(NEED HELP)-FD3S Fuel Pump/ Sender Wiring/ Color Code

First time post, long time viewer. I have a 3rd Gen 1992 Efini RX-7 FD and im rewiring the rear hatch include the fuel pump. I spliced the wires going into the tank and I believe there are 5 of them, of course different colors. Does anyone have any information on what these wires go to? Any help would be appreciated.

That's all going to be in the service manual's wiring diagrams.

I think the wires are going to be power/ground for the pump, in/out for the fuel level sender, and 1 wire for the low gas light.
