Part Recommendations For Flat-Towing A 2006 Hummer H3


Hi..have an 06 Hummer H3 with a round 6 male plug on the front of it. Also have an rv with a 4 pin male plug on it. How do I mate the two rigs together? Do you have an adapter that will work for this setup? Thanks.

In order to be able to flat-tow your 2006 Hummer H3, there are 5 items needed.

You will need base plates for the Hummer, a tow bar, safety cables, lighting for the H3, and most states now require a supplemental brake system.

The base plates I recommend are the Roadmaster Base Plates, part # 2505-3. When the front arms are removed the system is virtually invisible.

The tow bar I recommend is the Roadmaster Falcon 2 Tow Bar, part # RM-520. This tow bar has a weight capacity of 6,000 lbs.

For safety cables I recommend part # RM-643.

I recommend testing the 4-way connector at the back of your rv for function with a circuit tester like part # 3808. You will want to make sure your connector on the Hummer matches the connector at the back of your RV.

For the wiring on your Hummer I recommend you use a 12 V power source and cut the plug off the front of your H3. Then test the wires for function.

If the 4-way plug on your RV has 3 male pins and one covered pin I recommend part # HM48030. If the RV plug has 3 covered pins and one male pin I recommend part # HM48192.

If the plug on the front of your H3 is not for the brake lights, tail lights, and turn signals I recommend the bulb and socket kit, part # RM-155.

If your RV has Air or Air-Over-Hydraulic brakes I recommend Part # RM-9160-900002.

If you have hydraulic brakes on your RV, I recommend part # RM-9060-900002.

Both of these supplemental brake systems have a very involved installation, so I recommend having someone with a high degree of mechanical experience do the installation.
