good afternoon evryone. i am here seeking help
i have a project car that i completely send to do a rust free restoration.
i remove the entire interior & exterior a simple body nothing in or out 2 years ago.
i am alomost to the point of installing the engine but i wanted to finish all the electrical installatiion.
long short story here is the problem. i recognize a 1990 harneses not interchangeble with an lx quite a few diferences
so i sued all my harness from my lx. coomputer harnes, main harness, and tail light harness same as dors and all that the only one i am using from the 1990 is the head lights.
hig and low beam work fine
signals just fine
break lights just fine
interior no light
cluster no lights on the rear and front there is the small lights that when you turn with out headlights they are suposed to come on but they dont front or back.
i check the fuses, bulbs, dimer for the iner lights. not even the center console lights come on.
now after i conect all harneses i came across a few conections that did not match to conect to anything maybe a relay missing idk.
does anyone have an exploded diagram on the harneses for the 1989 for mustang LX.engine and behind dash

 

 

This is for a 90 routing of the wire harnesses are identical to the 89 with the exception of the crash sensor wiring
