Taping up the loom in the wiper mechanism area I found a brown/black wire folded up and taped into the loom.

Can anyone tell me what this is for?

I have the wiper motor correctly wired up as per the drawing I found and there are no spaces left to connect to.

The fresh air motor connector is fully wired as is the fuel sender. The brake like switch is a single wire and is down in position.

I cannot fit this wire anywhere in this area.

If I'm not mistaken... It's for the intermittent wiper relay

Like this? Believe it goes to pin 5 on the wiper stalk.

That is exactly what it is. The factory wire for the wiper delay relay, 1972-76 cars only.

Thanks for help.

My car is a 74, why would it be taped off? Is the intermittent phase an optional extra?

Yes, I believe it was a dealer option.
