Ok i am putting nitrous on my LT1, i finally need to use the retard feature on my digital 6.. Only problem is that i have lost the instructions and can't remember if you send the box a ground signal or a hot signal... any help would be great....

 

You would hook-up the pink wire to a positive signal.

Here's the instructions for the Digital 6: http://www.msdignition.com/pdf/MSD_Digital_6.pdf
