Question and Answer

would any of your universal ecms work for a 1999 plymouth prowler? Jun 18, 2020
Will this wire harness fix a hyundai tiburon gt 2.7 and is it the complete set?Plug and play?Montrail T.Nov 10, 2020
Best Answer:Hi Montrail, This is a universal Engine ControlModule and not just a wiring harness. This is not vehicle specific. You missed providing the year of the vehicle for me to check if we have a wiring harness for the vehicle. It would be best to call the technical department of the manufacturer Holley at the telephone number 1-866-464-6553 to ask for the correct part number for the vehicle.
