Our Hummer system is constructed much like all of our IFS systems with extended steering knuckles and high clearance crossmembers but the differences stop there. To properly address the H2’s fulltime transfer case we include a CV style front driveshaft with this system to provide smooth driveline operation. Also unique to this system is two 1/4” thick skid plates, one for the front differential and one for the transfer case. Rear lift on factory air bag H2’s comes from a super stout bag spacer while coil spring models receive replacement coil springs that are driver and passenger specific.

Step 1 Remove the driver’s side hood cover by prying upward with both hands.
Step 2 Remove the driver’s side windshield molding. Do not peel off the rubber seal or separate from roof molding.
Step 3 Remove 4 screws from driver’s side roof railing. Remove roof and windshield molding and set it down on the table.
Step 4 Measure 1” from the beginning of the roof railing and mark on the masking tape the spot to drill ½” hole for your harness.
Step 5 Install relays onto driver’s side engine compartment behind the battery, (See Step 6)
Step 6 Ground two short black wires leading from relays to screws holding the relays. Run yellow wires towards the corner of engine compartment.
Step 7 Run blue switch wire through the existing rubber grommet in the fire wall next to the relay’s location (Step 6).
Step 8 Pull both fuses out of fuse holders to protect from falsely activating the harness.
Step 9 Connect both red wires leading from relays to the battery’s positive terminal.
Step 10 Run both yellow wires with black wire alongside the windshield and up to the roof. Use electric tape to help hold down your wires.
Step 11 Continue with yellow and black wires on the roof. Set down the roof molding placing the wires in the molding cradle. Bolt the
molding down to the roof.
Step 12 Place left post of light bar inside roof railing. Mark 4” from beginning. Connect blind side of red wire to any hot wire under dash board.
Ex: Red wire leading from the break pedal.
Step 13 Insert the pins from yellow wires into the outside pin holes of the receptacle. Insert the pin from black wire into the middle pin hole.
Step 14 Slightly remove the top rubber seal on the top of the bar and secure with screws (provided).
Step 15 Repeat Step 14 on the other side of the vehicle securing down your light bar to the posts.
Step 16 Plug in the light bar plug into the harness receptacle. Close off both sides of the bar with cover and lock the key for safety.
Step 17 You are now ready to install switches. The easiest location is under the steering column. Mark two spots for your ¾” holes.
Step 18 Drill two holes. Snap both switches in place. Connect short red wires to one prong of each switch.
Step 19 Connect blue wire leading from relay through the fire wall to one prong on each switch.
Step 20 Connect the blind side of the red wire to any hot wire under the dash board. Ex: Red wire leading from the break pedal.

Slide Housing Bracket over bolt at #12 hole location (Photo 3), keeping the bracket between the cargo management rail and lock washer (Diagram 4). Fully tighten and repeat for the other side. Place the small Rubber Gasket (Photo 5) provided between the Housing Bracket and the bed rail (Diagram 6). Note: Place the notched end of the gasket on the bulkhead. Repeat for the other side. Place the Bulkhead Flange over the bulkhead rail (Photo 7). Insert the black plastic push pins to secure the flange (Photo 8).

This month you will receive two Cheap Tricks for the price of one! Although the pictures are of parts of a Hummer H1, this article applies equally to all vehicles with side-terminal batteries.

Picture 1 – Battery Terminal with Cover First, a little background about battery terminals and Hummers. The stock Hummer battery has side terminals. The cables are designed to “piggyback” as necessary to connect to both batteries. The late-model Hummer winch wiring harness contains these same “piggy-back” cable connections. Low-current accessories for the Hummer should be wired to one of the convenient power junctions under the hood or under the dash. This includes anything under about 60 Amps. Low-current accessories should not be attached directly to the batteries. What accessories draw more than 60 Amps? Winches and power inverters, mostly. Such high-current accessories should be connected either to the battery terminals, or (if practical) to the large studs on the starter motor.
