# PnP adapter board

![Isometric view of adapter boaard together with proteus](https://rusefi.com/forum/download/file.php?id=5673&sid=1df371e40697c38dca9221e44ce28b50)

A plug and play adapter board has been developped to get the car to work as easy as possible. It only requires sourcing a tock harness plug and Ampseal 23 pins headers if you want auxiliary functions.

## Pin mapping

## Interface with proteus

At the moment, the interface between Proteus board and the PnP adapter is handled by hacked up Ampseal connectors. To do that you need to source the male connectors used on Proteus, and cut the plastic shroud on the connector side, flush with the watertight seal if there is any, or with the mounting flange.

A better solution for that would be to source rows of headers with the correct pitch.

## Pricing

Unit price for QTY 5 assembled and delivered to Europe is 7$.

## Auxiliary inputs

### MAP sensor

Using an external MAP sensor allows you to get the engine running above ambiant pressure when using forced induction. Good cheap option is GM 3 bars but anything will work for you. MAP input can be mapped to Analog Volt 1 (A13 pin).

**Note :** 
You can also run the engine naturally aspirated using the OEM "boost sensor". It is located on the EGR systems and is used by stock ECU to determine whether the EGR is working or not. You've probably ditched EGR so far and so you can run a vacuum line from your plenum to this sensor and use it with this calibration:
* 0V - 15Kpa
* 5V - 115Kpa

Or you can use the OEM sensor for barometric reading and correction.
