What wires go where and do I need a ballast resistor ? I am hooking it up to a big block 460 in my boat. I sent an email to tech support and havent heard back yet and I NEED to get this project done ASAP. I dont have the directions for the 6A, it is a used piece from a friend. Thanks for any diagrams or help you can throw my way !!

For an automotive engine hookup, the 6A should be attached as follows.

Red 18ga. wire - To switched 12 volts, ignition key wire.
Orange 18ga wire - To coil positive (+). Note: no other wires should be connected to coil (+).
Black 18ga wire - To coil negative (-). Note: no other wires should be connected to coil (-).
If triggering through a factory ignition or points.
White 18ga wire - To wire that was originally connected to coil negative terminal. Wire from the ignition amplifier or distributor points.
If triggering directly from a magnetic pickup distributor.
Violet 18ga wire - To magnetic pickup positive wire.
Green 18ga wire - To magnetic pickup negative wire.

Red 12ga wire - To battery positive (+).
Black 12 ga wire - To battery negative (-)

Please note that the MSD 6A is not intended for marine applications. The correct unit for that application is the MSD 6M Ignition, PN 6460. The MSD 6M is U.L. certified to meet or exceed all US Coast Guard safety requirements for marine use.
