Find your harnessA 5.3L badge alone does not identify the right harness. Before ordering, confirm engine year and code, 24X/58X configuration, drive-by-cable or drive-by-wire, transmission model/year, ECM/PCM, injector connector style, MAF and alternator connections. For drive-by-wire swaps, also confirm the pedal and any required TAC module.
Standalone wiring does not mean every supporting component or programming service is included. Review the selected listing and confirm what your build still needs with HPI.
1997–2006 LS1; drive-by-cable; T56, manual or non-electric automatic transmission. EV1 connectors; request the appropriate EV6 or Delphi adapters in order notes if needed.

View harness & orderWhether your project is in Calgary, Edmonton or elsewhere in Alberta, start with your exact engine and transmission combination. Send HPI those details before ordering if you are unsure which harness matches. We also welcome builders in Ontario, British Columbia, New Brunswick and elsewhere in Canada.
Choose the listing designed for your transmission. The featured 4L80E versions include an adapter and require the described two-wire pinning step; do not assume the standard 4L60E listing is interchangeable.
Where the product listing offers adapters, specify the correct connector type in the order notes. Check the selected listing’s inclusion and ordering instructions before paying.
