Does anyone have a schematic of the fuel pump relay?

I would like to install a kill-switch by connecting the relay to the AC and have the AC **** as my switch. This would require a second set of relay contacts to lock in the fuel pump (so I can still adjust my AC while driving).

Also, does anyone have any advice on making a kill-switch (something simpler, other ways of going about it, etc.)?

Thanks.

Edit, forgot to mention car: 97 Avenger ES

 

Put a relay on the fuel pump + wire itself under the back seat ...wire it to a hidden switch or a magbetic reed switch
