Trim/tilt sensor for a '89' Force 85hp outboard?

[AFFTAXI]

I am looking to add a trim/tilt sensor to my pontoon with a '89' Force 85hp engine. I already have a gauge in the dash but there is no sensor on the motor. Any ideas on where I could find one?

Try using the search function??
I've seen something on here a long time ago.
But I can't remember what was done.
