after unpluging my stock alarm i noticed my dash lights aren't working. also the wiper works on low and high but not intermitent. and rear defrost is not working either. i looked at the circuit diagram in the shop manual i have but can't make sense of it. i don't think i unplugged anything. does anybody know what those three things have in common? is it a bad relay?

 

those things all have in common: the time control unit

which also happens to be right behind the stock alarm
I bet you unplugged the wrong one

 

Yep, I'm willing to bet that is indeed the case. I just replaced my TCU due to the same problem. The TCU is a white plastic box which is piggybacked behind the Theft Warning Device.
