I bought this under the image impression that it came with the fuse holder and fuse along with everything else. It does not come with the fuse holder that's clearly shown in the images... I know its not a big deal to pick up a fused link but it's the principle of it all and added costs on my end, fuse holder is shown clearly in the images so it should have arrived with my wiring relay setup.

Works like it's supposed too! Make sure you follow directions because the relay does not wire like you would expect! Great buy!

bought it for the 1/8th pipe adapter, but used entire pkg. easy instructions. 25A rating was twice what I needed. should last a long time.

Just as expected! The wiring is very simple, I managed to hide most of the wiring and I feel confident in this kit. I plugged the brass fitting into a water port on the engine and it manages the fan itself. No more wondering if a prong is still plugged in the radiator, no more engine running for 2 seconds after the key is off....as the relay controls the power

very nice looking kit but if the thermastat doesn't work it's not much good now i don't trust it 40 bucks to replace the thermastat with one i trust i should have bought a different kit

I bought this to use with the Hayden Automotive 3700 Rapid-Cool Thin-Line Electric Fan I reviewed previously.This thermostat is a little more difficult to install than one in which the probe simply slides into the fins of the radiator. None of the included thermoswitch adapters would fit existing holes in the radiator, so we simple drilled a small hole into the plastic endcap and used the sensor itself to cut the threads. It works great. The fan cycles on off as the coolant reaches normal operating temperature.The one feature I really appreciated was the AC bypass connection. Connect this wire to the AC clutch and the fan will turn on when the AC compressor turns on!

This is the one to buy - the other one from Derale that has a radiator stick probe that goes in the fins isn't as good ... buy this one because you can thread this directly into a water passage and get a direct measurement. Has worked great for a few months now and would definitely buy again. I am using it with a non-Derale fan so no problem there, either. 25A max on the fan current, should be enough for most fans 16" size.

Picked this up for my 67 GTO to turn on my additional electrical fan. It seems to kick on about 10 degree's later than advertised but it does work.It's looks a little out of place on the front manifold but not much I can do about that other than find a manifold with a plug in the rear (which mine didn't have).Install was easy and it doesn't leak.Would buy again- 1 star because it turns on a tad late
