Mark:

A few questions first to make sure which specific model we are dealing with, please answer all:

1)Is your 750 an "F" version?(mixed oil and fuel, instead of separate oil tank)

2)Your current compressor spinner nut, is it conical or flat?

3)If conical, does it have a cross through hole on the tip or does it have an hexagonal base?

4)Do you plan to keep the current front cover and Jetjoe starter?

I already told Carlos on a PM where he can get the ECU, it includes Remote Display, all cabling, glow plug harness, RPM sensor and a Thermocouple, I would rather use the thermocouple you already have as the one included is rather short for a 750, I believe RAM uses ungrounded thermocouples, that's the type you need, you just have to check to confirm before using it. You need to also get the two solenoid valves for gas and fuel.

Once you provide the answers to the questions above I will tell you step by step what you need to do
