[Fired Up]

I run a boat with a drag boat racing organization. I was using a pair of digiset timers to activate the NOS systems with a micro switch at WOT on the carb. We added a new MSD GRID ignition and controller. We’d like to use the Output lead (brown/white wire) to activate the relay and eliminate the digisets. Does this wiring schematic look correct?

Is there a reason why you don't do it like we do, with a WOT on the launch instead of a timer??
I love watching you guys and have no clue what it takes to run one of those monsters!!!

That’s precisely how we do it. Still need a timer for duration of the shot. Just wanted to be sure the GRID is placed correctly on my schematic

If you use a WOT why do you need a timer, when you finish your pass, you lift, the nitrous is off.
Flip the toggle and drive back like everyone else does.

Why not KISS and eliminate an unnecessary circuit???
