Nitrous plumbing A1A...??..

One more thing i just thought about.

The button on my shifter has very small gauge wire in and out. Im probably pushing the limit of that wire j8st runningy two step and line lock on that small gauge.

I know the line lock pulls so.e serious amps and i bet those solenoids are pulling amps.

You may think about buying a cheep relay from the local parts store and just using the small wire from the button to open and close the relay. Then run all the high amp draw stuff off the relay?

Just a thought.
