overcamp67 Posted September 6, 2017 Share Posted September 6, 2017 Hello everyone. I'm new here and fairly new to Land Rovers! After two years of owning a 30 year old 90 300TDi, I've traded it up for an '03 plate TD5 90. I'm looking to make it a wee bit more secure etc! I've a brand new - un-fitted Toad Sterling Touch Cat 2 immobiliser which would make sense fitting. I've been over the installation instructions but looking for any member advice before I go cutting and soldering wires. I've attached a couple of screen grabs from their instructions however can anyone point me towards the best wires/connections to use and their best location. It is the connecting of the BLUE and WHITE wires I'm unsure of: BLUE - 'starter motor isolating circuit [18a relay used for this circuit]. WHITE - 2nd isolating circuit [18a relay used for this circuit] This circuit must be live during cranking and engine running. Any advice greatly appreciated. Thanks, Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted September 6, 2017 Share Posted September 6, 2017 A lot of insurance companies won't accept DIY fitted alarms, should that be a concern. Quote Link to comment Share on other sites More sharing options...
V8 Freak Posted September 6, 2017 Share Posted September 6, 2017 Hi and Welcome to the forum... Blue wire.... The relay for the starter is in the main fuse box in front of the gear lever... The feed wire is orange & black (Relay is usually 2nd from the left) White Wire.... There will be a wire on the key barrel that remains live for cranking... Can't remember the wire colour off hand but I'm sure a grown-up will be along to advise. (Try looking for a white / brown and testing with a meter....) Hope this helps....

I'm guessing I would 'cut' into the starter relay wire as it goes into the relay? The immobiliser will prevent the relay from triggering the starter - yes/no?

Good point. Currently down us 'none/factory fit' so should be OK and insurance was granted OK. Will probably have to keep it as that status, not mentioning the immobiliser, but it's there for my own piece of mind. Quote Link to comment Share on other sites More sharing options...

I recently converted my Td5 Defender to auto and I cut the orange / black wire, fitted connectors (So I could re-connect quickly if needed) and that relay / connection is now controlled by the Compushift ECU... If not in Park or Neutral the ECU won't power the relay and therefore won't let the car crank. I'm assuming this is what your alarm will be doing too...
