Heavy-duty diesel tuners, this one’s for you.

If you need to bench tune a Detroit Diesel ECM, this bypass breakout cable from Konnect Kables is a lifesaver.

It’s specifically designed for DDECIII and DDEC IV (DDEC3 & DDEC4) ECUs.

No more messing around trying to power them up on the bench with a bunch of alligator clips.

This harness makes it plug-and-play.

It’s a heavy-duty/commercial vehicle tool built to last, and it comes with a 1-year warranty.
