i need to know what connector goes where and which color they are....
like the bracket on the fire wall that has 6 (i think its 6 or 5 :-? ) colored connectors held in place i need to know which color is responsible for what connector... if i could get a picture of those connectors and maybe someone to label which one is which, that would be awesome! Thank You :-)
