| Just use any switched power source to power a relay. From AEM Installation Manual: Operating Voltage: 12VDC Operating Frequency: 31hz Duty Range: 10 to 90% Max Pressure: 120 PSI Electrical Connection: Polarity is unimportant. Hook one wire to switched 12 Volts and the other to the AEM EMS’s PW2 output or the driving devices boost control line. NOTE: on the SRT4 EMS 30-1510 PW2 outputs +12V. Hook up one wire to PW2 and one wire to ground. If you are not sure please refer to your EMS instructions/pin out sheet and verified the polarity output on PW2. When energized, ports 1 & 2 are connected, when de-energized, ports 2 & 3 are connected. The port numbers are clearly noted on the solenoid body. They also note:
Port 1: Sintered Muffler (would have come with the kit) Port 2: Wastegate Port 3: Boost Pressure
