[USMC] Harrier Flight (2013) VIDEO Utube
I remember the F-4 yaw string was fitted further forward then the bottom of the screen. In the early days there was a reference line marked underneath it too, which was odd as you had to be a wingman to see it. I don't even remember it being a requirement before flight so perhaps it drifted out of use.
The F-14 yaw string was a no-go item if it was below a set length:

Well, having hunted around the Web, I've found photos of a 56(F) Sqn F-4 fitted with a yaw string, but not as shown in the previous photo. It seems to have been fitted at the base of the windscreen support, as Rp stated.
But I don't recall ever having seen one, let alone used it. How it was supposed to remain attached at supersonic speeds and cope with English rain, I cannot imagine.
I remember the 'danglometer', a little yaw string with a dayglo cone on the end on some glider though!

Here are a couple of low-res scans of the pics I took at Wattisham, you can see the 'yaw string' and its attachment point just below the base of the windscreen...

The F-4 yaw strings frayed, obviously, and generally fell off after time. We only used to renew them when we went off to APC to get the best out of the gun - especially as the gunsight was't really optimized for a 180 kt target. We'd use it to trim the yaw at the appropriate angle of bank proir to shooting and, thereafter ignored it.
