Default 1993 Si (d15z1 block) Check engine 15 & 48

Hey guys this is my first time posting here and this is my first car I picked up a 1993 Honda Civic SI little did I know what actually shape the car was in and what I up against. A couple different people have told me different things about it saying its horrible to its not to bad I figured id let all of you gurus take a look and see what you think.

Ive been told my catalytic converter is in the wrong place and from a gsr.(The whole exhaust maybe?) and would this be the fix to the code 15?

Next is the wiring harness this is what i am lead to beileve is the problem for the code 48 idk anything about this stuff but i have a 5 wire o2 sensor

image:



and the 5 wire to 7 wires leads to a whole jumbled up mess up plugs

I know the information i gave may have been limitied but if you guys need anything from me im willing to work, this is just my first car and wanna get it into a good running state.

Hey zigerog,

First off, welcome to H-T. I'm not familiar with your motor, but try posting it in the Civic section and I'm almost positive that someone will chime in on your questions. Good luck.

put in spacer between the o2 sensor and the manifold.
