Source for PCM wire harness connectors

I'm adding some after-market equipment to a 2007 police interceptor that requires cutting and tapping some wires going to the Power Control Module. I would rather not cut wires on the factory PCM wire harness.

I thought I would buy or build a wire harness extension. Does anyone have a suggestion on a source for the 70 pin PCM connectors? I've looked online and haven't been able to come up with anything.

The part number on the PCM connector is 5L3T-14A464-DA-041

Thanks.

Instead of cutting the wires, just strip the coating back so the wires can make good contact. That way the original wiring maintains its integrity and if you remove the add-ons, the wiring will not be harmed.
