I recently got this, part number PN 6520. Link is here: http://www.msdignition.com/digi_1.htm

and I was wondering, I've re read all the isntall instructions. very basic. power wire, ground wire, then 4 wires taht wire onto your distributer, question is, how does just those 4 wires onto the distributer retard and advance the timing and alter rev limiters etc on my OBD0 1st Gen B16A motor?

 

they dont the pink wire on your digital 6 when you supply a 12volt to this wire like from the activation of nitrous selonoids it will retard timing
