6.4 engine controller options

I am pretty sure that MMX gets the ECU from Hotwire and the harness. My harness came from Hotwire and I went to junkyard and got 05 ECU for my 5.7 for $75. Call Hotwire and see what they say as far as options. They are very helpful. I am pretty sure you will have to have sending units for your particular guages. It’s all gonna cost $$$. Seems a lot of people have had good luck with mega squirt on their swaps. A friend just did the Mopar performance ECU and harness with good comments 6.4 w727. My harness has fuel, alt, ac compressor
