six shooter wiring diagram

hi , i am istalling a 6 shooter 8158 and a timing retard box 8168 and i have a question about the 2 middle wires in the retard box( black and red ), are these wires the ones that supply power to the ret box?

 

any help? anyone is using these part no also please?

 

Google this -- MSD Six Shooter Module Selector
--------------------------------

I don't know if this will help, it shows a wiring diagram and states that --


Module Wires. This connector plugs directly into the retard module receptacle of the MSD Timing. Control.

 

thanks that helps me alot.
