I'm trying to locate the black/brown wire marked "T1a" on the '74 wiring diagram, that is supposed be "near fuel tank", and which I think can be used to power an electric windscreen washer pump (it comes from the stalk switch on the steering column).

My problem is that I can't see where this wire is on my car. There is some overspray on the wire bundle that emerges into the front trunk from under the dash, which makes seeing what is there difficult.

Any help/advice would be appreciated!

It's brown with a black stripe. Originates at your steering column and is in the main bundle going into the front trunk and terminates right around the drivers side fresh air divider box thing.
It may be hidden inside the loom. It was on my car.

OK I have found the wire: it emerged at the place you indicated, and was folded back and taped, hidden, to the wiring bundle.

After extracting it, I checked for +12V when pulling the column stalk towards me: nothing. My car is a '74, but it doesn't have the intermittent wipe option - is that relevant?

I'm a little confused now, as my owner's manual says that the windscreen washers are activated by pulling on this lever, as I am doing. Yet the system in the '74 used the spare tire pressure to eject the water, so how is the column stalk supposed to turn that on and off, and what has it got to do with the brown/black wire?

Sorry, I'm new to 914 wiring (IMG:style_emoticons/default/blink.gif)
