theirs the black white and blue wire from the TPS, which one do i need to "T" into to make the zex nitrous box function at WOT. i tested with a volt meter and got the changing voltage on the black wire, but when its hooked up, the nitrous doesnt work at WOT. so it must be a blue or white wire, i figured black was gruond anyways,

Use the Dark Blue
Black is the ground

Your will get voltage on the black b/c yiour have to ground the 5v to creat a complete circuit.

Blue to black. WOT=4.5v+
Black to blue. WOT=4.5-

And i think the white is the varying voltage signal back to the ecm.

The ECM supplies a 5 volt reference voltage at the grey wire.
