I have a PI Research air pressure sensor and PI Research wheel speed sensor left over from a project; the links below show the full sensor specs on the PI/cosworthwebsite:

The wheel speed sensor has never been used and the air pressure sensor was used on the car only two or three times (about 10 hours running time total). They both have 5 pin male Deutsch connectors on the end.
Air pressure sensor £250 ono
Wheel speed sesnor £50 ono
