For Titan's not equipped with the Tailgate Cargo Lights that are included in the Utility Bed package, this mod may be of interest. For approximately $20 I installed a set of lights at the rear of my bed which lights up the back of the bed and tailgate area. These lights will function exactly the same as the original cargo light: 1)when opening any of the doors, 2) when pressing the unlock on the keyfob, or 3) when turning on the cargo light via the dash monted switch.

Materials:
2 Ea. - Blazer #C455C, 20-3489 I got mine at PepBoys.
15 ft. - 16 Ga. Wire
4 Ea. - #10-24 Nuts/Bolts
1ft. - Heat Shrink Tubing
1 Can - Duplicolor Spray on Bedliner (not required)
1 - Scotchlok Splice
2 - 1/4" Rubber Grommets
1 Roll - Electrical Tape
10 - Cable Ties

Tools:
1 - 1 1/8" Hole Saw
1 - Drill
1 - Wire Stripper/Cutter
1 - #2 Phillips Screwdriver
1 - Small Pair of Pliers
1 - Soldering Gun
1 - "Scotchlok" Splice
1 - Drill Bit assortment

Installation Time:
1.5 Hours +/- depending on experience with electrical systems. Took me longer cause I was "winging" it. Hopefullly these instructions will help others.

Difficulty:
2 of 5. It's not an easy task taking the drill and hole saw to your precious truck!! Just be careful when cutting/splicing into the factory wires and you should have no problems.

Notes:
-It's not necessary to coat the outside chrome finish with bed liner. I did so to clean up the looks and get rid of the chincy chrome finish.
-I did not disconnect the battery during the install, nor did I pull the 10A fuse located in the fuse panel on the passenger side dash. This did not present any problems during the installation.

1. Remove Left and Right Taillights
2. Remove the "Kick Panel" from Passenger Side Rear Door Area. Lift upward on the front most portion, then slide forward and it comes right off.
3. Locate the LIGHT GREEN wire that is contained within the protective outer wrapping beneath the kick panel.
4. Run a wire (your choice of color) from the Passenger Side Taillight down through the bed, along the frame rail to an area just below where the LIGHT GREEN wire is located on the rocker panel. I used a BLACK wire because that is all I had. Typically, a RED or WHITE wire should be used. Secure with cable ties.
5. Drill two 5/16" holes to accommodate the 1/4" rubber grommets. One hole down through the top of the rocker panel, and one up through from the bottom.
6. Place 1/4" Rubber Grommets in the holes that were drilled in step 5.
7. Thread wire through the two rubber grommets. I used a wire coat hanger for assistance.
8. Using the Scotchlok splice, splice the newly ran wire into the existing LIGHT GREEN wire. Protect connection with electrical tape. Some might suggest cutting/splicing into the wire, or even soldering the connection. Fortunately, I had luck using the splice.
9. Using the 1 1/8" Hole saw, locate area on bed to drill hole for new lights. Drill holes in both Driver Side and Pass. Side Bed areas.
10. Prior to installing the new light housings, the tailgate cables need to bent inward slightly to avoid contacting the newly installed lights when the tailgate is closed. This will prevent cables from crushing the light housings.
11. You can now place lights into the bedside. Using existing holes in the light housing, locate where your mounting holes need to go and drill those holes.
12. Fasten light housing's using the #10-24 Bolts/Nuts, light housing might need reemed for clearance.
13. Run a wire across the back of the bed from one light housing to the other. Secure with cable ties.
14. Wire lights as shown in the attached schematic. I chose to solder all of these connections. Note that a short "jumper" might be required to connect the ground wire from the new lights to the BLACK ground wire for the brake lights depending on where you tie in at.
15. Enjoy.
