1989 Ford Ranger XLT 4wd swapped from 2.9 to 4.0

When I bought this truck there was some wires torn and eaten on the passenger side floor board. I figured that I can get another inertia switch and rewire it to the original harness. The thing is I don't have a clue what it's going to and how to remove whatever it is, so I can rewire it. I've got the part of the harness that clips in but it's more than just the wires on the inertia switch itself. I know that it's below the blower motor

Inertia switch should just have 2 terminals, its just an IN/OUT switch

In 1989 it should just have 2 wires, one on each terminal
A dark green/yellow stripe wire, IN from Fuel Pump Relay
A Pink/black stripe wire, OUT to fuel pump

There may be a 2nd dark green wire, monitors if Fuel Pump Relay is working, both greens are connected to same terminal

I've got the switch and it's only got the two wires but there more wires missing further through the firewall I don't know what it is below the blower
