FITMENT
- For 2008–2010 6.4L Ford Powerstroke models.Covers EGR / DPF Plugs.
DESCRIPTION
Product Overview
-
When performing EGR/DPF deletes or installing custom tuning on 2008–2010 6.4L Ford trucks, several factory sensor connectors may no longer be used. Leaving these open connectors exposed to moisture, dirt, road salt, and engine bay conditions can lead to terminal corrosion and damaged wiring over time.
- The Ford Harness Plug Kit provides a simple way to protect unused factory connectors after tuning or emissions modifications. Designed for commonly disconnected EGT, DPF pressure, EGR, and related sensor plugs, these weather-resistant caps help keep connectors clean, protected, and organized for a professional engine bay finish.
Key Features
- Heat &Oil Resistant Construction: Made from durable automotive-grade materials designed to withstand engine bay heat cycles and harsh underbody conditions.
- Helps Prevent Electrical Corrosion: Shields exposed terminals from rain, road salt, pressure washing, and grime to help reduce corrosion and wiring issues.
- Harness Protection: Protects commonly disconnected factory sensor connectors after EGR/DPF deletes or custom tuning by sealing them against moisture, dirt, and debris.
- OEM-Style Clean Finish: Direct-fit caps snap onto factory connectors, keeping unused harness plugs protected and giving your engine bay a clean, organized appearance.
- Simple Plug-and-Play Installation: No cutting, splicing, or tape required—simply install each cap onto the matching OEM connector for quick protection.
FAQ
Q: What is the main purpose of this tuner harness plug kit?
A: When you install an EGR or DPF delete kit and flash a tuner on 6.4L Ford, several factory electrical connectors are unplugged. These dummy plugs snap onto those open harness ends to seal out water, dirt, and salt, preventing terminal corrosion and short circuits.
Q: Do these plugs eliminate Check Engine Lights (CEL) by themselves?
A: No. These are protective mechanical weather caps, not active electrical simulators. You still require custom ECM delete tuning (such as SCT, H&S, or EZ LYNK) to turn off emissions DTC codes and prevent limp mode.
Q: Which sensors are these protective caps designed to cover on a 6.4L Powerstroke?
A: They fit the disconnected factory connectors under the hood and along the frame rail, including the EGR valve, EGR temperature sensors, EGT sensors, and DPF pressure differential sensors.
Q: Is any electrical tape or zip-tie required to keep these plugs in place?
A: No. Each plug features a factory-style locking latch that snaps securely into the OEM harness connector housing, ensuring it won't vibrate loose even during extreme off-road driving.

Verified buyerRunning between three rig sites every week, was burning through DEF in about 2 weeks. Getting 6 weeks per jug now. Regen lockouts used to cost me half a day in the field, that's done with.
Chris D.
Verified buyerGot four trucks on the ranch, did this one first to see how it'd go. Eight months in, no codes, pulls hay like she's new again. Other three are getting done before winter.

Verified buyerTowing the boat down to the Keys used to kill me at 11 mpg. Got 15.4 last trip, same boat, same route. Pipe looks stock from the outside, none of my buddies even noticed it's gone.
Mike R.
Verified buyerHauled my horses from Fort Worth up to Amarillo last month, got 17.8 empty on the way back. Was running around 13 before. Pulls a lot better up the grades too, didn't expect that part.
Jason T.
Verified buyerUsed to go into regen every 280 miles when I was loaded down, now I'm pushing 580 with no regen at all. EGTs run way cooler too pulling the skid steer. Wish I had done this sooner, honestly.
Brandon L.
Verified buyerBought it used and the previous guy had wiped the delete history clean. Got everything put back the right way, ran the protocol, passed smog first try. Truck finally drives like it should.

Got questions?
The stuff that keeps you up at night before you commit. Answered in plain talk by guys who actually wrench on these trucks.
A full mandrel-bent stainless DPF and CAT delete pipe, EGR block-off plates and gaskets, DEF delete components, all mounting hardware and clamps, and your preloaded tuner with the custom tune for your VIN. We don't ship anything you don't need, and we don't leave anything out that you do.
No. The custom tune disables the codes the deleted hardware would otherwise throw. Dash stays clean. If a real fault code pops up after install, call our line and a tech walks you through it. Usually it's a sensor that got unplugged during the wrench work, takes 5 minutes to sort out.
We pull your VIN before we ship. Engine, year, trim, cab config, all verified against the kit. If it doesn't fit your truck, you send it back and we either ship the right kit or refund you in full. Fitment is on us, not you. That's why we call it a fitment guarantee.
Most of our customers do. Average install is 2 to 4 hours with basic hand tools, sockets, ratchet, jack stands. You'll get the step-by-step install video emailed after purchase and a 24/7 phone line if you get stuck. If you can change your own oil, you can run our protocol.
Real custom files. Built in-house by guys who've been turning wrenches and writing tunes on Cummins, Duramax, and Powerstroke platforms for years. Every tune is dialed to your year, your engine, and how you actually drive the truck. No outsourced generic tunes pulled off a shared drive.
Once we've got the base files for your platform, dialing it in for your specific truck takes about 20 minutes. Charging $300 for that didn't sit right with us. We'd rather give you the better experience and earn the call when your buddy's truck needs help.
You call us. Real diesel techs, US-based, picking up the phone. We help with install troubleshooting, tune adjustments, fitment issues, codes, anything. We don't disappear after the sale, and the line doesn't go to voicemail. Phone number is at the bottom of every email and on every page of this site.
Yes. The custom tune is reversible, flash the stock file back through your tuner and the truck reads as factory again. The only thing that's permanent is the deleted hardware itself, but most buyers in the diesel community see a properly executed delete as a value-add, not a deduction. We can also ship the OEM-style reverse plates if you want to put the factory exhaust back on for resale.
Lifetime warranty on the stainless delete pipe, no rust-through, no cracks, ever. 2-year warranty on the EGR delete plates, gaskets, and hardware. If anything fails, we ship a replacement same day. The tuner itself carries the manufacturer warranty through EZ Lynk or HP Tuners.
Orders ship from Fort Worth within 1 to 2 business days. Free express shipping anywhere in the lower 48. Most orders land in 3 to 5 days. You'll get tracking the second it leaves the shop.
