The wiring diagrams

 This is the wiring diagram for the left light.

This is the wiring diagram for the left light.

The differences in the wiring compared to the halogen headlights are:

Pins 9 & 10 – Need new earths
Pins 7 & 8 – Need swapping over.

Pin 12 on XE2 needs removing and rewiring into AFL control unit.

Modifications to Headlight loom connector

If you want to manually add the missing earths it can be done with this method

  1. Remove the bumper & existing headlights.
  2. Drill through the empty 2 positions in the headlamp loom connector
  3. Fit appropriate female terminals into the empty holes.
  4. Connect these 2 new pins to the 1.5mm brown earth cable already in the loom or to one of the chassis earths.
  5. Use a terminal extractor and swap over pins 7 & 8 in the loom connector.
  6. Insulate & cloth tape up the loom.
  7. Carefully fit the AFL headlights which have been fitted with bulbs, power & control units.

If you want a simple plug and play solution, we manufacture and sell a jumper loom to add the earths and swap over the pins 7 & 8. We also sell a complete loom with all the wiring necessary.




Headlight Loom

Full Retrofit Loom

The Levelling sensor.

 p/n 93186708 - Make a new loom up with sufficient cable to reach the passenger footwell. Do not use the terminals provided as they will be used in the fuse box.

 There are 2 studs on the car body near the fuel tank, this is where the levelling sensor fits.

The studs will be corroded as they have been exposed. Carefully remove as much of the rust as you can with a wire brush or Dremel. There is a risk they will be sheared off if not completely cleaned.

Additional wires to add to the UEC

 Remove the battery and the lid to the fusebox

Remove the battery and the lid to the fusebox

  1. Remove existing level bit signal (pin12) of XE2 which goes to the levelling switch.
  2. Insert the following termonals and run the cable through the grommet to behind the glovebox
  • AFL Ign Voltage
  • AFL HS CAN Low
  • AFL HS CAN High
  • Level bit signal

The AFL Control Module

 Remove the glovebox, run the wires from the fusebox through the firewall to the rear of the glovebox.

Remove the glovebox, run the wires from the fusebox through the firewall to the rear of the glovebox.

  1. Connect an earth to the earth stud below the glovebox.
  2. Fit appropriate terminals to the ends of all the wires.
  3. Plug them onto the correct pins of the control unit.
  4. Connect Tech2, program the AFL control unit and enable AFL on Highspeed CANBUS and all the modules which have AFL within the variant configuration.
