7.3 Powerstroke PCM Terminal Repair Service

Stop guessing whether your chip connection is the problem.

On 7.3 Powerstroke trucks, the PCM’s rear J3 port is where a performance chip plugs in. From the factory, that circuit board is coated with a conformal layer to protect against moisture. That coating has to come off before a chip will work. The trouble starts when the coating—and the solder under it—gets scraped away. Bare copper oxidizes, contact gets weak, and the truck starts acting up.

The classic symptom: the truck dies while driving with the chip installed, then runs fine once the chip is removed. Other owners see hard starts, intermittent cutouts, or a chip that never quite “takes.” Left alone, a bad connection can also damage the PCM or the chip.

This service rebuilds those chip terminals the right way. Damaged material is cleaned off and the contacts are professionally re-soldered so the chip has a clean, consistent electrical path. It’s also the better option if you don’t want to prep the terminals yourself before installing a chip.

This is a terminal repair / re-solder service only. It does not include full PCM testing or a rebuild unless you add those separately.

Who this is for

Trucks that stall or shut off only with a performance chip installed
PCMs whose rear terminals show bare copper
Owners who over-cleaned the J3 port with a brush or pad
Anyone installing a chip who wants the terminals prepped correctly the first time
Used or unknown-history PCMs before a chip install

What we do

Inspect the J3 chip contact terminals
Remove remaining coating, oxidation, and damaged solder
Re-solder the contacts for a proper chip connection
Clean the work area so the port is ready for install

How it works

Order the service.
Print and fill out the PCM shipping form and put it in the box.
Remove the PCM from the truck. Do not ship the plastic mounting bracket.
Pack the PCM tightly in a rigid box with padding. Customer is responsible for shipping PCM to us.
We repair the terminals and ship the PCM back.

Packing note: Use a sturdy cardboard box and plenty of cushioning. Padded envelopes are not enough. Damage from poor packing is the sender’s responsibility.
