My first contribution to DIY section
My car is RHD, but i believe the wiring would be the same, as i followed "engine start button" and "steering wheel audio control button" wiring diagrams from this DIY section (LHD)
Open the steering collum
1. pull the steering onward and lowered the steering wheel (RED arrow)
2. push at each side of steering collum and push upward (green arrow) to remove the collum
3. remove 3 screws from bottom collum (at the bottom of steering wheel)
4. just pull down the bottom collum, don't have to remove.
unplug the green connector (color may vary), by push the lock button located at inside (facing inward)
5. peel the sticky tape (do not cut) and exposed the wires by remove the tube protector (do not cut)
WIRING
6. now, the interior wires :
the first wire is + and second (orange) is (-)
7. please see carefully, the odd shape of the connector is facing to front (RED ARROW) and flat shape of the connector is facing backward
and tap the wires from keyhole light to these 2 wires.
1 = interior (+)
2 = orange color = interior (-)
MAKE SURE BEFORE YOU TAP, YOU PRESS UNLOCK BUTTON FIRST TO LIGHT UP THE INTERIOR LIGHT.
and start tap, if the keyhole doesn't light up, swap the wires from keyhole light and tap again.
8. sealed, PROPER SEALED !!! the wires.
9. install/plug the keyhole ring light. Advise: close the door and lock, to make interior light dimmed off (so the keyhole light), otherwise too bright..might blind you eyes...LOL
10. Enjoy !!! I guarantee, you'll LOVE IT !!!!
