I pulled my washer bottle a long time ago and I remember I could not do much with the connectors since they are way up at the top. Maybe if you disconnect the connectors than you can pull the main harness down.
Now I did some rewiring in the headlight area and I think I was able to disconnect the connector for the front harness (headlights and blinkers) from that hole under the light bucket. But I'm not sure if you could get the other connectors that way.
