rotary switch

I have been trying to figure out how to wire a rotary switch in my car and "call me thick" I am having a tough time figuring this out. I wondered if anyone has any tip or help could help me out. What I need to perform... I have 4 connections/positions: 1) An empty position lack of connections on other positions (that should be easy just don't add wires to that selection setting). 2) A normally open positive to positive connection that should be closed when position 2 is selected. 3) A normally open negative to negative connection that should be closed when position 3 is selected. 4) A normally closed positive to positive connection that should be closed when position 4 is selected. NOTE: If 4 is too complicated that is an option, I consider would be nice to have but not absolutely necessary. After researching this stuff I was thinking perhaps a "3 pole 4 way" rotary switch would fit my needs but can't figure out the details on that. At this point I was considering perhaps just getting a "3 pole 4 way rotary switch" and just playing with it to see if I could make it do what I wanted. So if anyone has any advice for me on what I need, how to wire it, where to get the supplies I need, just about any information you would consider helpful, I would be very grateful.

Does 2 need to be retained when you switch to 3?  Does 2 and 3 need to be retained when in position 4?

Thanks for the response. The answer to your questions is no, no other switch needs to be retained when another switch is selected. In fact what I am working on is pretty flexible for that situation. position 1 requires no other switch to be turned on (the only picky switch). position 2 when on will automatically override 1 and yield to 3 position 3 will override 1 and 2 position 4 is completely unrelated to all the others.

A 2-pole 4-position switch unless 4 is a different supply to 2 in which case 3-pole 4-position (as it seems to be).
