Parts and instructions for coolant mod:

You need to get a 560 ohms resistor, you can get these from Radio Shack or any electronics store like Radio Shack for your area. It doesn't matter what wattage it is either. I think the one i have is a 1/2 watt 560 ohm resistor. Ok, We need to unplug the coolant sensor harness from the sensor, but only when you have the resistor in hand and ready to do the job of course

. Sorry i had a stupid moment! Anyway with the resistor in hand crimp the ends of it over to a loop like how a staple does it when it is put through paper. This is just my perfered method so it won't come out when your driving. Place the resisor in the coolant temp sensor harness. You will know when it is in there and working because if it is not in there right and the engine is running then both coolant fans will come on high speed and the rpms will rise slightly, not to mention there will be a cel. This is all do to the computer not seeing a coolant temp reading. If the resistor is not in there right it will also dump fuel.Lastly Make sure to wire you fan on. I have mine wired to the key. THATS IT ALL DONE!!!!!!!

I have a 1995 Mx-6 ls v6 so i have only experimented this with OBD 1 vehicles and that where 2nd gens. I would imagine you could do this with OBD 2 but it will most likely set a SES ( Service Engine Soon light) or cel what ever way you want to pronouce it. I would also think this will work with the 2.0l but it uses a different type of sensor for mesuring air.
Correct me if im wrong, but i think it uses a Maf instead of a Vaf like the v6.

If you have any futher questions, things that i did not cover in here you can pm me.

Have fun,
