Fan not turning on

Fan not turning on
Today I got my car started for the first time on the MS in standalone mode! It idles a little rough and unstable but i'm yet to tune it. I do currently have an issue with my cooling fan not turning on though.
I built my MS1 v3 standalone for my 94 1.8 miata and followed brain's guide for the fans mod. When the squirt is plugged in (on both the stim and in the car) and the temperature goes up, the LED comes on indicating that the fan is activated. I can see that its been activated on megatune too. However the fan on my car does not come on and i dont know why.
I've wired pin 29 on the DB37 to 1L in the car (Black and Green) which is for the cooling fan. Any ideas?
Just out of interest, how come on the megasquirt it shows 2 fan controls?

My wiring is the same and my car is RHD (which i think you meant to say)
I just found a post by you brain here: https://www.miataturbo.net/forum/t31501/
I feel a bit because I didnt solder the wire between the middle LED and IAC1B. I'm guessing thats my problem right?
If it is, you might want to upload that same pic into your build thread as I was following your build thread and it had no mention of that extra wire.

We are having this same issue. I double checked the fan mod and the wiring harness. We for sure have the output going to the black and green wire and everything else seems fine.
Originally the mod was setup to JS0 on the board and we changed it to JS3 thinking that was the issue. It turned out that the wire on the standalone harness was going to 1O instead of the 1L that was necessary.
Now that we have it all hooked up the fans turn on but they turn on as soon as we turn the key on regardless of what temperature settings we use in megatune under the JS3 output.
We are now going to switch the fan mod back to JS0 to see if we can make that output work correctly.
