On the 99 diagram I see one by the ThermisterTag says 8-13-1999 made in Canada so I'm assuming it is
I stand corrected - the 99 does have one - wired differently, but serves the same purpose - it is supposed to turn the fan on when the fan thermistor reaches 260*F, turns the fan off at 240*F and turns on the hot light if the oil temp rises above 290*F.On the 99 diagram I see one by the Thermister
The module itself was smoking and is burnt where the orange, red and yellow wires go in. The fan ran constantly and the red temp light stayed on.

Is this the problem you are having? You test the thermister and LR60 module by shorting the thremister leads together - if the fan and hot light come on, then the LR60 module is good and the thermister has failed or it simply has not gotten hot enough to turn the fan on.
You can test the thermister by suspending and immersed in oil (cooking oil will work), connect an ohm meter to the leads and using a candy thermometer, heat the oil - the resistances should correspond to the chart.

You did not describe the problem, you simply asked if the unit does no longer exist. The unit is not a relay, it is an electronic control module that uses IC's and Zener diodes in place of mechanical relays.
Although made in 99, it could be a 2000 model - the VIN will determine and settle that question.
Huh Engine serial checks. Bought it new in Fairborn Ohio but my tank says 335.Polaris says that VIN is for a 2000 Sportsman 400 lol
VIN Search Results
Engine Serial Number
Ok ThanksIt's not at all rare - just Polaris errata
The VIN reveals it's a model A00CH33AA - 2000 model Sportsman with a 335 engine in color AA (OLIVE GREEN)
Now is when it gets interesting - there were early and late production models - while they both had an LR60 module, the early production was a 6 wire and late production was 5 wire - so based on the production date and the 6 wire unit, I will deem it an early production model. The bad news it used the same 4010164 LR60 module as the 99.
I suggest you first try to find a used LR60 module - if not successful, find a thermal switch that fits the thremister hole in the oil cooler to turn the fan on at about 250* - it will eliminate the hot light function and it will have to be rewired - the org/blk wire will go to the thermal switch and the oil cooler will have to be grounded to get the fan to turn on if using a single connection switch - or wire in a manual toggle switch. There might be other options, but the ones suggested are the fastest, cheapest and easiest.
