i4 Sumitomo (Denso) Primary Injector Harness (HT-186015)

The i4 Sumitomo (Denso) Primary Injector Harness (HT-186015) connects four injectors with Sumitomo (Denso) plugs to the injector breakout on a Haltech Nexus inline-4 main terminated harness, such as the Rebel K main terminated harness (HT-186402).

What it does

• Four Sumitomo (Denso) injector plugs, each labeled by cylinder
• Plugs into the injector breakout connector on the main harness, no splicing
• Lets one main harness suit different injectors: swap the sub-harness, not the harness

The Nexus Rebel K kit (HT-220206) comes with the Keihin injector harness (HT-186016). Choose this harness instead if your injectors use Sumitomo (Denso) plugs.

Fitment

• Haltech Nexus inline-4 main terminated harnesses, including the Rebel K main harness (HT-186402)
• The Nexus Rebel K ECU drives high impedance injectors only. Check your injectors before ordering.

What's in the box

• 1 x i4 Sumitomo (Denso) Primary Injector Harness (HT-186015)
