MAF Delete

I’m getting ready to remove my MAF from the car and was wondering if anyone makes a wiring harness that goes from the 5 Pin factory connector to a 2 pin that plugs into a temperature sensor. If there is who sells this?

Also what temperature sensor are you using for FI that will be either welded or screwed into the intake tube? Is there a part number for the bung and sensor that I can order?

Thanks

You should be able to just tap the pipe and screw it in, but if you want more strength, maybe you can weld a small plate to your pipe and then drill and tap it. There's no real tension on the sensor, so you just need it to stay in place and not leak.

2 wire pigtail from an earlier vette.Just solder it into the harness.
Temp sensor from a 1990 Cyclone truck.
3.5 or 4" pipe. Drill/tap for 3/8 pipe thread for sensor.
Pretty easy.

Although I don't have info handy, picture circuit as a voltage divider, because thats all it is. The thermistor is simply a temperature dependent resistor or resistance changes with temperature. There is no polarity to reverse...

Thanks for the reply, I'm getting a wiring harness made with the weather pack connectors to go from the 5 pin MAF to 2 Pin IAT. I also picked up a screw in IAT.

Thanks
