    Default stick car need help with nitrous activation please

    I have a new 7720 and 7730 I am installing in my car this week. It has a single stage of nitrous on it now also, I currently have a wot switch on it that is wired in thru a 12v on off switch, also have a clutch switch that is in the car that I have not used yet. lenco car so once clutch is up it stays there. how do I wire it so I can put it on the wood to launch the car and not be dumping no2 in it while waiting on the tree, I made one pass on my old system which was a 7al2 with a 2 step, I just didn't hold her on the limiter that pass.I have searched thru a lot of drawings here but haven't seen one that I feel is like mine. Great forum :thumbup1:

    still need help, got all the relays wired up just need to know if the clutch switch needs to be grounded with the clutch engaged or grounded with the clutch released... also screen shot for set up using the violet or step 2 wire to turn spray on
