Cooling Fan Circuit - Overide

[vicankim]

As I have the dash off to replace the alarm system, I want to fit a manual overide switch to short out the Otter without laying cables in the engine compartment. Does anyone have a circuit diagram for a 97 Chimaera 500, showing the relevant wiring behind the later style dash?
The bible is no use as the only circuit diagram in there does not give this detail and the overide arrangement it suggests is clearly wrong as it omits the relays.
The crucial question is what is the colour of the +ve connection to the Otter switch?
In order to incorporate a fan (supposedly) running light, what is the colour of the feed from the main power relay(s?) to the fan itself?

Yes, I know there are a large number of previous threads on this subject but none appear to answer the above. One does suggest the answer to the first question is green/pink but I do not have that colour wire.

Help appreciated

Hello
Green/pink trace is supposedly the correct colour to be looking for, I have seen green/white trace mentioned but a faded light pink colour is very close to white hence there could be a mistake being made there, I,ve also seen black/orange trace mentioned but can't remember where or when.
Green/pink trace is the correct colour going by most peoples findings
You won't be able to wire a warning light at the relay fan output cable as this method creates a problem of the warning light glowing when the fan is being driven like a windmill (happens at approx 60 MPH)
There is another problem with wiring a warning light at the relay, the warning light only informs the driver that the relay is switching a +ive out, this method doesn't mean that the +ive out is getting to the fan motor

The wire from relay to otter starts as Green/Pink at the relay(s) but goes through a clear plastic connector (pin 17) but comes out the other side as Purple/Black (just to confuse the unsuspecting).

on my 1998 Chimaera, it is Green/Pink from otter switch all the way to the relays. Mine has 1 relay per fan in the fuse box.

Thanks guys.
I will have another look for a green/pink(faded white). Where would the easiest place be to pick this up? A picture would be good.
Where is this pin 17? Is it on the fuse/relay board?

I found the green/pink in the massive bundle of wires going up from the fusebox - from memory I think I may have dropped the fusebox down (Griffith) to find it and (badly) solder a wire onto it to feed across to the steering column, then via a switch to column earth. Once you have that big mess of cables, green/pink is in there, just needs a rummage around as mine was right in the centre of the bundle.

Thanks Andy.
I have now located the green and pink wire in an exposed section of the loom, behind the radio in a white multi point connector right up against the bulkhead. I have managed to ease it out hopefully far enough to get a piggy back connector onto it. It does start the radiator fans when earthed.

For future reference here it is the top wire in the photo:-

That clear/white connector is the one I was referring to.

Here's an article I wrote some years ago which might be of help to you....
