G60-NeedMoorePoower 0 Posted February 13, 2007 Hi I have a unknown GT alarm in my Corrado, GT part no's on the modules are GT 409, 431... Has anyone wiring / installation diagrams for these or any GT's that might apply ? {I am wanting to rip out this GT system and would like to do the job properly and have my Corrado actually start afterwards..} It seems I have a red (power) line going to the relay/fuse box... Thanks Jas Quote Share this post Link to post Share on other sites
