Hi guys, I bought a full set of interior LEDs from HIDGUY and love them. In case you wanted to upgrade your rig, here is a how to. Bear with me…this is my first how to heh. Note: Check the polarity of the LED and mark them which way they work. If they do not light turn them over / rotate.
The Tools:

263510_560196461783_214201925_32028433_358710_n.jpg


1 Pocket screw driver (flat end was useful)
1 Philips screw driver med. Length.
1 Miniature 45 degree needle nose pliers
1 Knife (not pictured)
1 Sharpie (not pictured)

I started with the door lights. It was easy I put the pocket screw driver against the back of the housing (closest to outside edge) and just pried till they popped out. Pulled out the connector, pulled out the old 194 bulb. Installed the LED replacement noting the polarity. (Through trial and error). Checked if the LED lights up. It did so I was done. Found the 194 led base is slightly larger than the standard bulb. So I used my knife and cut out a small amount to make the diameter larger.

Pushed back into the door and done. Repeat on all doors.

Then I decided to do the roof lights. Again using the pocket screw driver I removed the housing lenses. Behind the white center lens there is a bulb and two Philips screws which hold the light up to the roof and also act as a ground. Do not remove the light yet! Take the LEDs and figure out which way they need to go to light up. Mark the direction with the sharpie. Then I removed the screws and brought the light down. I removed the bulbs. I found it easier to change the independent map lights with the light off the roof than when it was mounted. To change the map lights just hook one end then pull to the other and the tabs will create resistance and keep the LEDs in place. Replace left and right map light, mount the light back on the roof and install the center LED. Check operation. Reinstall plastic housing note that the housings have notches on them. Line them up with the appropriate side. Repeat for the rear and center dome light.

Next I went onto the front map lights. (This maybe slightly different for you) I do NOT have rear A/c, I have/had a roof console. (Mostly removed due to sunroof). Again using the pocket screw driver I removed the empty slot for the console. There is a screw holding it to the roof. There is also a screw just in front of the rear view mirror. Remove both Philips screws and bring the map light holder down. Unplug the lights. Separate the map lights from the console. 3 Philips screws. Plug the map lights back in and check LED polarity and mark it. Trust me it makes things easier. Insert the pocket screw driver through the light and push on the lens from the inside to push it out. Using the pliers gently grab the 194 bulb and pull it out. Install the marked LED. Turn the light on and it should light. If it does not light you may need to change the polarity, using the pocket screw driver you can push out the led from inside the housing similar to pushing the lens, just push the bulb out. Or you may need to bend the metal contact tabs to make good contact with the LED. Check the fitment and play with it. Eventually they will work. Once they work reinstall the lens by pushing it back it. Possibly use some super glue if your lens does not stay. (Mine worked without anything.) Reassemble the map lights and overhead console. Reinstall.

Which roof lights?

The center domes or the outside map lights or the front map lights??

Best thing to do is call HID guy, talk to either Oscar or Mario and let them know what bulb you want to replace. Our trucks came with a lot of different options.

When installing the door lights, I used a Tapered Reamer to open the hole up instead. Didn't want to slip with the knife and cut myself. lol
