Does ECU in Firestone Wireless Air Command System have to Face a Certain Direction
Question:
Does it matter which way the ECU faces, air line holes facing up or down? The location I have chosen there is not much room for the air lines and they bend sharp. I have it located on the inside of the frame rail below the drivers seat. This is installed on a 2011 f250 XLT. I am using the firestone mounting plate. Or do you have a better location? I thought of putting it on the outside of the rail, but I am tryng to protect it from mud, ice, snow. Thanks

The only mounting requirements for the ECU in Firestone wireless Air Command system # F2581 are as follows:
Mount close enough to the Air Compressor to allow Wire Harness connections to reach.
Allow room for Air Line Tubes to connect to the air fittings on the ECU.
Allow room for the 14-pin ECU connector to connect to the ECU.
Allow room for the Air Line Tube to run without sharp curves or bends.
Using supplied fasteners shown in Step 3 is recommended. If no other mounting option is available,
see the sidebar on Step 2 for using the Large Nylon Ties.
Select a location that is solid and secure on the body or frame of the vehicle, away from any moving parts, electrical or any other lines.
The mounting location will need to meet the above criteria. You will want to avoid sharp bends so it does sound like you will need to move it some. There are no requirements regarding which direction the ECU faces.
