HELP Nitrous Express controller wiring
So I connected to the PURPLE WIRE line was suggested on the TB connection and this popped up.
I then connected to the green wire coming off the TB and got the same error code but without the bars after "error tps"
Can anyone help me out on what I'm doing wrong?
All wires look good an reconnected all connections.
Please post on here or contact me

The green wire is the one you should be using. With a Nos Mini I was having issues with the purple wire, swapped to the green, and didn't have issues anymore. I'm not familiar with the NX controller, but the green wire signal is reverse of the purple wire maybe a setting on the controller that needs to be changed?
Also double-check any grounds, electronics do weird stuff with bad grounds sometimes.

Cause a lot of people will blow the welds on their intake manifolds and drop their floor pans. Then me and the mad scientist will have to rip apart the block, and replace the piston rings they fried.
