Please can someone tell me how the trinary switch system works on the 75 coolant fan? I have a 75 ECU now running on my Freelander 1 (I already got hill descent and traction control working), but the way a Freelander1 ECU controls its cooling fan is totally different. I think that the solution is to convert the Freelander 1 to the 75 trinary switch system but I don't really understand how they work. It has air conditioning so I'll have to do that the 75 way as well.

anyone know of a breakers that specialises in 75s ? I'm after a torque converter but it needs to be from a 1.8 K series auto.

I spent much of today crouched here:- with the engine dangling above my head. Drilling out spot welds:- and peeling back metal. This bit fought me a bit:- I'm nearly ready to start making a replacement bit and start welding it in:-

I love my Jag XJ 2.7 diesel. It's really quick and yet can do 50mpg on a run with just a little restraint. It's supremely comfortable and has all the toys. It can tow a two ton trailer. However I don't think it complies with "peak" car because if one ECU fails, or the battery is a bit weak then all the electronics go nuts, and it's not ULEZ compliant so it' rapidly becoming an ornament instead of a car. For me peak car has electronics, because toys like cruise control, but they should remain discrete and having one fail shouldn't kill the whole car. My 1996 Passat was like that and so was the 2000 806. The smaller Rovers (25/45) were also like that and the last ones are ULEZ compliant so maybe peak car is a Rover 45 unless the last of the last Peugeot 406 was ULEZ compliant.

There is a 604 for sale in Doncaster at the moment:- https://www.ebay.co.uk/itm/255673376731

Not sure if this is the right place to leave this:- https://www.ebay.co.uk/itm/255673376731
