Tools and extra hardware needed:

• Ratchet
• Sockets: 7mm, 10mm
• 10mm open-end wrench or adjustable wrench
• Phillips head screwdriver
• Electrical tape
• Zip ties
• Wire strippers
• Dremel tool or hacksaw

1. Jack up the front end of the car up to give yourself more room (ramps come in handy here)
   
2. Disconnect your negative battery terminal using a 8mm socket and ratchet.
   
3. Using a 10mm socket, remove the two nuts from the back of each of the fog lights. Set the nuts aside, we will reuse them on the install of the BlazerTech's.
   
4. Remove each foglight, and unclip the wiring harness. Here's the stock foglight assembly:
   



5. Remove the pins and wingnut to detach the bracket.
   
   
   
6. Using a Dremel Tool with a heavy-duty cut-off wheel, cut the plastic bracket at the "U" shaped part to give the Blazer bracket more room.  You can use a normal hacksaw if you don't have a Dremel tool, it will just take a little bit longer.  You will also have to trim off a small section of the "flat" piece where the Blazer bracket will sit (so it's flush).

                  

7. Now you need to secure the Blazertech bracket to the top of the modified OEM bracket using the supplied tape.   Then drill through the plastic OEM piece and secure using the supplied nut and bolt.

          

    

8. With that done, it's time to move onto the wiring. The BlazerTech's. come with all the wiring you need. Here is a diagram below that is easier to see the function of each wire:
   
   
9. Mount the relay in the drivers side fender area.  I mounted mine on the passenger side (because I have the fan relays there as well).  Mounting on the passenger side will require additional power wire to reach the fuse box.

          

   Use a self-tapping screw and drill a hole first, and then bolt down the relay with the two other ring terminals (Yellow & Black) underneath it.

10. Route the power wire(with the inline 15A fuse) to the fuse junction box and connect the ring terminal to the top bolt on the junction box. You will need to use a 7mm socket to remove the nut. You will also need to widen the ring terminal hole slightly to fit over the bolt. Here is the power wire hooked up:

    

11.  Route the white wire and wire-loomed wire down through the engine bay to the front bumper.
    
12. The white wire is the "turn-on" wire that activates the relay. Since we are going to keep the stock fog light switch, we need a switched 12v wire. The stock power wire from the stock foglights is perfect.  Use the supplied inline crimp connector to make your connection.  You will connect this to the purple wire as shown below:

    

13. Connect the wire-loomed wires to the foglights. The wire-loomed wires Y-split, the shorter end obviously will go to the drivers-side Blazer foglight. You will then zip-tie the other end across the back of the air dam, and over to the driver-side Blazer foglight:

    

14. You are now ready to mount the foglights into the bumper. Just install the stock/modified brackets back into the stock location and re-secure the mounting bolts.
    
15. All that's left is to make sure they are aimed correctly. The Blazertech instructions have really good directions on how to properly adjust your foglights to the proper height. The 2200's and the 3200's differ in aiming.
