Installed on a 1991 wrangler-trying to chase down the application for a firend and I do not have the truck here-just this pic to go by...

I never saw a front vacuum actuator have an electrical connection ona YJ Dana 30 before-I am assuming is not factory OEM. 5 bolt-not 4

Can anyone tell what it may be from? Or am I missing something....sorry about the big pic-my image editor is not working

The HP30 in my YJ (out of a 91) has that connector, the factory 1988 HP30 does not. I assume it is for the 4x4 light.

I agree, looks like my dana 30, wire is for the 4x4 light on the dash.
