If you dont have the console please see my Delco listing. If your original resistor was a two piece that had a separate mounting bracket surrounding it and the seven terminal connector is at a 30 degree angle then the correct replacement is in my Delco offer.
If it does not match and your mounting tabs are in a different location please see my ac Delco listing for that one. Please match this to your original.
