Rite, my engine management light is on and the car is running in safe mode Took it down to a local bloke and he plugged it into his diag equipment through the plug in the Fuse pannel and there was no reading.

Would that plug possibley have been bi passed and the necessary plug be situated somewhere else?

Also how do i found out what ECU the car is running?

This car has a Diagnogstcs port trust me, and if the EML is on its nothing too serious prolly a dodgy sensor or summat

there's a guide to doing a paper clip test in faq and tutorial section.

i think most conversions still enable the diagnostics connector.
