AEM ECU Extension Harness Reviews


ECU Extension Review

Reviewed By Tiffany D (Leechburg, PA) —10/30/2011 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.
