I purchased a 2001 Alfa Romeo 147 with Euro Specs and plan to install a Viper 5704 Remote start/ Security System. Does anyone have the Wiring Information for this Vehicle.

Not alot of tech notes... put a 2000 as-well, though might be different.

Pretty straight forward, you'll need a 556U as a by-pass, standard Fiat/Alfa colours at the ignition, usual Fiat/Alfa white and blue low neg lock/unlock.
Fuse/body control box for window lifts indicators/ door triggers, diode block for trunk and hood inputs (not even sure there is a hood input though).
If it's anything like the GTV I did recently, engine bay access is a nightmare though.
Also beware all trim panels, they break.
Being Fiat 3 and 4 mm hex bolt keys required, also the steering wheel cowling will probably be a nightmare.
There might be a white loose plug in the centre console, that's where a POS Meta alarm is sometimes dealer installed.
Gives you lock, unlock, ignition, power and ground door triggers and indicators.
------------- Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.
