ZEX Kit, need TPS Wire???

[xsohaib]

Hi all, I am in the middle of having the Zex kit installed, on the TPS what wire needs to be tapped to activate the system at WOT. So far we have tried most wires going into the TPS but in vain, either the NOS shoots all the time, or not at all somehow it isn't linking to the Throttle.. Where do I hook up the that wire from the Zex kit where it activates the system only at WOT.

Oh the car is a 92 ES300
Thanks in advance

It didn't come with a microswitch? I've only seen ones that come with this little switch that the wires lead to. Essentially, at full throttle, the throttle linkage bumps into the switch, giving the N2O the all clear to fire when activated.

nope the kit did not come with the microswitch! Is it supposed to come with the microswitch. I thought I was supposed to hook up the white wire to the tps wire reading the 6volts at WOT. and that, this should do the trick! the red wire to the 12volt constant and the black to ground.
Please clarify

Thanks

The TPS signal is a black wire and it is pin B-10 on the ecu. I used that for my safc-2 and that is the throttle signal, I forgot what the other wires do but get on aim and talk with toysrme257th if that wire wont work.

I checked with the voltmeter, and the wire that shows variability with throttle on the ES300 is the blue wire, or should I stll hook up to the black one. Also, how do I go about resetting the NMU?

Thanks
