My car has a manual boost controller and a Turbo Tweak chip, PowerLogger, etc. I'm looking at adding Caspers 100psi fluid sensor to log fuel pressure and it has 3 wires in its harness (power), (ground), (signal), pretty simple. The factory boost solenoid is long gone and the wiring harness just sits in the engine bay so I thought I'd put it to use by using the 12 volts from that part of the harness, using the ground wire to send the signal into the car and cut/redirect that voltage it into the power logger.
So three questions:
1) Will redirecting the ground control wire from the waste gate solenoid cause any problems? (again I don't use the factory unit, it's just unplugged laying around in the engine bay)
2) Any problems using this 12 volt source?
3) Other than adding a ground is there a good ground in the harness close to the boost solenoid?
Finally, when I swap the motor for the built one I plan on cleaning up some previous very poorly done wiring by the previous owners & at that time I will re-run and re-loom this sensor input so I don't think this is long term.
Thanks!
