thanks I'll check it out. I am redoing my dash and I want to add a trim gauge and temp gauge, from what I have read I can just tap off the wire going to the temp horn in the dash, do you know?

takes a different sender for temp, the alarm is an on/off type sender(actually a switch), where as a temp gauge sender is a variable resistance sender to actuate the gauge. I personally don't worry about a temp gauge, I'd use a tach, fual gauge, volt gauge and a water pressure gauge if it were mine(thats what I intend to put in my boat), make sure your temp alarm is working

on your motor one of the temp switches also is a sender. I think it is in the port head. Check the cylinder heads. between the spark plugs there will be a sensor with wires comming out of it. there is one on each head. The one with one wire(tan/blue) is the overheat switch. The sensor with a few wires(tan,tan/blue,black)is the temp sender. There should be a connector for it by your main engine harness.

Ok this is what I see, on the left side looking at the back of the engine is a solid tan wire that hooks to the harnes plug that goes to the gauges. right side is the tan with blue stripe that goes to a terminal block then goes in to the wraped motor wires looks like it changes into a blue with black stripe
So is it the solid tan wire that is the sending temp wire? You guys are awsom thats for all the input.

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?

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?
