Features & Product Details

HKS has developed their Turbo Timer Harness for those of you who want a clean, and complete installation.  Installation of this turbo timer harness is fairly simple by just getting access to your ignition harness, unclipping them from the factory provisions and clipping them back into place in the HKS harness, while clipping the other end back into the factory provision.

The other clip will be for the power to the turbo timer. Afterwards you can enjoy the turbo timer, and extend the life of your turbocharger.

The harness makes install a snap, works nice, and has quality plugs; especially since it eliminates the need to splice wires in the ignition. Well worth the $$$.
