Steering column connector

70 Duster, so key is on the column. I have not done the mad rewire but have taken the bulkhead connector apart, cleaned all terminals and replaced any bad ones. Same with most of the under hood and behind dash wiring. I have Crackbacks headlight relay setup, everything else is stock. Redfish is correct on the connector, flat white one with ignition connections.

I am putting in a Holley sniper. Fuel pump is off a relay. What I need to do is tap into the brown and dark blue wires for the Sniper ecu. Supposed to be less than 3 amps. Hooking up at the steering column is convenient as I am putting in a inertial switch under the dash in case of an accident, I can also use it as a anti theft devise to cut all power to fuel pump and EFI. Instead of just cutting and splicing wires I want to connect at the connector pins, just seems like a cleaner install to me. I ran into something like this before. Would like to just repin the existing connector if I can, but am wondering if it would just easier to update to a newer style connector if I can find one that works.
