1996 yukon 4x4

Hello everyone, so I need some help. I have a 1996 yukon, 4x4, leather interior, with the vortec 5.7 that comes with a factory fan clutch. I have had my a/c serviced and charged with 134 refrigerant. Now my problem is I am getting 40 degrees at the center vent but it takes some time to get to 40 degrees. I live in CA and have tempeatures currently in the 100+ degrees. I wanted to install an aux. condenser e-fan but have no idea how to get this done. I was wondering if anyone has done this before to a yukon. Maybe someone can provide a basic diagram so I can tackle this. I know some will say to eliminate the fan clutch and do e-fans, but I would like to retain my factory look and just add the condenser fan. I plan on using a dorman condenser fan that I read would work for my vehicle. Any help would be great...
