MAP sensor (9F479-AA) 4-pin connection question
Hi,
I'm afraid I don't have a Ford but I was hoping you would be able to help me. I have shoehorned a Chevy V8 into my 1990 Supra
and I am making a data logger in order to tune the carb (to try and get my mpg from 4 to 6!). I have a 1N1A-9F479-AA MAP sensor which I will use to measure the inlet air pressure in the carb however I can't find a wiring diagram for it. It is the 4 pin sensor. Does anyone know what the pin connections are and what the input voltage is (I assume it is 5VDC). I've searched the forum but couldn't find the relevant info.
I chose the 9F479 as it was the only one I could find the pressure/frequency data on (link) but that only shows the 3 pin connections.
Any info would be much appreciated (I hope you don't mind an imposter asking questions).
Here's a couple more pics of the car and a video of it at Rockingham

Thanks,
Mark
