1975 fiberform Tilt/Trim question

[Rip n Lips]

I have a older boat with a 115 merc. The Wiring harness for my tilt/trim came unplugged. After a struggle I finally got the rubber boot at the end with the 3 male adapters plugged in and the tilt down now works. Unfortunatley there is 2 wires that branch out before that plug that go to my tilt/trim up switch. They have female adapter ends on them and I don't know where they go to. I was told that they go to the Trim Limit Switch but looking around I can't find where that is? Can anyone explain to me where that limit switch is or possibly have a wiring diagram I can look at? Thank You.
