Voltage problems, cutting out when hot

Believe it or not I just ran to my storage unit and started thrashing through boxes and found this

It has some interesting extra instructions that come with it that simply do not match what is in the car now
The new switch has a single black wire where a orange wire should be and then two blank spaces where the original plug has two small gauge red wires running up to the switch. These are solid black and black w/yellow tracer going into the dash harness.
I’m assuming these extra wires are for the stupid seatbelt interlock system…
Once I get the old switch out I will compare and post pictures of what I find.

This is the new plug
