look at the diff. It should have one breather hose and possibly two little wires if the truck has ABS. If the truck has a locker, there should be some other air/vacuum line stickin' out of there somewhere.

There's a hose running from the left rear of the diff to the hollow tube that runs under the bed between wheel wells. I'm guessing this would be the breather? There's also a hose coming off the front, right behind the driveshaft, that runs along the frame toward the firewall. This would be for the locker?

The plate on the firewall has 422 after the engine codes- looks like the diff gearing. What different ratios are available and what are they best for?
