I'm just looking forward to ice cold a/c this summer. Have you checked out Dakota Digitals fan controller. With the extra module, you just plug into the OBDII port to get your temp and shut off times. So no ugly adaptor or sensor to fool with under the hood.
Yes it stays. Picking up a splitter so I can still use my SCT. It just needs to read the info. Shouldn't be any issue concerning any edge functions
It's not for a display, its just to control the fans with out putting a temp probe or sensor with in your cooling system. It pulls the info from the ecm for CHT and VSS etc, that it needs. Cleaner install.
