yourekiddingright Posted February 22, 2017 Share Posted February 22, 2017 Hi all, Can't seem to find a recent enough thread on this to know what's possible.... I have a 97 defender 300tdi with a TD5 binnacle (and gauges) and was wondering what's possible regards fitting a cruise control kit - before I delve into the world of after market kits I wanted to know for sure that I couldn't make a cruise control kit from a TD5 work? Am I right in thinking that it relies on an ECU or can it be made to work without? cheers Quote Link to comment Share on other sites More sharing options...
crwoody Posted February 22, 2017 Share Posted February 22, 2017 Cruise control on a Td5 is entirely integral to the engine ECU with it's electronically controlled fuel injection. So far as I know the 300tdi is purely a mechanical injection pump system, so I'm afraid you'll be out of luck on the Td5 route. 1 Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted February 22, 2017 Share Posted February 22, 2017 You'll need a Waeco kit to run on a 300 Tdi. Retroanaconda on here has one on his 200 Tdi. HTH Mo 1 Quote Link to comment Share on other sites More sharing options...
yourekiddingright Posted February 22, 2017 Author Share Posted February 22, 2017 Nice one ta - just found his/her fitting guide. Does anyone know how/if I could reliably use carling switches instead of the switch that comes with the aftermarket kit? An off / on and a momentary (speed increase and set) / off / momentary (speed decrease and resume) for example Quote Link to comment Share on other sites More sharing options...
Arjan Posted February 22, 2017 Share Posted February 22, 2017 (edited) I had a VDO Tempomat in the RRC with the Mazda. Not cheap but very, very good. Interested to hear about the " Waeco kit " as I again will need to fit one to a 300 Tdi.. Tdi needs something with a cable to move the lever on the pump.

yourekiddingright Posted February 22, 2017 Author Share Posted February 22, 2017 Just found another kit called the AP500 which is a mechanical cable servo http://www.bridgwater-electronics.co.uk/cruise-control-kits/c51 £270 including Vat, delivery and CM35 stalk 1 Quote Link to comment Share on other sites More sharing options...
yourekiddingright Posted February 22, 2017 Author Share Posted February 22, 2017 (edited) Chap at bridgwater seemed well informed when I enquired about defenders. Regards using carling switches instead of stalks he told me: "The AP500 system has the ability to 'learn' different switches if they are resistive. If the switches have 1 wire per switch, it may not be possible. If you decided to use another switch, we recommend that you purchase a CM35, set the system up and test it using the CM35 and then try the other control. If all is well, return the CM35 to us for a credit. It is possible to use individual switches but you would probably need additional electronics to interface with the AP500 control unit". Any electronic pros fancy explaining how that might work? Edited February 22, 2017 by yourekiddingright Quote Link to comment Share on other sites More sharing options...
