I don't think the sensor you described will work. It is probably and "on/off" switch for the warning light. The guage sensor would have a variable output. Cuttin the hose isn't a big deal. I would just replace the stock sensor and wire with what comes in the kit. The stock sensor may or maynot be ompatible, but you would still have to attach the old wire to the new one. The nice thing about the Vapor Speedo is you can calibrate it to be VERY accurate. They give you 3 different ways to do it. Each one I tried I came up with a different number, close, but different. I added the three together, divided by 3 and used that number. You could probably dial it in closer using a GPS if you wanted to.I wouldn't be afraid to go staright to the battery. The Vapor goes into "sleep" mode after about 20 mins of inactivity and only displays the time. Miniscule current draw in sleep mode. If you go to a switched configuration it will sense a loss of power and switch over to it's internal battery. _________________ 05 Jehm Adventure Buggy 250cc, Torque Spring, 22.5gr Rollers, Modified Roll Cage, K&N, 21x7x10 & 22x11x10 Trac Star Radials, Vapor, Body Panels, 40T Spkt

Thanks for the info im4seven. I understand that the stock "sensor" in the thermostat housing is actually a switch that brings on the "too late, you've cooked it" light. What I want to do is replace that stock switch with the sensor that comes with the vapor. I just don't know if the vapor sensor will physically fit the thermostat housing. (diameter, length, thread type etc).
That's good to know about powering from the battery. Like you said, if I hooked it up to the ignition, the unit will go to internal battery power with the ignition switch off. I guess those internal batteries would not last nearly as long as the buggy battery.

The vapor sensor actually looks like a piece of pipe. The sensor is in the middle. to install it you must cut the hose, slide the pipe in the middle and clamp it. It won't work any other way. Actually looking at the picture I guess you are thinking about unscrewing the sensor out of the pipe. I guess you could try it. Worst case scenario it doesn't work and you cut the hose. I guess you could ask trail tech if the sensor is threaded in or molded in. I think I'd just cut the hose.
We used to extend the wires in house before we sold the Vapors, but it became too time consuming for the price we sell them for. We simply add standard wire spliced in for extra length. It works fine and is cheaper then the extension. A 6 ft extension is available for around $14 however.
It is so easy to add the extra wire though I don't think I would bother. (we are however adding this extension to our page for lazy people LOL)
FYI, the 150cc uses a 10mm temp sensor for the head, and if you havea water cooled 250 or whatever, I much preffer the inline water sensor.
