Mercury Trim Wiring - new control box

[zracer]

I have a 1986 XR2 with power trim. The control box broke and I am replacing it with the new style box. My question is on trim/tilt wiring. Here is what I have;

New Box:
Blue/White
Green/White
Tan
Brown/White

Motor:
Blue/White - up
Green/White- down
Red- fused power
Black/white- goes to trim sensor

Where does the brown/white and tan go?

Also,
My warning horn is also not beeping when I power on the key? The new control box has a built in warning horn, the old box had an external. The warning horn was working with the old box.
Everything else appears to be working.

Tan is the warning horn. Ground it and the horn goes off. Usually it is connected to the overheat sensor and the oil warning module. The warning module is the part that gives the startup test beep.
