Bit of a long shot but wondered if anyone would know....converting my ecu to an Emerald M3DK at the weekend and planning in advance to get it done as quickly as possible. I've only done mems2j vvc to Emerald in the past and can't remember what I did with the screened wires for the O2 sensor and Crank sensor, mems pins 28 and 17 respectively.

I don't suppose anyone knows the corresponding Emerald pins for these?

If all else fails I'll just look at what I did with the track BRM or MGB when I'm at the unit but would have liked to be prepared.

Nothing jumps out but I don't have access to the wiring diagrams.

Trying to remember what I did withy them, I think just ran to earth so will have to double check on the BRM.
