Installing a Grounding Kit for Nissan Titan/Armada
(5) ground wires 4-24 and 1-12" (for 4WD only)
(3) zip ties
(2) ½-20 nuts
(1) ½ lock washer
(1) ½x1 bolt
7/16" open wrench
1. Install the first 24 wire on the negative battery terminal using one of the ½ nuts. You will need to tighten the nut down with the 7/16 socket.
2. You will attach the other end of this cable under the passenger side of the wiper cowl. In order to do this pull up on the outer edge of the cowl and then remove the 10mm bolt. Place the terminal between the metal of the frame pieces and tighten the bolt back into place. It is recommended, but not required, to sand the paint from this area and apply some dielectric grease. This will help ensure a better metal to metal connection and keep the unpainted area from rusting.
3. Next take one of the zip ties and secure the cable to the frame using the existing hole.
4. To install the second 24 cable, remove the 12mm bolt on the driver side fender wall directly behind the airbox inlet.
5. The other end of this wire will attach to the bracket on the driver side of the engine just behind and below the intake tube. You will need a 10mm socket for this bolt.
6. Zip tie the cable to the bundle of cables located behind the air filter housing.
7. The third wire to be installed is the 24 wire. Attach it using the bolt, washer, and remaining nut to the inner lip of the battery tray just behind the factory ground.
It may be easier to put the bolt through from the bottom, then put the ring terminal, washer, and nut on from the top.
You will need a 7/16 socket and 7/16 wrench. It is recommended, but not required, to sand the paint from this area and appy some dielectric grease. This will help ensure a better metal to metal connection and keep the unpainted area from rusting.
8. Run the cable down so that you can reach it from under the truck to attach to the alternator.
The remaining steps will be done UNDER the truck.
9. Locate the factory ground connection on the alternator and remove the 10mm bolt. Attach the other end of the cable you secured to the battery tray.
10. Now slide under the middle of the truck and remove the 10mm bolt from the bracket on the driver side of the transmission and attach the last 24 wire.
11. The final attachment point is the factory ground location for the exhaust. Remove the 10mm bolt and attach the other end of the final grounding strap.
12. It is also recommended to drill a hole large enough for the last zip tie to pass through into the heat shield on the driver side to secure the cable with so it doesnt swing loose.
An alternate zip tie location for 4WD trucks is above the transfer case. There is already a bracket with a hole in it, this would allow you to avoid drilling in the heat shield.
FOR 4WD ONLY
13. Attach one end of the 12" cable to the exhaust ground. This is the same location as in step 11 with the 10mm bolt.
14. The other end of the 12" cable will attach to the back side of the transfer case. This is also a 12mm bolt.
That's it, you have successfully installed a grounding kit.
