Wiring A Boost Selenoid

[Canadian 32]

Ok so I need to know how to wire up a boost selenoid on an RB20DET (r32 gts-t). The kit i have is for my PowerFC, before anyone says just unplug the stock and plug in the new one.... my car does not have a stock selenoid. So I need to know how to do it from scratch. The only thing I am having a problem with is wiring it up, everything with the hoses is all good (just replace the one from the wastegate actuator and run it into the selenoid, and back to the intake). Any help would be great. thank you

its covered in the powerfc faq (in my sig) it details the pinouts for the port and what wires you need

its basically just ground and power, you cant get it wrong really.

the map sensor needs power, ground and signal. so its two parts

#1 solenoid

#2 map sensor

both into the 5 pin boost kit port on the PFC

oh ok, thanks man. I had a couple people tell me i need to somehow run a wire from my ecu and so on. so just power(acc) and ground. And I have already installed the MAP sensor and its working fine. So if the selenoid isnt attached to a signal or anything how does it work? sorry im new to this stuff and just want it tall figured out before i go ripping things apart. thanks again

you need to run the solenoid ground wire to pin #25 on the ecu pinout (double check what wire #) pretty sure its 25

the PFC will switch this ground on and off to control the solenoid. this assume you have 3 pin boost kit port (rb25 style)

if you have rb20 ap engin version which is 5 pin kit then you need to find out which wire it is on the 5 pin socket and run it off there

Ya I have the 3-pin. so I just tee the ground into to the #25 (solenoid valve control.....) and the power to a near acc and im set eh. thanks a ton.
