So the engine harness had bare spots and was arking all over so ripped it out and re ran it all exactly like it was to the T and thought I took pics and marked plugs but I ended up with an extra and the only thing I’m noticing is the temp don’t show up on the gauge( the digital fancy shit) it just won’t move even as I cycle through the gauge button and can see the coolant temp is getting to temp (nothing over 220ish most times is a little lower than that) but will want to stall after about 20 minutes of driving or running if that even will start back up everytime but it seems like it’s trying to run in cold weather while it’s 90 degrees lol anyone know where I can find a diagram or anyone know if there’s 2 temp sensors or location on them ? At first the speed cluster didn’t work so I plug the first extra wire in to a plug on the passenger side back of the block and it works now just running funny and not accelerating like it should and help is greatly appreciated
