All H&R ETS modules are plug-and-play, with no wire cutting and splicing or mechanical wrenching necessary. This means that no modifications to your factory wire harness are required and the module looks like a factory installation. H&R ETS modules come with all the parts required for installation. The ETS unit is easily removed whenever you want to return your car back to factory specification.
