Hello everyone im miguel
I need your Help i recently got a nitrous kit installed by a shop , they did a terrible job absolutely terrible one you can call worse than a non performance shop worse than even a common individual would do soooo as usual i had to tear it down and install it myself the right way
I always do things on my own but i had no time and figured well a shop can do it.... anyways

Its a zex single nozzle wet kit
Zex bottle heater
Nitrous express opener
Zex purge kit
BMN window switch
Nos bottle gauge
Zex blowdown tube
Zex bottle blanket

With jets for 55-125 shots


I have wired and plumbed everything
I have a 3 relay harness i rigged up

question is

I need signal to the white wire on zex box that should go to tps
Signal

I have found that connector c3 pin 21 has a yellow wire that should be tps signal but it puts out 68v? How i have no idea

Im looking towards a 0-5v signal
And the wire i tapped on the pedal gives me .224v not pressing the pedal
And .49v at full open throttle
This has me confused completely.


The second and last wire i need to complete my install is the white wire of the BMN window switch which should go to RPM signal

Now the switch suggests i tap onto the negative side of a coil
And what ive found is the rpm signal comes off the c3 pin2 pink or pink with black wire

But the wire on pin 2 is or looks to me like a black with brown stripe wire which has me out of my game

If anyone can help id appreciate it
