The blacktop and facelift silvertop ecu's have a cooling fan pin labled CF.

Is this pin to let the ecu know if the cooling fan is running? or do the ecu's drive a cooling fan relay?

Here are the pinouts:

From my experience, the ECU does not drive cooling fan, it is probably is for ECU to compensate for electrical load when fan switches on. Prefacelift AE101 lacks that pin from memory.

Yea but on the blacktop, ELS1 is the cooling fan relay

Hi there guys, sorry to hijack, but I have a smiliar issue. Anyone know which terminal tells the ECU to idle up when A/C is turned on. I need to wire this to my Link as it is idling very rough when I turn my A/C on. Cheers

I'm pretty sure Sergei has got it right - it's additional idle up if the cooling fan is on.

BZR4AGE - Unplug the VVT solenoid and turn on the aircon as it could be the VVT solenoid operating when you're switching the aircon on. Just turning on the aircn shouldn't make it run rough - just the idle should drop as the aircon load comes on. According to some pinouts from Phil Bradshaws page I got ages ago it could be any of the following outputs:

12 pin plug "L" - 5, 6, or 10. Most likely 6.
26 pin plug "N" - 8, 19, 20 or 21.
These are the ins looking at the face of the male plug with the locking tab at the top:

Manual Trans Plug ‘L’ Pin 1 2 3 4 5 6
PCB Code +B1 BATT CCO AC2 A/C
PCB Code +B W EGW AC1 SPD ELS1
Pin 7 8 9 10 11 12

Manual Trans Plug ‘M’ Pin 1 2 3 4 5 6 7 8
PCB Code THE VS THA THW OX TE2 VF
PCB Code E2 VTA VC IDL OXL1 KNK TE1
Pin 9 10 11 12 13 14 15 16

Manual Trans Plug ‘N’ Pin 1 2 3 4 5 6 7 8 9 10 11 12 13
PCB Code ELE2 STA IGF NE G2 VVT ISC #3 #1 E01
PCB Code HTR IPV G- G1 L3 L2 L1 IGT #4 E1 #2 E02
Pin 14 15 16 17 18 19 20 21 22 23 24 25 26

Hope this helps. I can email the pinout file if you want it.

Unless your running toda non vvt pulleys and 304deg cams.....

Yeah I was gonna mention that too.
