You change the engine wiring harness. So all the sensors, etc. That attach to the dme and engine.
The body harness stays the original ti. So nothing electrical really changes in the cab.
Depends on what is broke. If it's that ignition wire it is body harness and wouldn't be normally changed in an engine swap.
It doesn't look like fun to change, but wire is cheap. Just have to figure out which it is and where it goes. Maybe if you search "etm manual" here that might find a link to the schematics. |
