HELP!!

What are these and do i need them?

Bump so the topic doesn't get lost and unanswered.

Jeff, the black one is a MAP sensor. Manifold absolute preasure. I will go out side and figure out hte other 2 real quick. If you are keeping your engine stock you need the map sensor.

The longer metal one in the back of the 3 is the horn relay, you will probably want to keep that, however, you can easily relocate that one. If you can tell me what the colors of the wires are coming out of thew middle one I can look it up real quick on my schematic book, but I got rid of it when I did my motor swap, so I don't know off hand. Hopes that helps some -ED

It helped a ton and we will check on the wire color and get back to you. Thanks!!

Ok now what about the headlights do you have to ground them all to the same ground or can you ground at each light to the chassis? Thanks,

you can just ground them to the chassis where it is convenient
