wire identification 86gt seriously

two round or oval plugs one has 7 wires and one has 4 located neer the wiper motor upper right hand corner under the hood that attach the dash harness were old and corroded so i replaced them and the rest of the engine or ecm harness but they are different colors although both from an 86 5.0 mines gt maybe thats the difference but anyway i couldnt match up one of the wires on one of the dash connectors its orange with a blue stripe...ideally i would like to look at a schematic of those two connectors and identification of what they do or what theyre for at least the orange blue one.. ANYONE???
Even where i could find the info maybe website with good schematics
