Identification of E46 engine bay relays

Recommended Posts

I'm having a wiring tidy up as part of my VQ engine swap to see if I can keep the OEM relays and maybe fuse module etc. Have been struggling to match up online images / descriptions and many various configs and layouts form newtis etc. If somebody could confirm my current thoughts and fill in the blanks that would be great !!!

Car is an E46 NZ new 318Ci (M43 i believe) with auto trans (swapping to manual). DME is a Bosch BMS46 as far as i can see.

Current thinking and questions (please confirm or correct):

- Light blue relay is DME

- Light green relay is ignition coil

- Dark blue relay I'm not sure ... looks to switch 12v when key is 'on' (via DME relay) to blue/yellow on the 4 pin connector within the connector shown in the picture. This is marked as a ground currently but this may not be right ? Will need to trace

- Is there an unloader relay anywhere !?
