7.3 Powerstroke PCM Port Chip Prep Pen

Make chip installs clean, consistent, and low-risk. This specialized prep pen delivers a controlled solution that dissolves the factory conformal coating and silicone residue on the J3 (rear) terminals of your 7.3L Powerstroke PCM—so you get reliable contact without the usual guesswork or damage risk.

Why it matters

When installing a performance chip (Hydra, TS, Edge Revolver, etc.), the J3 port contacts must be fully cleaned. Factory coating left behind causes poor connection, no-starts, intermittent shutdowns, or worse. Over-aggressive scrubbing with Scotch-Brite or brass brushes can strip the tinning and expose copper, creating future oxidation and connection problems. This pen removes the coating thoroughly while helping protect the underlying plating.

Key benefits

• Quickly dissolves coating for a near-perfect clean every time
• Greatly reduces the chance of under-cleaned or over-cleaned terminals
• Safer alternative to aggressive abrasive pads and brushes
• Enough solution for multiple PCMs
• Simple, controlled application that takes the stress out of the most critical step of a chip install

Fitment

1994–2003 Ford 7.3L Powerstroke (all PCM applications that use the J3 service port)

How it’s used

Remove the PCM, split the case, apply the solution liberally to the terminals (one side at a time), let it dwell ~10 minutes, gently scrape and wipe the softened coating, and repeat as needed until the contacts are clean and shiny. Full step-by-step instructions are provided.

Ideal companion for any plug-in performance chip installation. Take the anxiety out of PCM prep and get a solid, reliable connection the first time.
