EZ Lynk Installation
ATTENTION!68RFE Relearn ProcessIf your 2010 Ram is equipped with the 68RFE automatictransmission, you must perform a re-learn procedure each timethe ECM is flashed, even if you aren’t loading transmissiontuning. Failure to do so will cause premature transmissionfailure. To perform the procedure after the ECM is flashed, drivethe truck and apply no more than 30% throttle for at least 2530 miles. It is important that the transmission shifts up anddown as much as possible during this period. NOTE: The 25-30miles is to re-establish the CVI values. It is common for thesetransmissions to take 400-500 miles or more to settledown. Sustained highway speeds should be avoided for the first25-30 miles. If you purchased a tuned TCM for your 2007.52009 68RFE equipped Ram, you must perform the same relearnprocess upon installation of the TCM.

Cummins SOTF Switch Install1. Disconnect negative battery terminals.2. Route the switch wires through the firewall and locate the crankcasepressure sensor. On the 6.7L Cummins, it’s located on the top driver’sside of the valve cover underneath the wiper cowl. On the 5.0LCummins, it’s located below the oil fill cap.3. Insert the switch wires into the supplied connector following the colorcoded markings. The red wire inserts at the red marked slot, the blackwire inserts at the black marked slot, and the white wire inserts intothe remaining unmarked slot. You’ll hear a click when they’re seatedinto the connector. Tug on the wires to ensure the wires are properlyseated.4. Plug the switch connector into the crankcase pressure sensor’s wiringharness.5. Mount the switch in your desired location.6. Reattach the negative battery terminals and drive the vehicle to confirmproper switch function after the SOTF tune is installed and thetransmission relearn procedure (if applicable) is complete.
LML Duramax SOTF Switch Install1. Disconnect the negative battery terminals.2. Route the switch wires through the firewall and locate the ECM. The ECM islocated on the front driver’s side of the engine compartment next to thedriver’s side battery.3. The ECM has 3 connectors. One is blue, one is black, and one is grey.Carefully unplug the GREY connector.4. With the connector in your hand, remove the zip tie holding the protectivecap and remove the cap.5.

Using a pinremoval tool, remove the yellow wire and secure to the harness usingelectrical tape. 2012-2016 year models will have a plastic filler pin ratherthan a wire. Using a small tool such as a drill bit, press the filler pin outof the connector.7. Insert the yellow wire in pin slot #11. Once inserted and seated, tug onthe wire to ensure it is secure. Insert the black wire in pin slot #35 andconfirm it is secured in the connector.8. Reassemble the connector in reverse order. Install the switch in yourdesired location.9. Reattach the negative battery terminals and drive the vehicle to confirmproper switch function after the SOTF tune is installed and the transmissionrelearn procedure (if applicable) is complete.
6.7L PowerStroke SOTF Switch Install1. Disconnect the negative battery terminals.2. Route switch wires through the firewall and locate the fuel temperaturesensor near the fuel filter housing. Unplug the factory harness from thesensor.3. Using the supplied taps, tap the switch wires into the green and greenwith white tracer. Polarity does not matter.4.
