I have stumbled accross this forum because I am in need of some help. I was given the diagram below to use in my car, basically my AEM ecu can not handle locking up my torque converter and I need to isolate the ground useing a relay.

I tried this install last night and it does not appear to be working at all. The only thing it is doing is keeping the ECU powered up even after the key is off.

Any suggestions would be appreaciated.

Prove your connections, use a meter!

Whoever wrote the first diagram simply made a mistake in writing which terminals go where.

The second diagram, with the terminals labeled with pink numbers, should be correct.
