Any turbo guys use them on here? Can you just splice in a wiring harness or are there any with a near oem fit lol.

 

A lot of the import guys swear buy them. Personally it's a cool factor. They weren't installed from the factory so I doubt they are a necessity.

You have to wire them yourself. There are partial harnesses available for DSM's, Honda's and such but thats about it. They are not hard to install, that's for sure.
