Product Description
The EDGE PRODUCTS 98624 EAS VP44 TAP CAP is the clean, reliable way to wire-tap your VP44 injection pump on 1998.5-2002 Dodge Ram 2500/3500 5.9L 24V Cummins trucks. This dedicated tap cap gives your Edge Comp, Juice w/ Attitude CTS3, or other VP44 wire-tap modules a solid, sealed connection to the pump harness without sketchy splices or trial-and-error cuts.
Instead of piercing insulation by hand or guessing at the correct VP44 wire, the 98624 EAS VP44 Tap Cap uses a purpose-built cover and pre-terminated pigtail for a secure, repeatable install. That means less time under the hood, fewer wiring headaches, and a much lower chance of damaging your VP44 when adding serious tuning.
Key Features
- Designed specifically for VP44-equipped 1998.5-2002 Dodge Ram 2500/3500 5.9L 24V Cummins trucks.
- Provides a clean, sealed wire-tap connection for the VP44 pump harness.
- Ideal companion for EDGE COMP BOX and JUICE W/ ATTITUDE CTS3 VP44 tuning modules.
- Reduces install time versus cutting/splicing individual wires in the factory harness.
- Helps protect the VP44 from damage caused by incorrect or poor-quality tap attempts.
- Engineered to integrate with Edge’s EAS (Expandable Accessory System) architecture.
Fitment
The EDGE PRODUCTS 98624 EAS VP44 TAP CAP is built for VP44 pump applications on second-gen Cummins trucks:
- 1998.5-2002 Dodge Ram 2500 5.9L 24-valve Cummins (VP44 injection pump)
- 1998.5-2002 Dodge Ram 3500 5.9L 24-valve Cummins (VP44 injection pump)
- Fits both automatic and manual transmissions.
- Compatible with trucks using Edge Comp Box, Edge Juice w/ Attitude CTS/CTS2/CTS3, and similar VP44 wire-tap modules.
If your truck is a 24-valve 5.9L Cummins with a VP44 pump (mid-1998 through 2002 model years), this tap cap is the correct accessory to make a professional-grade tap connection for Edge VP44 modules.
How the VP44 Tap Cap Works
The factory VP44 harness is notoriously sensitive—incorrectly tapping the wrong wire, cutting too deep, or leaving an exposed splice can lead to intermittent issues or even a damaged pump. The 98624 EAS VP44 Tap Cap replaces the factory pump cover with an Edge-designed cap that:
- Indexes correctly over the VP44 harness connection.
- Provides a dedicated take-off point for the VP44 signal Edge modules need.
- Uses a pre-terminated pigtail to plug into your Edge harness for a secure, repeatable install.
- Maintains a sealed, OEM-style look once installed.
Paired with proper fuel supply (lift pump/pressure), EGT monitoring, and quality tuning, this tap cap supports serious VP44 performance while minimizing wiring-related risk.

Helpful Notes
- This kit focuses on the VP44 tap cap connection — it does not include a tuner/module itself.
- Always follow Edge’s install instructions carefully when accessing or tapping VP44 wiring.
- Pair with an Insight/CTS3 monitor and fuel pressure/EGT sensors to help protect the VP44 and pistons.
- Verify local emissions and usage regulations; many VP44 tuning features are designed for competition/off-road use.
Frequently Asked Questions
Will the EDGE 98624 EAS VP44 TAP CAP fit my truck?If you own a 1998.5-2002 Dodge Ram 2500 or 3500 with the 5.9L 24-valve Cummins and a VP44 injection pump, this tap cap is designed for your application. It will not fit 12-valve trucks or common-rail 5.9L/6.7L Cummins engines.
Do I still have to cut or splice any VP44 wires?
The purpose of the 98624 tap cap is to avoid crude splices and trial-and-error cutting. It provides a dedicated connection point for Edge VP44 modules, so you’re not guessing at wires in the factory harness. Always follow the official Edge wiring diagram for your specific module.
Which Edge modules work best with this VP44 tap cap?
The tap cap is commonly paired with EDGE 30305 COMP BOX, EDGE 30306 COMP BOX, and JUICE W/ ATTITUDE CTS3 or JUICE W/ ATTITUDE CTS3 VP44 applications. It simply provides the tap connection; the module you choose dictates power gains and features.
Is the VP44 tap cap install reversible?
Yes. Because the 98624 uses a dedicated cap and harness connection rather than cutting into the factory wires, you can remove the Edge module and tap cap later and return the truck closer to stock configuration if needed.
Do I need an Edge tuner to use this tap cap?
This part is specifically engineered for Edge VP44 wire-tap modules (Comp, Juice w/ Attitude, etc.). On its own, the tap cap does not change power or tuning — it is the safe connection point those modules require.
