8HP wiring kit

Sale price2.999,00 NOK
Installation kit:

This wiring kit is designed for 8HP transmissions running the Turbolamik controller.

The wiring kit is terminated in the transmission end only, and offers a low price, high quality alternative to the customers that want to do the internal/controller wiring themselves.

The cable for the main wiring kit is made to our specifications and features concentrically twisted Spec 55 wires with Kevlar lacing and Raychem DR-25 sleeving. 

The vulnerable Speed/analog wires are run in a shielded quad in order to isolate noise from the solenoid cables.

We have added extra wires into the cable that can be used for oil pan temp sensor, external speed sensor or reverse light output. (located near the transmission connector)

The transmission end is terminated with a genuine Kostal 16 pin connector.
