I recently posted a forum about my 87 mj when I changed out my heater core and then the 4x4 wouldn't function. I went and fixed all the lines and it still wouldn't work. The actuator is working but the fork broke inside the housing.it looks to be pot metal so I don't know if it can be welded.

I appreciate the help I am warming up the garage now to get ready to lock the CAD in place. I found a diagram of the CAD system here on the forums and it turns out that all the lines that broke went to the actuator.

While replacing the heater core I noticed that the black vacuum line going into heater box was broke. I assume that this is the reason my defrost to vent selection wouldn't work. While installing everything back I broke a multi colored vacuum harness in the engine bay next to the firewall/heater inlet. Now when engaging the 4x4 the front differential won't actuate. I know it's because of the vacuum but my question is where can I find a new harness? Also is there a quick home fix method or a way to rewire the vacuum system? I have found no replacement except for this http://4x4posi-lok.com/app_jeep.html. This part is hard lined in so the vacuum wouldn't need to be fixed though I rather fix it the right way.
