Well here's the scenario:

I've got a PLX-R500 wideband computer. It is a very sophisticated wideband with several different speed and analog outputs.

I've got one remaining Analog output which I'd like to use to display boost on the wideband. However, I'm unsure where exactly I'd tap into in order to get this reading.

I'm using a Maft-Pro w/ speed density. I believe I need to tap into the map sensor since the AFM is no longer being used. Where exactly would I do this?

IIRC, the map sensor has 3 wires. Would I need to tap into one of these wires?

Thanks in advance (Co-written by Shaeff)

On the map sensor there are three wires one is a ground, one is a 5v source and the last one is the reference wire. I would say you need to tap into the reference wire. I am not familiar with the R500 by any means so I do not know how accurately it will read the signal and convert it to boost. Or if you can configure it to use the specifications of your sensor.
