Connector Assembly and Disassembly Information [pdf]

Are these AMP connectors compatible with other MegaSquirt products?

• No.  Even though other MegaSquirt products also use 35-pin AMP connectors, each connector has a unique keying, and each harness has a unique pinout.  These connectors are keyed to fit MS3-Pro ECU only and will not fit other products such as Microsquirt.  This is to prevent someone from accidentally damaging an ECU by using an incorrect harness.
