1996 Jeep Cherokee Sport XJ Fan Override

Hello everyone! I was just wondering which wire from my 1996 Cherokee would be the high-speed setting for the fan. I want to install an override switch to have better control over my cooling system but I cannot find anything online for a 1996. I see 91-95 and 97-01 but none inbetween. I know that I just need to drop a toggle switch inbetween the wire and I'm all done but I have no clue which color wire is the high-speed for the electric fan so when i turn the switch on the fan will turn on as well. Please help.
