Boost Pressure Sensor For Apexi El I Gauge

[made_guy]

Does anyone know if you can buy the pressure sensor (and the little fliter thing) needed for an Apexi EL (series I) boost gauge?

its the pressure sensor on page 4 of this manual http://www.apexi-usa.com/pdfInstallation/8.pdf

I'm guessing it's interchangeable with ELII gauges too. Also if anyone that has installed one could give me a heads up on installation issues it would be much appreciated (though it looks pretty straight forward - provided you have a pressure sensor...)

By the way, i bought this gauge yesterday 2nd hand but haven't been home to have a look in my engine bay - was just trying to figure out how much time it would take me by looking around for 'guides/instructions' and noticed the reference to this pressure sensor... :S

hmm ok, so i got home and had a look under the bonnet and see that the line coming from the plenum is going to a little box with the same sort of plug as indicated in the manual (link above)

this box:

can i just plug my gauge into this? or is this leading to the ecu or something?

found out it's actually the MAP sensor and have had one person tell me its fine to plug straight into that, another saying it won't be suitable for an aftermarket gauge....

i'll just splice into the wires and see how i go for a while and look at changing it to this http://www.nengun.com/apexi/avc-r (499-X002) $79 + deliv.

ok.....so now i'm trying to work out which wires on the map sensor correspond to the wires for my gauge.

anybody know what each of the wires from the map sensor are?

white:

greenish blue:

red:

or anyone know if the wires that connect an apexi boost gauge to a MAP/boost sensor are different to:

red: power

black: ground?

white: signal?
