Well, the '64 is finally running! The engine actually starts and idles!
( I haven't driven it yet .....)

Yes, there are more things to do, but I'll take the small victories where I can.
( Thank you all for all the advice and guidance! It made the difference! )

Now there are three unconnected wires looking for a home. The three are located right beneath the anti--freeze/Coolant reservoir ( removed as you'll see in the pics )

One wire is solid black, another is solid dark green, and the third is a light green with a black stripe.

Where do these wires connect?
( Or do these wires connect anywhere at all? Are they all terminating here and do not connect anywhere? )

Also as I looked further below the now vacant reservoir area, there was yet another wire! This one was a light yellow with a black stripe ( perhaps it was originally white with a stripe but yellowed with age/time )

Any ideas on where these wires go -- if anywhere?
And what they connect to and what they power?

Thanks and regards!

 

1964,
If I can suggest any major supplier has a wiring diagram book, its about 20 pages, all your headaches will be gone, Its like 15 dollars.
Green/black and green solid seem on my mark 2 to do brake light switch and starter carb solenoid.
A lot easier getting the schematic.
Good luck

Try this:-

the first photo wires look like the three wires for the Screenjet 2SJ wiper-washer system in these cars. See picture.

Jose! That's it! But my car does have that pump. But there is a vacant place for it that matches. Thanks for solving the mystery!

 

you welcome! Those pumps, (the 2SJ Screenjet pump with the three wires), don't last long, they burned out 3 months after new.

Just get a modern windshield washer pump and use two of the wires, the third wire can be taped away, not needed. If you have the original glass water container, you can use it with a modern pump, for example, remove the pump from any other Jaguar, mount it nearby but lower than the glass container and draw water from it.

 

Excellent advice! Thank you!
