I finally got round to testing my buttons.....
I have hooked up the copper momentary button to the brake switch signal wires. Took me a bit of time to work out how the feck the brake pedal switch worked. It has 4 wires, 2 are 12volt and 2 are earth, but the trick is when you install the pedal switch, you have to turn it to click it into the locked position. Now when its in the lock position there is a small tab on the pedal switch that engages the brake switch signal circuit.
So what happens when you push the brake pedal, the brake light circuit closes and the brake signal circuit opens - I think that's right, it might be the other way round.
So all I did was wire each terminal from the push button to the brake pedal signal wires, one to the 12v and one to the earth.
Now when I push the button and the throttle is past the required % = safe map switching on the fly.
No more dodgy left foot "braking"
Now to the FUN button...... as you can see in the above picture it says BOOST
and when its on, it LIGHTS UP
Now the fun button does 2 things.
No1 - It turns on the WMI
No2 - It turns "on" the N75
The fun button is a push on/off NO/NC button.
I have hooked it up to 2 relays. One relay is connected the 12v feed to the n75, so when the fun button is on the relay engages and completes the N75 circuit, giving the ECU control over the N75. When the fun button is off, n75 circuit is open and it runs wastegate pressure.
Its the same setup for the WMI system, but with different wiring for the relay
I used 5 pin relays as they are NO/NC and can be used to turn circuits off or on. So when the fun button is on, one circuit becomes closed and the other becomes closed. So I used the closed circuit to "activate" the relay and turn the WMI on. Again this took me awhile to work out and the hamster in my head was tired from keeping the wheel spinning for so long
