ThatSupraGuy Posted February 6, 2020 Report Share Posted February 6, 2020 Hi all just wondering how to wire in a boost solenoid to a supra link pnp? Can it be wired in using an expansion loom? I'm doing 2jz na-t so there is no factory boost control. Thanks Quote Link to comment Share on other sites More sharing options...

Unfortunately there are no spare aux outputs on the expansion connector (well only aux 9 but this can only be used for E-throttle). Easiest option would be aux 4 which is pin B60. So connect one of your solenoid wires to B60 and the other wire needs to go to a 12V supply that is only live when the ign switch is on.

0x33 Posted February 7, 2020 Report Share Posted February 7, 2020 SupraLink was designed around US/EU spec twin turbo. You will find that on an NA supra loom there is no pin on B60 from factory. So what you will have to do is depin another pin from somewhere else on the harness, put that into B60, then proceed to do your wiring to do the boost solenoid.

ThatSupraGuy Posted February 8, 2020 Author Report Share Posted February 8, 2020 So I could potentially use the pin from the factory o2 sensor as I have a wide band wired in with an expansion loom and just re pin to B60? Thanks alot for your help, really appreciate it. Quote Link to comment Share on other sites More sharing options...
ThatSupraGuy Posted April 9, 2022 Author Report Share Posted April 9, 2022 Bringing up an old thread. What kind of voltage should I be getting from ecu signal wire to Mac solenoid? I have battery voltage which is switched on power wire and then 11.5v on the ecu wire when the key is on. Having an issue where the ecu is not shutting down but when unplugging the Mac valve it will... Thanks. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 9, 2022 Report Share Posted April 9, 2022 That means the 12V supply to your boost valve is not ign switched. The 12V to that solenoid needs to turn off with ign. Quote Link to comment Share on other sites More sharing options...
