Hi
I have a 2005 Supra Launch 21V with the 5.7l Indmar and have just upgraded my Perfect Pass Pro (paddlewheel) up to Perfect Pass Stargazer (GPS) DBW.

The Servo motor is deleted and I have connected directly to the main wiring harness, but I cannot find the ALDL PLUG to connect the Grounding plug.

The system fires up and displays RPM but will not lock onto speed doing the "Control Test"

Can anyone assist with location of the ALDL plug? or a way around it.

Thanks in advance.
