Help with chassis plug

[KieranC]

Hi fellas,

Can anyone help identify what pins are what, the guides on here and the saxo forum say the later model 3 plug ecus used 3 different pin configs but the one i've is completely different.

its a 1.1 independence 2000 model. Any help or information would be much appreciated.

Cheers

There are only 2 pin configs for 3 plug ecu models.

crossover loom and non crossover loom

Looks very much like a later style 3 plug to me. your plug isn't completely different.

The pins are numbered on the guide left to right, starting at the top. The top left most is no.1 and the bottom right most pin is 37.

A multimeter is your friend.

Ah okay thanks ill spend some time today going through it see if i can't make some progress ID'ing the pins not on the guide.

The guide says that the later 3 plug models this should be the pin out:

Also worth stating that all the wire numbers have rubbed off!

Try this one. obviously being the 1.1 it won't have the wiring for the oil level and coolant gauges.
