: The 15 LEDs that need replacing are now accessible.

TEP 8: SMD LEDs have a straight edge on one corner. Always make a note of this when removing an LED. The new LED

ust be soldered into the same position. They will not illuminate if soldered the wrong way around.

TEP 9:We used a specialised SMD soldering iron, which allows you to heat both sides of the LED at the same time. It is possible

use a standard soldering iron with a smaller tip but requires a bit more effort!

TEP 10:To de-solder the LED first note the position/orientation of the LED and heat up the solder either side until the LED

comes loose. You will see the solder melting. Remove the SMD with tweezers.

lder the new LED into position, you may need to add a little bit of solder to secure the connection.

o not leave the heat of the soldering iron on the board for too long as this can cause damage to the board.

u can find loads of help on the internet if you are not confident with soldering.

TEP 11:With all the new LEDs fitted, put the speedo back together (work backwards through these instructions) and reconnect

your car to check all the LEDs illuminate.
