Hey Chuck, thanks for reaching out!
I recommend going with the Curt T-Connector Vehicle Wiring Harness # C24ZV for your 2025 Mazda CX-70 because it's a simple Tee-in installation so it's much more simple than getting in behind your tail lights and splicing into your OEM wiring.
If you then wanted to add a 5-Way you would need the Kit # 20036 which requires you to splice that blue wire into your reverse light function.
Attached is an installation video for your reference!
