The Sensor Module needs to be in a secure area, shielded from the elements. IE, keep it away from dirt and water – so do not install it under the hood. A great place to hide the module is behind the vehicle headlight switch. Start by removing the switch, done by prying it out with a screwdriver. Then pull the dash out with a firm tug. The dash is attached with metal clips.



Run the wiring from the senders through the firewall. There are many grommets to choose from in the Superduty. Here is one next to the PCM. If you have an automatic, another option is to use the grommet otherwise occupied by the clutch linkage.



A great place to route the wiring from the A-pillar to the Control Module is through the panel behind the dash. Find a secure area, and zip tie it down. There are mounting holes in the control unit, but using then in this situation would be extremely difficult.
