1993 Mustang 5.0 Conversion Fuel Pump Wiring Question

I am putting a 1993 5.0 Mustang engine in my Bronco. The green connector on the stock Mustang harness by the EEC has two dark green and yellow wires for fuel pump power and fuel pump monitor.

Do I need to run the fuel pump monitor? Is this another relay I need to add?

More important, do I need to run a relay for the fuel pump power or is it already in the harness and I run this directly to the pump?

There is also a gray/yellow wire for hego power. Do I need to run a relay for this or connect is straight to power?

Thanks in advance. I attached a picture of the connector

yes you need FPM

Yes you need a relay for the fuel pump
yes run a relay for HEGO power

go to the RJM site he give you a good guide on power distribution.

I usually get rid of the green plug and redo the wires to my liking..
