6.1 hemi 6013 msd

You may find the Cam and Crank sensor on the motor are not compatible with the 6013 harness...depending on which MY the engine is and which harness you bought.

This is no big deal - you can either scavenge the plugs off a factory harness and splice them in - or - change the sensors to the correct type to suit the harness.

The only other "trick" I came across is I strongly suggest you locate the ECU inside the passenger cabin.....Its a lot of $$ to "cook" in the engine bay.

Last - if you run a factory tach - you may need the appropriate MSD tach adapter.
