Is the fuel injection relay location for 77 and 78 is different? Also, is the ignition relay for 77 and 78 is different, too? Ans, 75 and 76 has a totally different relay locations for these two little guys? why did NISSAN make such a decision, not quiet user friendly because we need to dig up different wiring diagrams for different years, this cause a longer disgnostic time for the mechanics?????????
