I'd like to hide the ECU, and have been told NOT to mess with the length of the wires to the box. So if I buy the "updated" harness from Year One, where do the wires split off the harness to go to the ECU? Where will this allow me to hide it?

There are systems that install inside the distributor cap. If you still want to use the MP kit, there is a company that makes a bracket that will mount the ECU to the back of the passengers side cylinder head. You will still be able to see it but it isn't as obvious as one mounted on the firewall.

The heat and lack of air flow will cause that black goop in the ECU to melt off and drip down your block. I saw one that melted right in the engine bay on the firewall even with that factory dog-leg bracket. If they make a bracket for the cylinder head whats the harm in sending it another 3 inches and mounting it on the inside of the firewall and running your wires inside the fenderwell in a hardline so road debris doesnt get to it and then connect it where it has to go Family owned 1969 Charger R/T DualQuad 440/727/GVO/3.55s

I had a friend who's brand new harness was jacked up. Took forever to find the problem, never thought it could be a brand new harness.... Anyways, I take the supplied harness in the MP kits and extend them to reach the ballast resistor and (-) coil post. I then extend the distributor connector/harness to as well, reach the coil. Once I have the desired lengths, I wrap the harness with black electrical tape neatly to give that OEM look. I used the supplied spades in the kit and utilized terminal cover on the ballast resistor connection. I place a "t" at the appropriate ballast resistor terminal and reconnect the blue OEM wire and then the distributor harness spade. I have the power I need but the flexibility to remove the complete harness if need be. Plus, you don't have to compromise the original engine harness. It looks neat, factory and can be easily removed..

As far as mounting it to the head...the OP was asking for suggestions. I remembered seeing that bracket so I mentioned it. Don't know if there are problems with heat or not.

When I bought the new engine harness, they modified it to extend the harness from where the horns are , down underneath the front rail and up again behind the headlight. Been there four years now, I've had no issues. Gets lots of air at that location. See pic 5812384-DSC00829.JPG (80 downloads)

I would have gone with a Pertronix Ignitior II and hid the Mopar ECU, esp if it's the orange box, in the trash because that's where you'll be throwing them

This way no holes are drilled in the body, (only in the battery tray), it is in a place that is nice and cool, and fairly well protected. It is also totally invisible. Lengthening the wires is not a problem at all, in fact it was stated in the instructions that came with my kit. I had zero problems with this, has been on the car for 10 years.
