OK I reread your post, it is obviously a wiring problem, not the hoses.
The boost control needs switched 12 V and PW2 output. The output for PW2 (pulse width 2) is pin 2H as you said. This pin should connect to the TEN terminal at your diagnostic connector. Running another wire to the ECU would not change anything. The wire is light green/yellow.
From the manual:
"The AEM EMS has a very comprehensive and flexible boost control circuit. Using a pulse width actuated solenoid, boost can be controlled by vehicle speed, throttle position against rpm, and a switch input for low and high settings. At this time, AEM recommends the 3-way GM solenoid (PN 1997152).
The first thing to do is determine what frequency at which the solenoid needs to be operated. This information is typically provided by the manufacturer of the part. If you are using a plug n' play with a factory boost control solenoid, this comes pre-configured by AEM.
The PW# 2 output pin needs to be determined when installing a boost solenoid. Refer to the Application Notes for the pinouts of the specific EMS used. This information can also be found on the AEM EMS forum (Offical AEM Air Induction Systems and Performance Electronics Site - Home Page
). There are two wire connections for a boost solenoid and there is no polarity. One wire connects to 12 volt switched power and the other will connect to the PW #2 output on the EMS."
