1987 FORCE 125 trim sender installation

[mike0119]

I found an advice for this Mercury PRE-1995 820568A11995 trim gauge / sender kit‏ replacement parts on forums.iboats.com/showthread.php?t=148351.
I've already ordered the kit and am trying to figure out how to install it.
I just bough used trim/tilt assembly from 1987 Force 125 HP which I will use to retrofit my manual tilt 1985 Force 85 HP.
I know this much:
1/ sender unit should be mounted in the recess on the outside of the port clamp bracket
2/ the sender (potentiometer) shaft should protrude through the hole in the clamp bracket and should be indexed with the rotating arm on the inside of the bracket.
3/ the arm is supposed to turn as the swivel bracket moves up or down.....
I have tried all kinds of searches on Google to find details of this installation but to no avail...
Does anybody, by any chance, have drawings from service manual or photos showing how sender unit and rotating arm fit together and how are they suspended to clamp bracket and swivel bracket?
Any help or direction will be greatly appreciated.
THANKS AND GOD BLESS.
Mike

See if you can get your hands on a Clymers manual. barring revisions, the mounting diagram is in Chapter 11, page 400 illustration 15.

The sender goes outside the port clamp and the arm goes inside the port clamp with the spring loaded sender arm facing rearward. Two through bolts hold both halves of the assembly together and mounted. Two nuts hold the inside assembly onto the clamp and space the potentiometer. Thw washers go on top of these nuts, the potentiometer goes on over the protruding bolts and two more nuts hold on the potentiometer.

Raise and support the engine at the number 4 tilt hole position. remove the potentiometer and adjust until the gauge reads #4 position. Re install

Thanks Frank. I am getting a vague idea how this all fits together. It would apear as if there should be two through holes on the port clamp bracket for the two screws you are describing. Since there are none on my bracket I may have to drill those, except the new problem arises of proper location, spacing and sizing of the two mounting holes?
Another detail that is still not clear to me is where does the spring attach on swivel bracket so it can turn and move potentiometer shaft?
I do have SELOC Force Outboard Repair Manual but that book unfortunately does not address my concern. Adjusting procedure is described and clear.
I will try to get my hands on a Clymers manual, is this something that dealers would have or could it be found online?
I do appreciare prompt and detailed response.
