Mark, You have a 2+2 with air, its simple, power,master 1 wire, gm mini 1 wire all fit which there have been many posts already. Just tape all 300 wires from your old alt back and run a 8 gage wire from the back of the new unit straight to the positive post. YOU WILL NEVER REGRET IT, Now get halogen bulbs and you can see at nite too.....
