sportruck4.0

I was wondering what i needed to convert my truck from a fivespeed 2wd to a automatic 4wd

Do you mean the turn signal bulb sockets?

how was the 4wd convo i have a 88 MJ (4.0 5speed 2wd) and I plan On swapping in the 4wd components it already has the axle in the front but I'm worried about doing the drive shafts and t case

Hi I'm new to the forum and I just bought a 88 mj sportruck and the running lights and instrument cluster lights aren't working for some reason but the headlights are working could it be the headlight switch or something else?
