my car is similar in that i have more than one wire on my ignition to power different things. when i wired in my remote start, it said wire it to the brown wire. i had 3. i picked one at random and when the remote start starts the car all i have working is the gauges windows and heater. no wipers, heads up display, automatic lights or radio.
my best guess would be a) bad connection at the ign cylinder or b) if you follow the loom of wires down your steering column you will see them come to a big block with a bolt in the middle. sometimes that bolt will come loose allowing one of the connectors that slide into it fall out causing this problem exactly.
best of luck!
