GM MAP and IAT sensor to miata wiring
 

is there a schematic or diagram somewhere? Or can someone tell me which wires go to which on the 96 miata?

Thanks

Did you get the plug and play loom? If so, Travis should be able to send you the install doc with the wiring. With my setup I used the IAT wiring from the sensor on the airbox for the GM IAT. I wired in the MAP sensor on the plug and play harness itself since I already had a vac line going into the cabin.

Cool Thanks.

BTW 96 is differnt than 99. single 5 wire plug for MAF. no IAT in OEM configuration. so IAT and MAP wires to it. except the 5V (goes to TPS).

I had it up and running before, but I swapped to OEM over the winter and havn't messed with it in a while. and I forgot to label the wires, Duh. thought someone might be able to rattle the colors off for me.

I think I got it though.

MAP =
Orange/signal Red w/white stripe
Black/ground Black w/blue stripe
Red/power Spliced 5V from TPS not wired to harness


IAT = 3rd and 4th MAF pins, polarity doesn't matter.

Let me know if I am wrong.

Hello Guys,

Is there a wiring diagram that show in detail how to wire the IAT to the correct wires from the car as well as wiring the MAP correctly?

Also do I need a different TPS sensor, or does the one on the car work still with the wiring change?

I have a 1995 Miata that I plan to turbo but I want to get the wiring sorted out.

I plan to use the MegaSquirt ECU.

Thanks

wire the AIT back through the MAF connector.

you do not need a different TPS sensor.

This is the Adaptronic forum, but you still want to go MS?

Hello,

I apologize! I did not know this was an Adaptronic forum.

My goal for right now is to really understand how the wiring works (when I turbo my 95 Miata) for the AIT, MAP sensor (if I do not go with the MS) and the TPS.

I have been doing a lot of research and found some other thread taking about this but I just wanted a little more detail...

Thank you and please let me know if there is another thread I can view for this type of question.

AIT goes into the MAF connector.

MS has a MAP sensor built in.

Nothing needs to happen to the TPS.
