It's the ground wire for the horn. There is a screw on the PS rack for the loose end. (I don't remember exactly where it is on the rack.)

Is it necessary? I say this because my horn works.

Chassis ground..? I have one bolted to the crossmember.

It is a ground strap from the steering rack to the x-member.

Does it do anything if i connect it?

The steering system is made up of various metals (aluminum, steel, cast iron) and over time very slight electrical currents can (maybe) cause corrosion. Grounding everything helps to prevent this. The effect is what causes much of the corrosion in cooling systems. Your steering rack might spontaneously fall off your car in about 200 years if you leave it disconnected.

I left that wire off once and my car rotted in 2 weeks time. I also got oil in my coolant, snapped my belts and my power steering started leaking. Ground it...

Colin - I love your collection of Z cars! I had a '79ZX in blue. I wish I still had it. With a turbo and minus the rust of course!
