theres 3wires coming off the module. 1 plug that goes into the msd box,1 ground and 1 power wire . how i use to have it was, i grounded the ground wire and had the power wire to a switched 12volt button....my question is, can i wire the red wire to a constant 12+ and hook up the ground wire to a switch ground like a horn button or a e-brake?........ will the 2step work will a switch ground or it has to be a switch 12volt?

 

here is how we have ours - LineLoc on rear brakes - pushbutton switch on shift **** - it works slick - push clutch & brake pedals in & hit button on shift **** - locks rear brakes to keep it from rolling - bring engine up on rev limiter - release clutch and it releases the brakes and shuts off launch rev limit



here is shift **** we used:

the way you have it wired up is still using a switch 12+. what i wanna know is, can i use a switch ground. just the oppostie of how you have the power and ground. am i explaining myself rite?

 

of course it will!! just make your switch on the ground side and thats it.. vice versa the layout he made on the clutch switch

 

just called MSD and talked to one of the tech's and he said "you have to use a 12+ power to active it. you can't use a ground, cus when you kill the ground you'll brun the msd unit out". i thought the ground would work just like a power, but i guess not. I'll just stick with his advise and use a power to activate it.

 

what if you're only using it for a lauch control, were would the red wire go? the clutch switch/hand held button?

 

i'm using mine for staging, i'm wire it off the horn. the horn has two wires, 1 goes to 12+ and the other to the msd red power wire. thats it, sleeper
