wiring issue number 1

sounds crazy but i guess thats whats going on. maybe im just not thinking outside the box. it sucks that im not home right now. Im gonna try to explain this as easy as i can. Suppose i have ignition part of the harness plugged in. Ok, since i know that it will match the groove placement for wiper/nss side, if i turn the bulkhead for the light part of the harness the other way, will the grooves match to drivers side bulkhead on the firewall? and thanks for the picture
