Hey all,

Looked through all the threads and no one has commented on where best/easiest to hook the third wire that runs out of the MSD with the 12V +ve and -ve lines. Apparently you're supposed to attach it to a line that only sees power when the key is turned.

Where does everyone else put it?

 

I think I hooked it up the positive wire of one of the coils. That's only on when you turn the key.

 

i tapped mine into the stock power wire on the ignitor, and ran the white wire to the neg of the leading ignitor (removing the stock neg wire)
