Hey terra, would you happen to know the part #'s to the wiring connections for the 2 and 3 pole female connectors that connect to the flap. Here's what I've got:
2 pole:
12520007172

3 pole:
12520007170

Now the problem is when I input those parts #'s into ECS I can only find 10pks of each that still match the part #. The individual flying leads (some pictured, some not) come up as different part #'s.

EDIT:Also, the 2 pole female connector is the same one would find on and IAT and I think the fuel injectors as well.
The 3 pole female connecter is also found on the TPS.

There are different part number for the wiring connections because the 3 pole has wider spades on the male side of the connection that the 2 pole. Getting into the weeds here...hopefully someone can follow.

classic thread

Can anyone help with the part #'s or link to the parts? I need the 2/3 pole connector lead, whether crimped as a flying lead or just the connectors themselves I don't care. But the 2 and 3 pole definitely have different size connections.

I’ll just post here rather than respond to your PM- but if you ordered the part numbers listed in the first post, they use the same contacts. If you got the 2-pin connector from a generic manufacturer or some other part number, then it might not.

Hey, For the IAT sensor pin 22 and 25 are currently used, do i just unplug those pins and put the 2 wires from the iat sensor in?

**Cubieman** · 05-12-2020, 06:00 PM

You may have to splice rather than de-pin/re-pin. However to my knowledge if running CSL software you de-pin 22/25 and re-pin your IAT.
I am not sure what pins 22/25 run to, I would find that out first before de-pinning.
I thought it was the MAF, but that does not look to be the case.

I was running a alpha N tune before I decided to go with csl dme and map sensor, so my IAT was already wired. I wired it but cutting #1 on the maf and soldering it to the IAT wire. Then I spliced wire #3 on the maf with the other IAT wire

**Jake.s54** · 05-12-2020, 06:35 PM

I am still very confused on if I need to change that wiring for the csl dme. I did not cut the MAF off entirely, due to me maybe going back to stock eventually.

**Cubieman** · 05-12-2020, 07:09 PM

I would follow the wires and/or do a continuity test to confirm where pins 1 and 3 on the MAF terminate. You may find your already wired into 22/25
EDIT: I know this from my recent airbox install, x6003 pin 17 = MAF ground.

You could (likely) tap into ground anywhere you can find one on the connector block. Pin 16 is unoccupied and I used it for the ground on my MAP sensor, I also believe terra is currently using pin 16 for his IAT ground. However, another user, JBfrancis found that using pin 16 for his IAT ground caused erratic/incorrect readings to the DME, so be aware of that.
It HAS to matter where you get your power from through, and maybe ground as well for that matter. The IAT is simply ground/power, no signal wire, but it obviously has to communicate with the DME in some fashion. I wish I understood that better.
How does a sensor such as the IAT communicate with the DME without a signal wire? Resistance correct? I know the hot tubs we sell the temperature sensor is two wires and it just sends resistance values back to the circuit board where its interpreted.

But it must matter where at least on wire, or both plug into. Maybe it isn't as simple as ground is ground? Otherwise one could draw power/ground from the battery, I don't think that would work so well

**Jake.s54** · 05-12-2020, 07:52 PM

okay so I just tracked the wires down. Pin 22 wire (Yellow and blue) in the dme runs to pin 1 on the maf (the one I cut and soldering in one of the wires from the IAT). Pin 25 in the dme (brown) runs to pin 3 in the maf (the one I sliced into and soldered)

**Cubieman** · 05-12-2020, 07:59 PM

OK, so it sounds like your good to go with your IAT wiring the way it sits now.

**Jake.s54** · 05-12-2020, 08:01 PM

Hopefully, and I will test it through a app on my phone to double check everything. Just waiting on my USPS package with my DME and Map Sensor ughh

**Cubieman** · 05-12-2020, 08:48 PM

You'll be fine man, IAT is done already, just three more wires for your MAP, unless the flapper doodle is in the works for you.

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.

Sorry to revive this, but I bought the Turnermotorsport IAT relocation harness. I’m doing the CSL box, running a MAP, but can I still use this harness for the IAT, and not have to plug in the MAF portion?
