What Color wire?

89 pickup 4.9 Oil pressure sensor wire color? Anyone?

I cannot find a good engine bay wiring diagram. I've googled and Bing'd my *** off. My wiring is butchered by a moron, I need to locate the proper color out of the loom so I can run a new lead.

The Temp Sensor wire is white with a red stripe maybe? If you know that answer, please hook me up also.

Thanks folks,

Koolminx

Oh God you are so awesome I do have the oil pressure switch wire. I just have it off to the side where I was stashing stuff while installing the engine!

I know my oil pressure is good before the break in. I took a measurement while I was priming the system. This is with my drill set at 500-550 rpm. So that’s basically 1100 rpm of the crank.

I will now set to making my temperature sensor work in the dash as well as the oil pressure. I am almost there with a full functioning vehicle lol dealing with the fuel tank selector valve today and testing fuel flow from each tank. Probably have to spend another 300 bucks on fuel pumps and a selector switch but at least I know everything will be new by the time I’m done

I would upgrade to a newer design fuel switching before I bought that reservoir
