MX-3.com

Hello, i have a 94 mazda mx-3 , came with airbags, etc. I'm running a megasquirt standalone, stock ecu is completely gone, so now when i press my a/c button on the HVAC, the compressor nor the condenser fan will turn on. I tried to read the wiring schematics on the online manual, but i cannot decipher what i need to do to get it to work like stock. I do not want to use a toggle switch, want it to work like stock. Please help, any help would be greatly appreciated. Thanks

The factory ECU controls the A/C (and the cruise), when you go standalone, you lose them....

You can run a switch/relay setup separately to control the compressor on/off if you like.
