Hi all- bought a V8 with no fobs 1 key and aftermarket Eureka immobiliser. i paid what can only be described as total monkey to remove this immobiliser and make the central locking and interior lights work again. They removed immobiliser but told me the c/l and interior lights wouldnt work still as someone in the past has wired them to work only when the ignition is live. (no good when you want to unlock the car and see what your doing in the dark befre starting the bloody thing!) Why he didnt resolve this is beyond me but seeing as he managed break the clips holding the binnacle in place, bugger up the light-switch and refit the stereo without seating it properly or plugging in the speakers, i thought best to cut my losses and not the tosser near it again!
The big trouble started though when i was driving along and hit a bump. The hazards came on and wouldnt go off.. Turns out the tosser had also left the green alarm ecu dangling and the bump caused it to swing and knock the side of the footwell. The only way to get the hazards to stop so i could continue my journey was to unplug the grey plug from the ECU whilst running, however whenever i come to re-start it, i have to lean over, plug this in first, start the engine and then lean over again to unplug it to stop the hazrds flashing!! it PAIN IN THE ARSE and stopping me enjoying my disco! Iv tried different ECUs but they wont even start the car (immob symbol appears on the dash). So does anyone have a wiring diagram or know how i can both bypass the ECU and get constant live to the CL and interior lights? Taking it back the auto electrician is NOT an option as i don't want that joker anywhere near it again!! Thanks in advance,

First you need to find what's happened to the original constant live supply the the security ecu, find that and reinstate it, you may then find your central locking working and interior lights illuminating when unlocking.

If they don't then to have central locking u will have to install a third party central locking ecu and a replacement master lock actuator

Interior lights are controlled by the multifunction unit from the signal from the door switches, if the don't U will have to find why not.
Fitting the ecu back on its mounting bracket should stop the crash sensor operating and activating the hazards.

If you decide to replace the security ecu with a second hand unit you will require the matching fob/s to enable u to remove the dash immobiliser symbol.

Thanks againDiscool- just realized i posted an almost identical thread earlier and you helped me then too! that was before i got an auto electrician involved though! Could i just run a live direct from the battery to the ecu and, if i were to do this- do you know which wire is supposed to be live on the ecu plugs- the haynes manual wiring diagrams are useless!

Yes you could or from the internal fuse box, can't help with the wire, I've yet to see a wiring diagram for the ecu possibly due to it being a security item. Have u checked the fuses for the ecu.?

no- am not sure which is the ecu fuse!

According to my owners handbook they are on the satellite fuse strip 1 & 2.
On the rear of the fuse box lid they are also listed, satellite1 fuses no. 1 & 5 and satellite2 fuse no.5 is central locking.
Fuses are also listed in the Haynes W/Manual.

Thanks again for your help! will try check em tomorrow- sorry for the sporadic replies- got a lot on me plate at the minute!
