Hello can anyone help me.
I know information on 146 Fiorino MK2's is hard to come by but I was wondering if someone on the forum has a wiring diagram for a 1999 1.4 motronic injection van or any other technical information.

Thanks with hope.
Nigel.

Bosch says that the 35-pin ECU in our 146 engine is also used in the Tempra (and apparently the Tipo) so, after tracing the wiring with an ohmmeter I can say that the following diagram posted by 'varesecrazy' is accurate for the Bosch 0261203839-ECU

I will soon edit it to add the missing part's names and ignition

here's the edited version, feel free to add missing info
