I'm Awesome
Fellow GM truck enthusiasts,
Some time ago I made a thread dubbed “502 Accel 3500” with a different username. I was handed down a truck that was turned down by various garages/mechanics where I live. The harness was damaged severely due to a fire/excessive heat. I thought the air-intake was a twin root supercharger and the ‘502’ valve head covers had me fooled thinking I had a crate-engine. Since then I’ve learned a lot about automotive engineering and have decided that I want to study mechanical engineering. In an attempt to get this beauty back on the road, I’ve taken out the engine so that I can fully revamp the harness. Where necessary. I’ll be making a build thread as well but from what I’ve understood build threads do not allow for replies?
I was hoping to get some help with my engine rebuild and wiring questions.
The oil pressure/ temp sensor on the driver’s side of the block (7.4L / 454 Gen V) has three wires coming out of it, the center one is still in the connector the other two are missing. I’m about to put two new wires on the connector but I need to know if they go to the ECU or to the gauges. I’ll attach photos below.
Additionally I’d like to ask about these mysterious holes in the engine heads, I think they’ve been made to allow coolant to pass because the intended holes were blocked the gasket.
