No, no plug n play efan setup is available as the stock wiring can't handle the amperage efans need thus the reason everyone runs a relay harness. You still have to patch the ECM with HPTuners or EFILive to make it function. This kit has 2 pings that plug into the ECM connectors for fan signals and pulls power via relays directly from the battery. I'd recommend a PCMofNC Big 3 upgrade at the same time, if for no other reason you need the battery terminals to bolt the fan harness to.This is all plug an play correct for 2008 Saab 9-7x aero/TBSS? We just plug the harness into existing harnesses under the hood. Is that correct?
