I have been searching for hours trying to find a solution as to where to grab power from for a digital temp gauge. I see many guys using the blue wire or brake light on the bars but i would prefer using something closer to the gauge pod since I would like to mount mine there.

I'm not even 100% sure that it will operate on my sled since its a 99 and running ac power throughout? Any help would be appreciated.
 
it will work just fine, splice the power wire into the power wire for your gauge. ground it to the ground for the headlights. i don't know what color wires that is on your year, but im sure you can figure it out.
 
Does the stock temp sensor send info to the cdi unit on my sled to adjust timing and such? Or is it just to turn on the light when it gets hot?
 
Got it hooked up today to the fuel gauge power wire and the headlight ground and seems to be working great. I was originally going to put it where the stock sensor is but it turns out my fitting is not the right size. I just picked up an inline fitting like this. I will post back with results.
 
think I will go to Can Tire to get one.Where did you find the in line fitting???Let us know if it works.Will you have a backlight on it when riding at night??
 
what is the ID of the coolant hose by the way???How did you handle the wire to the gauge every time you open up the hood??Would like to see how it will look.Can you take some more pics to show us???Thanks!!
 
I got the inline fitting off of ebay for $20, just search for "water temp adapter". The hose is 1" id so you need the 26mm adapter with the 1/8" NPT thread. The gauge does have a backlight and looks similar to the stock gauges.

I will go and take some pics and post them up in a few mins of the wiring. It isn't finished yet but you will get the idea.

I spliced into the brown wire going to the tach for power:

Then I spliced into the headlight ground (black) for the ground:

Then the sensor wire will run down the hood beside the main wire harness:

i have a autometer on mine the same mounting place but i never hooked mine up cause i was told the sled doesnt reach a 100 degrees so it wont move. i was told to find a temp gauge that starts at 50 up to 150 at lease cause there is no thermosat but then again thats what someone told me ..let me know how u make out maybe ill run some wires o yea if u buy a kit from autometer u get all the fittings and temp switch that screws in
