Derringer Hardware Differences
The Derringer is produced in two different form factors.
(PN 61312) is an over-molded design with a pigtail 8-pin connector.
(PN 61313, 66797, 66798, 66799) is housed in a hard plastic case with an integrated 12-pin connector. The function and operation and capability of the GENERATION 1 Derringer and GENERATION 2 Derringer are identical; just the looks and feel of the module have been revised.
The images shown in this manual are for installation of a GENERATION 1 Derringer. The process for installing the GENERATION 2 is identical.
Section 1: Remove Components
1. Before beginning, disconnect the negative terminal of the battery.
2. Once the battery is disconnected, remove the engine cover.
2014-2018 Ram 1500 – First remove the oil cap. Then, lift up at the front to release the rubber socket mounts and pull forward to release from rear mounts. Reinstall oil filler cap.
For 2020+ vehicles remove the two 10mm bolts holding the cover on.
NOTE: If installing in a 2014-2018 Jeep Grand Cherokee, skip steps 3 & 4 and proceed to step 5.
3. Remove the intake hose.

Using the 8mm socket, loosen the hose clamp on one end of the intake.
There is a clamp that’s partially covered by the lip of the firewall.
Remove the third bolt attached to the bracket.
5. Disconnect the closed crankcase heater ventilation connector.
6. Squeeze the clamp at the base of the crankcase breather hose to disconnect it.

9A. Using a flathead screwdriver or pick, pry the metal retaining clip up until it clicks out.
10. Gently slide the duct off the elbow and remove the duct.
11. Move the sound deadening foam out of the way so you have visual access to the fuel rail pressure sensor.
12. Determine the orientation of the FRP sensor.
Clocking the sensor can determine how difficult the remaining steps will be.
From 9 to 3 o’clock – you should be able to easily unlock and disconnect the sensor.
Locked at 6 o’clock – this will be the most difficult orientation.
Once you’ve made the orientation of the sensor, disconnect the MAP sensor.
13. Using a flathead screwdriver, you can see the locking tab on the MAP sensor through the bracket.
Unlock the tab and squeeze the sensor to disconnect.
14. Remove the turbo outlet elbow coming off the turbocharger.
Using the T-30 Torx, access the two bolts on the bottom of the flange of the elbow.
Remove the two bolts and remove the elbow.
15. Disconnect the air temperature sensor on the backside of the elbow by sliding the red locking mechanism back and depressing the tab and pull the connection apart.
16. Now it’s time to disconnect the fuel rail pressure sensor.
Verify the orientation of the sensor.
17. The locking mechanism is hidden on the underside of the sensor.
You’ll need to slide the locking mechanism back. Then squeeze the tab to release.
Once you hear and feel the click of the locking mechanism, you can squeeze the tab and pull the sensor off its housing.
Use a small flathead screwdriver to keep pressure on the sensor as you disconnect it.
18. Set aside the disconnected sensor, as you will be plugging it into the Derringer.
