You are going to need a kit like the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 for your 2007 Hummer H3. This uses didoes which get spliced into your factory wiring. We do not have a plug and play harness for your H3.
Also you are going to want a Charge Line # RM-156-25 to maintain the charge on your H3's battery and prevent your Supplemental Braking System # SM99251 from draining the battery. view full answer...
