    It can be done.First, you need to keep the Ford ECU happy, so you will need four MSD 8912 dual tach adapters, so the ECU thinks it's still driving the coils.The 8912 has outputs that normally trigger an MSD DIS-IV multi-channel CDI. Instead, you will need to invert each of the eight output signals to drive the LS2 coils.The inverters for each channel can be built with a couple of resistors and a small NPN transistor, such as PN2222.The collector of each transistor would connect to the LS2 coil trigger wire. It would also go to 12v through a 1k ohm resistor.The base of the transistor would connect to one of the tach adapter outputs, through a 10k resistor.The tach adapter outputs also need to be connected to 12v, through a 1k resistor.So, you have eight 1k resistors to 12v, one on each tach adapter output; eight more 1k resistors connected to 12v on each inverter output; and eight more 10k resistors, one to each transistor base.This comes from another post

    Thanks Mike , That's a lot knowledge !
    Something ill look into for sure.

    When switching to a stand alone do you have to run the LS coils? Is there a reason that stock 2V Mod Ford coils wouldn't work with a stand alone?

    I think the stock ford coils will work with select few standalone units how ever no one runs the stock units as the LS coils are way more powerful.

    Hate to bring these old posts back from the dead, but does anyone have any new pictures (most of the ones I've found are dead links). Looking for pictures of folks running the LS2 Truck coils (Round coils) with the built in ignitor and head sink. I have a set of Powergrid plates for mounting on top of the valve covers, but I'll have to modify them to run these coils.
