    Default Wiring help -MSD ignition and nitrous

    I am looking for a wiring diagram for MSD 7AL-3. I have a transbrake WOT switch, two ford style continous relays, two stages of nitrous, and two test buttons for nitrous. I would like first stage to come on when transbrake is released. Second stage on when shifts into second gear. I also have a crank trigger. Please help.

    part number on "ford " solenoids...( have nos brand purge 2 nos super pro shot foggers ) and the nos parts also , to come on in second gear , you will either need a timer or a micro switch on the shifter for a gear indicator for a
    relay or timer.

    if you were using, lets say the powergrid ....or 7531 ...then we could of done the gear change off of that . the 7al-3 unfortunately does not have that feature ..

    but no, problem....
