Has anyone added a tilt trim gauage to a 90's model Merc?

Did a bit more research
On the back of my dash there are several wires not hooked up.
I see a brown with white stripe, which must be the tilt sender.
There is a tan then a tan/w blue
The tan/w blue is tied in to the temp horn,

Also a few others I wondering about
A black/w yellow coming off the ignition switch it has a plug in snap plug end.
Then there is a purple jumper wire zip tied near the plug that goes to the tilt trim in the throttle.

you are right about what you found under the dash. The black and yellow wire would be the kill circuit for the safety lanyard. Not sure about the purple jumper. Purple is key switched power. What controller is it?

[CharlestonSC]

not sure what the control is, I'll have to check the little sticker on it.
so do would you say the plane tan wire is the sender for the temp?
and why did they tap in the temp horn to the tanw/white then ran it to the back of the tac with the plane tan wire, will I use both?

[captpete13]

the tan wire is temp. Not sure what all that is with your horn.

The controler is a Morse it could be 1989 that came with the boat or 1994 what the motor is. It has tilt trim in the handle.
Thanks for all your help

I found that trim guage. Its not a merc guage. I think its teleflex. It has a black face with white lettering. If you want it I will bring it down to Charleston with me on Thursday.
