S52 3.5” Bremi HFM Upgrade Wiring Harness OBD2

[Jknightindy]

Found out late last week that Turner Motorsports is no longer making the wiring harness adapter for the Porsche 3.5” HFM 803 or 809 upgrade. I have a ‘98 E36 M3 and I had an order in since May (part of their upgrade kit with intake, injectors, tune, etc… and this singular part has continued to get backordered. Received a voice mail 8/12/22 that their supplier has decided to no longer make them. Can anyone assist with other suppliers for the harness or maybe a source for the end plug that goes into the HFM since it is different? Much appreciated.

Has anyone modified their own wiring harness to work with the Porsche 3.5" HFM/MAF? Thanks in advance.

hi did you ever find out any info on the harness adapter ?, it possibly could be made as long as you have the connectors and the pin layout
