IDK, if it comes on with the AC on Max. Since I swapped out to the a9l, the low speed comes on as soon as I put the key on. We peeled the wire, then crimped it, so the crimp should be on pretty good. What about the 2nd post in this thread?

The problem is that since my LOW is coming on automatically, would that trigger a 'medium' setting since both would be on, like CManT said? And what do I need to do to fix it?
Uggh, you have the fox puter installed already. Did the kit come with a fan controller? There are a *select few* A9Ls that can actually trigger a cooling fan with the ECT alone. Most of the time one needs a stand-alone controller.
On a T4 puter, if your ECT circuit was open, low speed would come on by itself (as a safeguard. The computer actually needs to be active to shut-off low speed. That's why there is an EDF relay control). But since you did the PIH swap and I have no experience with that, I'll bow out except for specific questions about one or the other computer system (I'm pretty conversant with the ECT and fan pathways for both individually).
FWIW, Chris talked to me before doing his fan switch stuff.
Please note (not you Nacho, but everyone) that the info about using a 3 way switch in his post is wrong. You cant do that since low and high speed use different polarities (ground for high and 12 volts for low).
You are correct - if you engage high and low speed simultaneously, the fan runs a little faster than low speed RPM's, but it has a large electrical draw - dont let that happen.
Ok, for a solution:
if your low speed comes on now and you're happy with it except instead of it being low speed on, you'd wish it was high speed you could try: Just remove the fan connector and rewire it so that the low speed fan harness terminal goes to the high speed fan terminal (instead of low). I actually considered this for a one-week fix while waitin for my controller but never did it. So try it at your own risk.
You very well might want to run stand alone relays and even a stand alone fan controller. This was the point I reached, and after I considered the price to do relays and a controller decently, I thought it much better money spent to use a Dc Controller. You could literally just use two relays and two switches and probably wire it up for 20 bucks or so.
Good luck.
