wiring harness

I' m looking for what I think may be the ECM wiring harness. It is a round plug at the firewall and goes to three different plugs. It is on the drivers side above the wheel well. Mine was taken out by mice.
The vehicle is a 1989 Ford F-150 with a 4.9L 6 cylinder engine and a 5 speed standard transmission

Any help is appreciated
