Jaguar Mk 2 3.8 Automatic wiring nightmare

Hello, hope someone can help, I am trying to figure out the wiring on My 1964 Jaguar Mk 2 3.8 Automatic, someone has messed with wires everywhere, I have various wiring diagrams and still struggling, I am currently working on the centre dash gauge area, I have figured out most of the wires but have some left over and don’t seem to have enough for other things, does anyone have any good close up pictures of the centre gauge panel area so I can possibly see and work out my wiring, regards Paul.

Hi Paul. Several of us put this thread together in '17. Hope it helps. Please let us know where you are - maybe someone is close by. Paul


Hi Paul, here are a couple of photos, 3.8L automatic. It includes a couple of incorrect wires and splices, but perhaps it helps.

Hello Paul,

our '63 LHD MK2 is equipped with a 3.8L engine and Borg Warner DG250 automatic transmission. The central Lucas light switch is a 4-position unit as our car is equipped with Lucas fog lamps. I installed an Autosparks harness when I restored the car. Hope this provides some assistance.

Hello Paul, thanks for the reply and info, I have printed off all the info and pictures and will study and see if this sheds any light (no pun intended!) I live in Yorkshire
