I have a 91 wrangler which the front vaccum motor is junk in it to engage the front axle. My buddy gave me one from an 87-90 year style on. For those of you that dont know. The 87-90 have 3 vaccum ports and the 91-95 style has only 2 ports. My question is what is that third vaccum port for? I know one is vaccum one way to activate it, the other is vaccum to pull it back, but not sure of the other.  |

from what i hear it can be used without that port,,,I guess its just for the part time light on the newer ones.
When i had my vacuum shifter hooked up manually with valves, i didnt use that port.

two of them are for the motor anf the third is for a vacuum swich on the firewall to turn on the 4WD lamp. you can just cap it off at the diff or run another line up and cap it somewhere else.

I have it capped off at the diff and I added the 4x4 light switch for the newer style one on to this. Thanks for the info guys.
