We have 6 different harnesses available. Different routing, power wire options, and wire/loom.

*Race-Grade Version – Uses Raychem DR-25 loom and upgrade TXL Wire with nylon braid for increased strength.

*Street-Grade Version – Uses standard heat-shrink tubing and TXL Wire.

*Routing Option –

-OEM Routing is ideal for RHD and Mid-Engine setups as the harness splits on-top of the trans.

-Tucked Routing harness runs over the valve cover and into the firewall by the oil pressure switch. This will not work on RHD or Mid-Engine cars.

*Power Wire Option – Integrated Power Wire adds an extra power wire to the harness. This will give you a simple way to run power from alternator to starter (Then daisy chain to alternator). This does add some size to the harness and reduces flexibility slightly. The fuse box must be close to the shock tower or under the dash. RSX/EP3/K-Swap EM2 must run without power wire.
