So hooking up the remote controls was pretty easy, I do need to hook up the rest of the harness to the boat harness for tach, etc.
I have a diagram of the remote, it says what color the wires are, but not what those wires do? I found a website that seems to have some kind of explanation of what the wires are, but it's a little confusing. The only thing I need help with is what's called the tachometer/accessories harness connector. This is what that looks like.

My other remote had a harness that came off of it that had a red wire, purple wire for the tach, orange wire for the warning horn, and a ground wire.
This one has, as you can see, a black, grey, purple wire connected to the molex, and a tan and brown/white wire. I'm assuming the black is ground. I did some voltage tests with key off/on; I did not do these with the motor running. I get about 2.5 to 3v on the purple with the key off, 12.6v (which is what the battery reads) with the key on. The grey wire gives off 11.97v no matter whether the key is on or off. I tested the other two wires, got 7.5v on one, and right at 12v, on the other, but I can't remember which one was which and if the key was on or off. I'm thinking it was on. On the diagram I've got, it seems that the warning horn is installed inside the control box? On my other control, this wasn't the case.
So...Is purple 12v positive? If it is, then why do I still get voltage with the key off? Is the grey tachometer? It looks like the solid tan is for a temp gauge, and the brown/white for a trim indicator? There's also another wire by itself next to the plug, that also looks tan.
Can anyone help out?
