Hi,
Do you have any nice pictures with engine wiring harness schematic? I mean everything with coil, injectors, all sensors etc. It is a 1989 302 5.0 efi unit.

I am attaching all these diagrams. It appears all sensors are on these two systems (fuel and ignition) so it should have everything you need.

Here are a couple guides that can help when doing these types of repairs:

Please run through this and let us know what other info you need.

Thanks
