2.9 simplified/standalone harness

[Kentuckian93]

Does anyone have a schematic or write up of simplifying a stock 2.9 harness? Not finding much information in the forums, any help is greatly appreciated. Thanks
Edit: This is for off road use.

just power it up through the red/green stripe on the noise filter for on/off. make sure all of the grounds are hooked up and keep the fuel power intact.

Thanks for the reply Bobby, I should have said in my post it’s an 86. Red with green tracer powers what exactly? The engine bay is a complete rat’s nest between a previous owner splicing and rodents. Trying to eliminate any unnecessary wiring, headlights, horn ect. just what is needed to run the engine.
