Well I worked the harness on the truck myself. I removed all the things that I didnt need from the stock harness and labeled and kept everything that I did. Used the nbs fuse block for ease of install. Although if I were to do it again I would take a few more hours and just make a standalone harness to clean up the engine bay a bit. I guess I should of gave a little more info about the truck thats my fault. All of my spare time and patience has went in the truck so it makes it easy to get a bit lazy in other areas.(Havent done my laundry in weeks lol). I'll try to post a pic of what I did to the oil pressure sensor. I don't know if every brand sensor's case will pop off but this one did no problem. I figured out the problem by unplugging the plug to the oil pressure sensor and the pump turned off right away. Also noticed if i wiggled the plug on the sensor that the pump would come on and off which was a dead giveaway that it was something wrong inside of the sensor. Pressure read fine on the gauge, but the contacts inside were an issue.
