4WD Technical Question

[Skidmarcx]

Got a question regarding my 4WD conversion. I got the parts off of a 97 Limited like mine, so it has the push button 4WD... Thought it would be cool to have it look factory, but have full control. I've wired the tcase motor to a double throw momentary switch and the vacuum control for the ADD to a pneumatic push/pull switch. Everything works, but since I don't have my hubs yet I can't drive my rig. My question is there a specific way I should engage 4WD? Diff first or tcase first? Not sure if it matters... Thanks in advance

The factory systems are set up so that the front diff engages AFTER the tcase has engaged. So I'd do it that way.

Thanks that's exactly what I needed to know!
