I have a stock 91 hatch std (dpfi/d15b1) and would like to monitor my iat in realtime. Does anyone know which wire on the iat sensor i need to splice into with a wire that would go to my multimeter? Appreciate any help! Thanks, frank.

 

the red/yellow wire goes to the ECU - the green/white is ground

 

totally correct

 

just ran red to neg on meter, and green to pos. reading was zero when i set it at 200 ohms, and 2k ohms. Then i switched the dial and then back again, and it would read approx 1k ohms on the 2k setting and 200 ohms on the 200 ohms setting. It only reads for a second and then switches to zero, so i have to keep switching the dial to get a reading that lasts a second or so. This normal? the 1k ohm reading translates into approx 105 degrees fahrenheit which seems normal for a reading with the intake hose sittting 3 inches away from the em, a couple minutes after a cold start. Just don't understand why the reading only lasts a second.
