2010 Hummer H3T Wiring Harnesses

Genuine GM wiring harnesses for the 2010 Hummer H3T, at wholesale prices. Harnesses carry the exact connectors and pinouts the modules expect, and they change with option content and build date. Four-door pickup version of the H3, built for only two model years.

Symptoms to look for

Rodent damage, corrosion at a connector, or a repair after collision work. On a mid-size pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.

Buying OEM, briefly

• GM stands behind it. The wiring harnesses warranty comes from the manufacturer, not from us.
• Priced below the dealer. Wiring Harnesses at up to 40 percent off list, with no membership.
• Factory sourced. These wiring harnesses are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical wiring harnesses numbers for you.
• Ships from Dallas. Wiring Harnesses ordered by 3pm Central go out the same business day.

Ordering correctly

Original tooling means original fit, which matters most on anything that has to align with a neighboring part. Our VIN lookup is more accurate than any public catalog. Use it before you check out. In stock orders placed by 3pm Central ship the same business day from our Dallas warehouse.
