Making a Q45 TB work on an S2 RB25DET

[streeteg]

Ok, so the most frustrating part of the build so far has been trying to find a TPS sensor for my car. I have an S2 RB25det which was bone stock from the get go with the exception of exhaust that I am not in the process of upgrading with minor bolt ons before the winter. As I did the Greddy Intake manifold, I replaced the throttle body with a Q45 unit that has been the most annoying thing on the planet trying to get to work.

Heres why:

So long story short none of them fit and I have no idea how to hardwire it or which one to use if I were to hardwire it.

(Q45 TPS) to harness

(Red) to yellow/black(white) to red/blue(black) to black/blue

Just splice and be done wit it. IF you want set the key to on and verify 5 volts at yellow/black wire.

YOU ARE THE MAN. GOD I searched for years for that ****. Thank you.

yeah - eh? is the man.

alright, So I read 5 volts on both red and white wires. I've grounded the signal wire somewhere I'm guessing. It's throwing my PFC for a loop, it shuts down every time I rev past half throttle. Anyone else had something like this happen. I'm gonna trace the wires tonight, if I can to see where I might have blundered...

is it suspose to be .45volt to .5 volt??? eh?

[eh?]

yes .4v to .5v

With the series 2, they have 2 plugs, how is the second plug wired up?

you don;t need to worry about that plug. it goes to one of the big white plugs near the ecu that aren't used.
