My car came over on the boat with this installed, after doing some digging, I realize its an RE:Amemiya fan mod, but google translate doesn't help much, and my Japanese isn't that great. Does anyone have any idea what this mod actually does?

??????????

 

The link just takes you to the home screen and I don't see under any of the menus where they have a fan kit.

Post a picture of it

 

That's weird, it links me right to it. I've attached a screenshot of it below.

Here is the description for anyone who's kanji is better than mine (I can read the hiragana and katakana but my vocabulary isn't enough to make sense of it)≪１型～４型社［作動方法］≫

It is set to switch to the normal circuit.



〇 You can easily check the switching of the two-color lamp on the switch.

〇 With attached parts

〇 It can be used for other than cooling fans! !!

〇 For F-con, power FC, and other full-con

Operation is unconfirmed.

Not many clues there. But from looking at the picture it's most likely just a simple relay with a switch, you probably wire it in to manually turn on the fans. Considering they keep saying something about AC I think it may tap into that circuit so the fans run all the time like if you have the AC on.

I recognize that switch, that's just a cheap switch I've seen in fog light kits from the 90's. This is nothing special that they have, you could get something of better quality for $20 in parts.

Get an FC fan switch, lower the fan temp in the PowerFC, run a Koyo, and your cooling system will be happy and healthy.

Yeah, I looked at the google translation myself, It did not carry over well.

Now that I think about it, I've noticed with that switch "on" the car usually runs at 84 degrees C in daily driving. On a hot day with some spirited driving it may get up to 94. So in actuality I think my car runs pretty cool most times, I'd imagine it has an upgraded radiator if it's running those temps.
