Fan Speed Control
Photo Cell for Sunlight
Does that sound about right? Is it better to get parts from the '98 and newer ones?
Add the sample ducts and elbow for the interior sensor, the EATC vacuum harness, some wire, a few connectors and a relay or two. Just to be clear, the EATC mod requires replacing the Blend Door Actuator
(motor and gearbox), not the Blend Door itself.
Any 2nd gen (95~01) Explorer EATC can be made to work but the 98+ version has a green display (instead of blue) and that would match a stock 99 Ranger dash better.
Don't forget to cut connector pigtails from the harness for the EATC head unit and every other electrical component. Without these, wiring would be a nightmare.
Follow John's How-to
exactly for your EATC/Ranger combo and the install should go well.
