Let us take all the stress out of your conversion. We will convert your existing loom to suit whatever application you have. All of our looms retain the Subaru diagnostic, are fused up and are as plug and play as possible. To avoid any problems, our looms are all run on one of our test engines to ensure they are 100%, before they are sent out. If you have lost your Subaru key, don't worry - we can normally code a key to work with your loom.

We can convert most looms, including import turbo's H6 JDM European left hand drive. We are also working on a cost effective solution to the later can-bus engines. We can also build you a loom to suit a standalone ECU.
All our loom come with a gps speed signal sensor as standard unless we are converting the loom to be used with a Subaru gearbox and therefore wont need one, We can also provide a stainless steel mounting plate to help with a nice easy and clean install.
