I installed a manual low-speed fan switch this afternoon. I have the switch mounted for the high-speed fan, but didn't get around to wiring it. But even with the low-speed fan on, I don't see above 192* now. Engine runs a LOT cooler, and it only cost me like $15 for both switches and in-line fuses. I'm gonna finish wiring the high-speed fan tomorrow.
The right switch is the low-speed fan switch, the left is the high-speed (which isn't wired yet).
And here's where I run now.
For those of you who want to do it, here's some tips.
A good spot for the switche(s) is in front of the shifter in the bezel, a good amount of room behind there, and you have a ground and 12V source right there (power point). Another good spot, although I would recommend it only for coupes, is in front of the center console, above the foglight switch (and convertible switch if applicable). I wouldn't recommend using this as a spot for a vert however, because the only good close 12V source is the 'vert harness, and vert guys are using this. And if you're like me, then you already have your foglights wired into this also. The fan might be to big of a load for this single wire.
For the switch, you can use a 3-way toggle switch (for high and low-speed on one switch) or use 2 different rocker switches. If you use a 3-way, hook up the wire from the Pin 14 to one terminal, Pin 17 to the other, and then of course a ground (according to the write-up in 94/95 FAQ section, I'm not positive on this, as I used two seperate rocker switches). For the 2 individual rocker switches, on the low-speed fan switch, hook a 12V source (preferably ignition-hot only) (or use the one for the power point, it's constant hot but that's okay) to the power terminal, a good ground (like the one for the power point in front of the shifter) to the ground terminal, and run a wire from the accessories terminal to Pin 14 on the CCRM (dark blue wire). I'm not exactly sure how the high-speed fan hooks up yet, I haven't wired it. But I think you're supposed to run the ground to the power terminal on the switch, then the wire from Pin 17 to the accessories terminal, and I guess the 12V lead goes on the ground terminal. I will verify this information tomorrow hopefully.
I would not recommend using the power point while you have one of the switches turned on, it might be to heavy of a load for it. Better now risk it. If anybody wants more pictures, let me know tonight or early in the morning, cus I can take more tomorrow while I'm wiring the high-speed switch. If anybody is thinking about doing this, don't be afraid!! I was a little unsure of doing this since I'm not very good at electrical stuff, but it was SUPER easy! If you can wire gauges, you can sure as hell do this, lol. Let me know if you need some more tips, I'll be glad to help.
