How do I hook up my Tach to my MSD 6AL
I installed a MSD 6AL in my boat along with a pro billet MSD distributor and I am wondering how to hook up the tach to the MSD 6AL..? Where do I find the tach wire in the back of the boat..?
Thanks
Anthony

red and black harness from box to coil. orange and white harness from box to existing wires that WERE mounted to coil. orange to 2 purple wires off coil. white to 2 grey wires off coil. grey is mercury tach signal wire.
use quick disconnects, especially if your retaing stock merc module. this way when the box craps out on you , you can just return wiring to stock and get home.
