mess

Hi , I'm a total new guy to forums and such. I'm sure someone has encountered this issue I have a '88 wrangler 4.2. I got it not running and a total wiring and vacuum tube mess. trying to eliminate most if possible. Are there any alterations for the vacuum controlled 4x4? Don't need auto...

90 yj had carb motor. Guy I bought from put in 95 4.0. The wiring dont match under dash for heat. How do I merry the 90 and 95 wiring together. Found wiring diagrams but don't tell what power and what wires are hi and low. Help my first jeep I bought a mess.
