I don't know I'm just going by the pictures on the Hyundai site. It does supply 12v to the fuel injectors, cam sensor and ECU.

So it will have a 12V Cut off point.



I do have a orange Cable that supplys 12V that i was left over when i removed the old engine loom. I wonder if that is what runs to that.

If i put my key in IGN and i get 12v from the wire and i remove the relay and it dies. im guessing i have the right thing ?

Well that's a clue. The only real way is to get to know the wire diagrams. You cannot always go by color but that is the first thing to look for. And you can judge the wire size you are looking for by seeing how big the fuse is. Bigger the fuse the bigger the wire.

the wire is the thicknessed cable iv seen inside the cab.



so im guessing thats what the coil and other sensors use ?

It looks like a 20A fusible link feeds both the fuel pump relay and the engine control relay so it would be a 12 ga wire I would guess. Then the fuel pump has no separate fuse? Also coming off that 20 A link is the ECU fuse #3 10A, and the engine control relay power which feeds ECU #1 fuse 10A

If you was me would you run my own wires and relays and forget the OEM stuff ? Idk whats easyest..i have no experince with wiring.

Red Raspberry

That's up to you but if you have no experience with doing wiring then doing something like this is questionable. If you do, you will sure know wring when you are done.
