Pi (COSWORTH) X-SPORT DASH
Hardly used and working perfectly.
Can be mounted inside suitably sized steering wheel.
Comes with new Deutsch connector (was £65) and has all the necessary pins populated for standalone use.
New Cosworth speed-sensor (not pictured - was £50).
Military grade wiring - all pins numbered.
Installation guide is freely available online.
Stupidly expensive when new... £275 please, and I'll throw in free UK delivery.
