I'm trying to wire in a Reanult option Sigma alarm from a Megane Coupe and all i've managed to find on the subject so far is that Renault had a wiring code for non-factory fitted Cobra/Sigma alarms that was different to every other Cobra/Sigma alarm standard.

Why can't they just do things normally

hmmmm thats throws a spanner in the works will investigate further but thought they were a std fitment on the williams 1 can someone confirm definitely that it had no alarm fitted from the factory and was only an aftermarket option :D :D :D :D :D

You're more likely going to find answers by asking an alarm specialist. That's my next move and if it costs me £50 to get it fitted then so be it.
