One diagram shows under steering column and another show under passenger side dashboard but I can't find in either place
There is a main relay on the right kick panel

Although the Haynes repair manual did not have an electrical diagram for the horn circuit, I suddenly remembered I had an old CD-ROM based Auto Repair program from Popular Mechanics that has an extensive selection of diagrams. It did have a diagram for the horn circuit which showed that there was no horn relay in the circuit. So I started by taking apart the horn button on the steering wheel. The horn button is a switch consisting of two metal discs approximately two inches in diameter which are separated by a thin layer of foam which is supposed to keep the two discs separated. The metal discs have dimples that should be kept apart by the resiliency of the foam but when the foam is compacted, the dimples come together to complete the circuit. However, the foam had deteriorated to almost nothing and was allowing the two discs to be in constant contact. I solved the problem using picture hanging tape. This is a double-sided adhesive tape that is about 1/16 inch thick and comes in a roll and can be found probably anywhere hardware is sold. I cut the tape into small squares and stuck them to strategic points on the flat parts of one of the discs so that they would keep the discs apart with approximately the same resiliency as the foam. When external pressure is applied to the outer disc, the dimples come together just like before to complete the circuit and the horn works perfectly.
One thing I would like to point out is that when I initially took the horn apart, I started by removing the outer soft rubber cover from the horn pad to expose the horn button. It came off easily, but when it came time to put it back together, I could not get the cover back on. Then I discovered that there are three phillips head screws on the back side of the steering wheel that hold the horn button assembly in place. So to save time and frustration, I would recommend that step one be to remove those screws first.
SOURCE: how can i obtain the diagram for the fuse box located just underneath the steering column?
If you copy and paste this to your desktop you can zoom in on it.

Your vehicle's fuel pump relay is located on the relay center, behind the glove box, 2nd column of relays, 2nd one from the top.

did you check the lock mechanism under the wheel at the dash? you have to relock the wheel it sounds like by pushing the lock lever

the relay box should be under the hood on left or right side if not try behind glove box
