DME harness that supports wideband o2?

[Leo95se]

I have an e46 race car that I am converting from an aem ecu (the adapter module died, last string with that damn setup), back to oem. The engine harness is mostly intact and an easy swap. I’m seeing with the dme harness it’s a bit more tedious. I have (2) wideband o2 sensors now. I’d rather keep them and get a harness that will support the 6 wire connections.

I’ve read a z4m harness will work? Can anyone offer guidance or more detail?

thanks a ton!

I can confirm that the z4m uses two wide bands for fuel tuning so the harness must support them however z4m uses a different dme to e46 so the harness may be of no use to you.

The harness isn't the thing supporting the wideband sensors, the DME is, the Z4M runs on the MSS70.
So a Z4M harness is useless without a MSS70, and also that harness simply isn't designed to go into an E46, the routing is different and so are some of the other sensors.

In summary, install normal sensors.

Got it. That’s my plan. Thx all
