Anyone use this?

You can still make it look Mopar by getting an old Mopar 5 pin ECU & gutting it. MSD module will fit inside. Piggy back the MSD onto a piece of 1/8" -3/16" alum plate, the same size or slightly larger than the existing heat sink; use the supplied white heat sink paste between the two.
The original ECU just becomes a cover; you can connect the module wires to the existing ECU socket & use the existing harness, BUT it will have to be wired slightly differently. ECU cover does not need removing to set/change rev limiter, it is done by grounding a wire.
The module needs to be grounded & this is done with the two screws that pass through the heat sink; should be nut & screw, clean metal, star washer for secure ground. The ECU cover no longer needs to be grounded & can be secured with sheet metal screws. Use an E core like a MSD #8207 & you will have a powerful ign system & can run 0.060" gaps.
If anybody is interested, I can provide more detail on the wiring process.
