Any good wiring diagrams out there for 1990 Ford f150 4.9 that's shows the complete harness to the 3 connectors on top of the driver's side fender tub? I need the distributor/coil power, tach wire, engine temp, oil pressure, and battery voltage. Any help or references would be appreciated. It's a v8 swap conversion. Any my manuals don't show connector end view

Here is one that shows all of the connector pinouts:

That one looks good! on pro demand cus I remembered work bought it for me lol. But I'm.still not seeing any engine harness connectors labeled but I can trace wires. The 3 connectors on the driver's fender tub are the engine harness right? I'm probably gonna end up doing that and making a connector pin out for em. Here what I found 1990 f150 4.9 engine diagram

 

I have know idea what you are calling "The 3 connectors on the driver's fender tub".
Maybe a photo and the wire colors of the three will ID them. If I knew the three connectors you are talking about I would post a piout of them for you.
I see no connector pinouts in the image you posted above. Only pin numbers but not the detail of the connectors.

The item on ebay I posted above has every pinout on the 1990 F-series truck.
I have that same 1990 wiring diagram that I posted above.
I also have the 1990 EVTM wiring manual but it does not give many pinouts.
