I was a little sceptical until I saw in it the metal! They use the patch harness so the car still functions like it did factory. You can purchase a HKS F Con V Pro with a universal wiring harness if you desire. They have been installed on the likes of Porsche's and other Euro vehicles that they don't supply a harness for. Have a look at the spec sheet -
