MSD Window switch problem

So I installed a Nitrous outlet wet kit on my 05 CTS-V....I have the older style msd switch that uses the rpm pills. I have 3000 pill in the on and 6300 on the off. My issue is it wont spray until 6000 rpm? Does anyone know what my problem could be?

Do you have them backwards?

Or have you tried switching the two?

Kinda what I was thinkin somethins gotta be wired backwards or the pills are swapped Id triple check everything Usually people complain about the tach & spray cut off pill are like 200rpm off Thats mostly the factory tach off Sounds like things need checked again

I found my problem.....on the older MSD switch you have to cut 2 loops of wire and that puts it into 4 cylinder mode on the box(which is what is needed to read rpm on our cars)

This x2 forgot all about this I had the same problem this weekend my thumb hit the wrong button scrolling through the programming set-up and turned my car into a waste spark 4 cylinder car when it should of been coil on plug 4cylinder, our cars require the denotation 004 on any window switch to work.
