Description

This is the same wiring harness that's included in our Curl Control Cold Air Intake kits for the 2012-2015 9th Gen Honda Civic Si. The extension is approximately 22" long and fits between the battery terminal and the battery sensor wiring harness. This is an essential item when relocating your battery. Or, if you need to extend your OEM harness, like when placing the battery in the trunk, this is a great way to make a custom extension without cutting the OEM wiring harness. These fit the 2012-2015 Honda Civic Si. It allows the battery sensor harness to be extended as much as 22" without cutting any OEM wires. Each harness has a durable, rubberized, braided sheath for abrasion resistance and heat protection.

George ★★★★★

Relocating the battery on my Si made the stock sensor harness way too short, but this extension clicked right into the OEM sensor and reached perfectly with no splicing. The length is spot-on for a trunk or bumper mount setup, and the connectors feel solid. Much easier than trying to extend the fact

Penelope N. ★★★★★

Bought this for my 9th gen Si after moving the battery to the trunk, and the OEM sensor clicked right on with no trimming. Length was spot on to reach the new spot without stretching the wiring.

Edward C. ★★★★★

Relocating the battery for my turbo build left the sensor plug way out of reach, and this extension clicked right into the OEM sensor without any splicing. The 22" length gave me just enough slack to route it cleanly along the frame.
