Thank you Ernest for a quick reply,
The ECU and harness are quite expensive, I was trying to explore other options. It seems that someone was able to swap engine from 2007 FX HO to his 2005 FX HO:
MY main concern is the dashboard,as it is completely dead.
I was hoping to get some fault codes on it.
What should I start checking, to see why the dashboard is not operational?
Could it be bad rectifier?
On the connector I can see that the dielectric grease is light green as it's mixed with copper oxide.
