what are these wires coming off this third member

The guy told me it had a spool, so there is no posi to lock up?

I emailed him asking what is up and got no response. Its a Mark Williams unit.
So, what are the wires coming out by the yoke?

 

Just a guess here..... wires to hook up the rear ABS speed sensor on a newer model application?

 

your probably right

I think your right.

Here is his response.

"40-50 passesthe wires are for a computer pick-up---the ratio is 4:86 pro"

Thanks for you help,

Now thats what I like to see, car parts inside the house. My wife won't let me do that any more. ou:

 

That's a pretty hardcore looking third member for a racing application, Ford 9" maybe.

The wires go to the pickup pointed at that ring you see on the yoke, which measures driveshaft speed.

And a spool means the rear axles are locked together solid; no differential action at all.
