Trying to fix the reverse lights issue, we realized that my car was using an sr20 transmission cabling; therefore, I changed it for the original s13 cabling and guess what... not only the reverse lights still doesn't work but now the speedometer / milage gauge does not work.
My brother has tried every single cable combination, we have the s13 and s14 diagrams printed from all data software which is not telling us what changes between the at and mt trans cable positions and how to match them. It is really a pain because everything else is working so perfectly, I just don't know how fast I am going... not fair
I am going to take it an specialized electrician and see what I can find out; however, if you know anything or know somebody that can help, please let me know.
Thanks and I see you all 240 lovers in the street
Peace!
