The vehicle did not come with one, but I got one from salvage because i'm told that it's an easy add. I even have the whole harness. Problem is I don't know where to connect it. Your expertise is much appreciated. If you can include pictures in your reply, that would be fantastic.
Do you

Hello,

I am not sure what all that stuff up there is, but this shouldn't be that hard to do. I am going to tell you how to do it, not like it would come from the factory like, but both should be unnoticable and work exactly the same. You will need a drill, wire stripper/crimper tool, and a wrench for the lock nut on the switch. Okay, here we go. Always disconnect the negative(-) battery cable when doing work on your vehicle.

1) Find a place on the edge of your hood that you can place a switch flush so that the plunger will be the only thing sticking up. You want it so that when the hood is closed the plunger will be flush. Keep in mind you are going to have the switch body and two female spade connectored wires coming in as well.

2) Go to the parts house or hardware store and get a plunger type switch, similar to what your vehicle uses for opening and closing doors in the front of the door jam, female spade connectors to fit the pins on the switch, butt connectors, enough wire to run to the underdash fuse box, ring connectors, toothed washers, self tapping screw, and a fuse tap.

3) Now that you have your location picked out drill a hole big enough the the sleeve of the switch will fit up through. Install the switch, using washers underneath to shim as necessary, so that just enough is sticking out of the whole to get your lock nut on and secure the switch. Tighten the lock nut.

4) Go to the underdash fuse box. It is located on the drivers side of the dashboard. Find a circuit that is "hot at all times". Fuse 18 should work. Pull out the fuse. Take your fuse tap and splice enough wire to to it, using a butt connector, that it will reach the switch you just installed in the engine compartment. Usually you find a grommet in the fire wall where wires are running through it, utilize this to route the wire. Install the fuse tap in fuse 18 slot. Install fuse 18 in the fuse tap.

5) On the other end of the wire from the fuse tap, crimp a female spade connector. Attach the wire to 1 pin of the switch.

6) Cut more wire long enough to run it to the light from the switch. Put a female spade connector on one end. Attach this end to the other pin of the switch. Route this wire out of the way of everything. You can install wire look, friction tape, and anchor it with zip ties for a professional look. Route it to the light. Attach it it one pine of the light. Run a wire from the other pin and crimp on the end of the wire a ring connector.

7) In a clean dry spot attach the ring connector to the vehicle body with a toothed washer underneath the ring connector. The toothed washer should chew through the paint and ensure a good metal to metal connection.

8) Put the negative(-) cable back on. And that's it. Now you should have a hood light come on every time you open your hood.

I have included the location and diagram for your vehicle's under dash fuse panel in the diagrams down below. Please let us know how it turns out and if we can help you with anything else.

Thanks,
Alex

Hello again,

Sorry about that. I was having a rash of this earlier, but I got it corrected. It was at my end. Here are the under hood fuse/relay block diagrams for your vehicle as promised earlier. Please get back to us with what you are able to find out.

Thanks,
Alex
