Urgent where is the laptop diagnostics connector

[monty quick]

Car has conked seems like electrics. If I leave it it starts just. Runs for a while then stops again. Mobile mechanic is here but doesn't know where the laptop connects

Its a 3 pin wire under the dash above your right knee.
Not sure what the mobile mech is going to be doing with it tho... without the right software and know how...

Fuel pump conking out? Check fuel pump relay. iirc its the brown one at the end of the board.
Have you washed it recently or driven it in heavy rain?

You were ((of course) correct and although he tried hard he knew nothing!

He would be looking for an OBD connector - no such thing!
