Reconfigure Engine Control Unit Connectors

Hi there,
If you want to completely reconfigure the connectors for the engine control unit, where can you get suitable tools and parts?

I would take the fully wired connector from a scrapped vehicle.
To rework it, you would first need a good tool for removing the pins.
Then you'll definitely need new crimp connectors and a suitable crimping tool.
I would also take the appropriate cables from an old wiring harness; there should be plenty available there.

Where can I find wire stripping tools, connectors, and a crimping tool?

The MSG would be an EDC 15.
