155 HGT ECU - Help needed

[Rob]

Hi,

Continuing with my HGT lacking power thread, I took my car to a local garage for diagnostics checking. The garage is a Bosch specialist but could not connect to the HGT ECU. The garage can test the Bosch Motronic M2.10.4 (147 HGT ECU?). Few questions:

1) Is the 155 HGT ECU a Bosch Motronic ME3.1?
2) Is the connector the 3 pin?
3) Where is the connector?
4) Can only a Fiat dealer connect to the 155 ECU?

Any help is greatly appreciated as myself and the garage are stumped on this one.
Cheers,

Rob.

When i had diagnostics done he plugged it in under the bonnet. There are 3 plugs the same and he tried them all till he got the right one.
When you've got the bonnet up, looking towards the back they are in the top right corner of the engine bay next to the fuses.
Dont know about the rest sorry.
Mines a 155 HGT aswell so it should be the same.

A local garage to me was able to run a diag test on my 155, and they're not a Fiat dealer.

As James said above, there are 3 plugs around the large black fuse box cover.... it's one of those.
