89 harness

[TN70C10]

i got a 89 harnes tbi dist ect ect out of a parts truck for my fuel injection swap over. im also using the 89 tilt wheel steering colum. i figure that the only thing thats going to give me a hard time is the headlights and wipers ,im using a vintage air kit . does anyone have any diagrams or can give me any info on what im going to have to swap to use my factory headlight switch with this harness? also want to use the wiper switch on 89 colum.
