Extend the range of your electronic-tuning endeavors with the AEM ECU Extension Harness. Instead of building a do-it-yourself harness like those shade-tree hacks on the forums, turn to AEM for an ECU extension harness that plugs right into your vehicle with original-factory connectors.

Having the AEM extension harness on board makes it easy to add turbo timers, data loggers and other auxiliary electronics that would otherwise require cutting into your factory harness. You can also troubleshoot your ride from outside the cockpit and easily remove or swap old electronic devices.

Crafted specifically for your vehicle's wiring harness, the ECU Extension Harness plugs right in with a perfect fit, and AEM designs it to work with most engine management systems. Best yet, your AEM ECU Extension Harness is backed by a 1-year warranty.

ECU Extension Review

5 of 8 people found the following review helpful.
Ease of Installation

Reviewed by Tiffany D (Leechburg, PA) — Oct 30, 2011 7:18 AM

The unit is well built. I used this unit to install a performance chip that required splicing into the ECU wiring. I spliced into this unit instead then plugged it in between the stock ECU wiring and the ECU. It installed without any problems. Wiring is solid and not issues with connections.
