So I had another problem that may have been related. The daylight sensor was working almost backwards. In the morning when it was overcast and dim, the headlights were off. That afternoon when it was bright and sunny, they were on. Now that the I look at the first diagram it makes sense that there was power missing from the circuit. What is strange is that would work at all. That part I don't understand.

On the 02s the ign E circuit does not power the BCM so the light sensor would have been working. The BCM uses it to ground the circuit. My manual is off line right now, but I suspect it may have been in a default mode to make sure some type of front light was on.

Back in the 02 - 03 years DRLs were mandatory one of the reasons why we can't turn them off.

I'm starting this thread to help out all of the members who like me got frustrated with trying to find the correct information and instructions to the Under Hood Full Time DRL mod.

If any of you are like me, if you can't find something with three or four clicks you forget it, but this is one of the coolest mods and its pretty easy. These instructions are compiled from different posts and are only intended for 2002 Avs.

1. To play it safe, disconnect the Black Ground cable from the battery.

2. Standing on the driver's side of the truck, Remove the black curved bracket that connects the fender to the body.

3. Remove the Electrical Center Plastic housing. First the top, then look at the sides of the housing and find the tabs which hold it down. Angle the housing and unhook it from the tabs, and lift it off. This should reveal the naked fuse box which is the contents of the Electrical Center.

4. On the fender side of the fuse box is a locking latch. Push this tab towards the fender and this should unlock the fuse box. Then unhook the tabs at either ends of the side facing the engine. The fuse box is now loose and ready to be turned over.

5. There are different colored sections on the underside of the fuse box; we'll be operating in the green area. It is bolted into the box and it must be unscrewed. Loosen and remove the green connection block. Remove the two blue locking clips on both sides of the green block.

6. On the far right row, there are several wires, locate the double royal blue wire. Remove this wire from its current position and drop it down one (1) hole. Now the right side should have a double green wire at the top, followed by a single red, a single blue, a double purple, then the space just vacated and the newly relocated double blue wires.

7. Relock the green block using the blue locks. Screw in the green block back into the fuse box.

8. Test to see if the mod works. Reattach the Black Ground cable to the battery, and turn the key to the on position. (You don't have to start the truck. The DRLs should come on when the truck is in Park.

9. When everything works as you like it, lock in the fuse box, replace the cover and the top. Reattach the black curved bracket.

10. Sit back and enjoy the sense of accomplishment.

Use these pictures to aid in the modification. The first pic is of steps 1-4. The second pic shows the location of the double blue wires in the green connection block. This picture shows a red wire in the slot where we have placed the blue wires. The red wire is XRover's switch mod. For directions on the DRL on/off Switch, PM XRover.
