All,

With all your help I've got my 97 miata running fantasticly.. except for one small detail. Apparently the fans don't come on. I expected the stock ECU to kick them on, but it's not happening.

I am going to go to a standalone configuration to simplify the situation.

From the wiki I see the easiest way to control fan is D15.

From the photo here.


Do you remove D15? I assume that you no longer need JS0 connection or the Diode.

I do however need to put the diode on the harness between the AC fan and the standard fan..

If I want to test the fans without a computer plugged in, do I just give 12V to 1A and 1B?



Thanks again!

If you want to test the fans operation, open your diagnostics connector and jump TFA and GND.

the ECU controls the fans, so if you have a MS running the show, it needs to be modded to run fan control...you should only use the D15 circuit for fan control if you've replaced the 3904 transistor with a 2PN2222
