Engine Management Systems (EMS) Reviews Check out this recent AEM ECU Extension Harness customer review: Tiffany D from Leechburg, PA says "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."
