Yes, just simply leave the MAF connection unused, I've got the same Turner Harness. Had I known they had one w/o the MAF I would have bought that, less engine bay cluter.

Did anyone confirm the part number for the IAT connector 2 pole wiring leads? Had my friend order part number #12520143433 and it looks like the bushings at the end of the lead are pretty thick. I imagine they compress a lot but waiting to hear back if this works.2003 E46 M3 TiAg/Cinnamon 6MT

Pin 1 on MAP connector
Goes to X6003 Pin 7 = Power
This spot will be occupied by a red/green wire, tap into or better yet, solder into wire. Not sure where this wire goes to.
Pin 2 on MAP connector
Goes to x6003 Pin 17 = Ground
Pin 16 which is unoccupied worked for me, you could de-pin 17 so long as you are not using it for something which it doesn't sound like you are. Pin 17 provides ground to the MAF.
I used the Turner IAT relocation harness for my IAT wiring (cough, plug in) job so I kept pin 17 as is and used 16 for MAP ground.
Pin 3 on MAP connector
Goes to x6003 Pin 18 = Signal
This spot will will be unoccupied on the connector block
Just make sure you have your battery disconnected when messing with any of this, especially the DME.
Also, DON'T do a continuity check on the DME like I did with my multimeter!
I disconnected the battery, pressed the brake pedal in an effort to eliminate any potential remaining charge, wore gloves then I proceeded to introduce anywhere from 3-9volts straight into the DME with my Fluke via the continuity test. Just simply wasn't thinking. Quite glad it didn't smoke my newly bought DME.
If I didn't, does anyone have a photo of a stock X60003 gray connector I can use as reference? lol
I probably should have taken a photo of it before I started messing with the pins.Last edited by zzyzx85; 08-07-2021, 09:14 PM."your BMW has how many miles!?"

Can anyone here confirm the part numbers for the following:
1) 2 pole connector contacts (with or without flying leads)
2) 3 pole connector contacts
3) connector contacts needed to terminate at the DME
Contacts without flying leads are preferred for the most OEM like setup, but I’ll take what I can get. Thanks‘02 332iT / 6 | ‘70 Jaguar XJ6 electric conversion

So I have a question, on the threads that they talk about IAT relocation for non CSL setups, they indicate on the MAF connector pins one and three are the IAT wiring Not polarity specific.
Pin 1 goes to x60003 pin 22 (signal intake air temp)
pin 3 goes to x60003 pin 17 (ground air mass sensor)
So what's wrong with just wiring your CSL IAT to pin one and three on the MAF connector?
This is what I did so hopefully it's okay and works
Why are all of the IAT wiring guides that I find saying to route the IAT wires to x60003 pin 22 (signal intake air temp) and pin 25(common ground for Ground Coolant temperature, Shield, knock sensor) directly
Since the original IAT for the MAF connector went to pin 17 on x60003, I opted to use pin 16 for the ground for my map sensor so that I don't get any weird interference with the map sensor ground in the iat ground being combined. I wanted map to have it's own dedicated ground

For the OEM CSL IAT I currently have this sitting in my cart,
12521427615 - 2 Pole Connector
12520143433 - Contact w/ flying leads thegenius46m Was your friend ever able to confirm these are the leads that plug into the 2 Pole connector?
Just need to confirm these will actually get the job done.
