Back to working on the XJ6, 1977 with 1993 LT1.
I am replacing the small headlights with larger set I purchased from Australia. The set is complete with bulbs and wiring. There is an extra wire on the Australia set, what is it for?
Mine has 3 wires, blue with red stripe for light, blue with white stripe for high beam and black for ground.
The Australian set has the same wires plus a red one…
My Haynes manual does not show this red wire.
Know what its for?
