Aan harness into 3B

[tajgreidotu]

Hi Paul!

Ive done some improvements in this, i´ll post them tomorrow, as I dont have the info here.

Thanks a lot!

[tajgreidotu]

Im going to post my advaces over Puglife post, just to correct all the info and then, post it in his threat.

Here you have all the AAN harness plugs, and I will add in red the plugs where I think they should fit in the coupe fusebox.

AAN Engine Loom

Coding Connector (T6a) 6pin, Black. Has 4 wires connecting to it. On my loom the connector was missing, however I have included a sourced photo of said connector.(Apologies for image colouring, it wont upload properly?)

2 Grey/Yellow (0.5) ECU pin 39 UNUSED
3 Red (0.5) ECU pin 12, branches from F96, G40, G69. ??
4 Green/Black (0.5) Earth EARTH




Here, I also have a sigle spade connector, Green/Gray ???



Two wires with eyelet terminals. One eyelet was removed from my loom but should be
present on black wire.

Black (1.5) 87f on fuseboard. PLUG B, 87F
Red (1.5) Permanent 12v Feed L30?



Data Link connector wires. T2 white connector.

Green/Red (1.0) ECU Pin 55 goes to DLC (L) on Aux panel (i) and T2/2 WHERE?
White/Red (1.0) ECU Pin 13 goes to DLC (K) on Aux panel (i) and T2/1 WHERE?



(T6e) 6pin White plug. Has a single wire connection.

6 Yellow/Brown (0.5) Afterun coolant fan control relay (J69) Pin 4 Coolant pump relay (J115) Pin 5
TC coolant pump relay (J115) Pin 5.



6Pin Light Brown plug, 3 pins have connections. I cant find this on schematics but can locate and label the wires.

3 Black (4.0) Fuse S115, pin 1 B PLUG, PIN 15
4 2x Blue (1.5/2.5) 1.5 – Fuse S116 pin 1, 2.5 – Fuse S75 pin 1 87A
5 Brown/Yellow (0.5) T6e/6 B PLUG, PIN S



Aux Gauge plug (T4m), has two connections to it.

1 Black/White (0.5) Earth?
2 Black/Brown (0.5) Oil temp sensor (G8)

Bulb holder wiring.

Black/Blue (0.5)
White/Blue (0.5)



(T6b) Red 6 pin connector.

1 Brown/Red (0.5) Vehicle Speed Sensor (G22) PLUG T10, PIN 8
3 Black/Blue (1.5) ECU pin 22, Relay position 4/15a. PLUG T5, PIN 4
4 Blue/Red (1.0) ----- nothing-------
5 Blue/Black (0.5) ECU pin 31 PLUG T5, PIN 3
6 Grey/Red (0.5) Hydraulic Pressure Control Switch (F79) PLUG T5, PIN 2



(T6c) Green 6 pin Connector.

1 Lilac/Black (0.5) ECU pin 40. PLUG T10, PIN 7
3 2x White/Blue (0.5) ECU pin 50, branches to T6g/1. PLUG T10, PIN 9
4 Grey/Yellow (0.5) Brake Fluid Level Warning Switch (F34) PLUG T10 PIN 1
5 Brown/Yellow (0.5) ECT Thermal Switch (F76) PLUG T10, PIN 2
6 Brown (0.5) Earth PLUG T10, PIN 6



(T6d) Grey 6 pin connector.

1 Yellow/Blue (0.5) ECU pin 32 UNUSED
3 Blue (1.0) Voltage Regulator, Alternator. TO INSTRUMENT PANEL
4 Blue/Yellow (0.5) ECT Thermal Switch (F76) PLUG T10, PIN 4/T5H PIN4
5 Blue/Black (1.0) Oil Pressure Switch (F1) PLUG T10, PIN 3
6 White/Grey (1.0) Oil Pressure Switch (F1) PLUG T5, PIN 1



(T6g) Blue 6 pin Connector.

1 White/Blue (0.5) Bridged with T6c/3 T6c/3
2 Blue/Green (0.5) A/C Control Head (E87) To A/C HEAD
3 White (0.5) ECU Pin 41 To A/C HEAD
4 Green/Yellow (0.5) ECU Pin 6 To A/C HEAD



Turbo Coolant pump relay (J155) has 5 connections. Blue relay plug. i SUPOSE THAT IS DIRECT FIT WITH THE 3B RELAY

2 Red/Green (0.5) TC coolant pump thermal switch (F98)
4 Yellow (0.5) Fuse S73 Pin 2.
5 Brown/Yellow (0.5) T6e/6
6 Brown (1.0) Earth
8 Brown/Black (1.0) Afterun coolant pump (V51)






what do you think? im in the correct way??

Thanks guys!

[tajgreidotu]

help...... ;(

[S2central.net]

I wont get looking at this for a few days... sorry for delay... lots of other balls in motion

Dont worry!!

Im happy that someone can help me with this!

[tajgreidotu]

Is it possible to use the boost wire for a boost gauge??

[S2central.net]

Not really no... well only an audi electronic gauge... you are better using traditional boost gauge that T's from boost line near the ECU - that is most convenient place.

[tajgreidotu]

Thats the way I was using it until today.

If im right, t6g conector is used for the a/c, so is the one I should use for the climatronic conversion im going to make.

So 4 wires less to match!!

[tajgreidotu]

bump! ;(

[tajgreidotu]

Hi guys!

I´ve made a huge research in this without any progress. In a few day I´ll recieve the AAN ecu, so it would be awesome to have this fixed.

Any help would be appreciated

[tajgreidotu]

Just found this, dunno if this helps :S

Is it possible to use the boost wire for a boost gauge??

It is, try to find a gauge with MAP sensor, that is 300 or 400 kpa...

[tajgreidotu]

Thanks Prj, I´ll search for it!

Hope to have it running at the end of september

[prj]

Well, actually, any gauge that has a linear MAP sensor, which is preferrably 400kpa or more (future proofing) will work.
You will just need to take the feed from the ECU instead of using the MAP sensor on the gauge, fit an in-line resistor, and that's all.

BTDT.
