Ticking Noise Update...ABS Related?

An update on the ticking noise which seems to pulse at about half the crank speed, and only audible in first or second gear, sometimes while in neutral - at rpm's between 1400 and 2000. 

Car is an '87 NA.

The sound goes away when the brake pedal is applied - and I'm thinking that there might be some sort of erroneous ABS signal causing this.

Does this ring any bells for anyone?

Are you able to locate where in the engine bay the noise is coming from?  I had a ticking from in front of the glovebox in the engine bay, turned out to be the cruise control going bad.

Noise is coming from below, and just a bit to the passenger side, of the gearshift.

you just rang a bell for me...

I remember now, I had a similar noise. Turned out to the cruise control servo. It has failed (long time ago) and was now stripping the gears inside. Brake application would make it shut up.

Hope this helps...
