Wireing diagram 1986 50hp Evinrude

[blink]

i have a 1986 50hp Evinrude motor and i have a wireing diagram from Seloc on the control. i have figured out most of the items in the diagram but they dont label what the devices are on the diagram. i need to know what the Tan wire and the Grey wires are for. i think the tan is for a Tempeture light but i am not sure. Can someone help me with this.

Tan is temp alarm (grounding it sounds the alarm). Grey is tach sensor line. BTW, the third party manuals are not highly regarded here. OEM is the best book.

You will pay more for an OEM manual, but it's worth it, the Seloc manuals are a generalization at best, the other option is to go to the library and get a photocopy of an original diagram if you can find it, then tuck it away in a safe place for future reference.
