2005 BMW 325i And Viper 5901

I just can't see it on our tiny roads, though I've seen stretched Hummers! I liked the optional remote weapon system for the roof, eat that double parked taxi!

I tried finding the rear defroster wire today and I couldn't find it. I tested all the wires coming from the back of the climate control unit and had no luck. Any recommendations?

Use a DMM to find the wire that goes hot at the back window when you turn on the HRW, trace it to the front and relay it from the aux output you choose. It probably comes from the module behind the glove box but unless you can directly access this my method is faster.

Can i test it without the 556u installed yet and just put the key in the ignition

There is only 1 wire icant locate. Violet door trigger input. I cant find the RED / blue wire.

It's RED / blue and look where I told you ages ago to mount everything, in front of the OBD ll is a puddle or under dash courtesy lamp, there. Why don't you read the previous posts? How many times do we have to tell you? I've just noticed I told you before how to find the defrost Yes to trying the system with the key in the ignition.

I went to turn on my A/C and no air was coming out. Then I tried the Heat and that didn't work either. I didn't splice any wires so that couldn't be the problem. And I was in a rush and I didn't get to check the fuses yet. But if it isn't a fuse problem, what else could be causing this?

Does have this installed professionally ring any bells? Check your fuses, you've tested by applying power or ground without using a meter to TEST.

I finally got around to getting the spare plastic key. I am trying to install the 556uw but I have a question. Which wire do I need to splice into? There is a blk / YELLOW and a blk/grey wire. The grey one is giving me a 2.6 volt constant and the yellow one gives a 2.6 when u turn the key. I have a feeling. That I need to tie into the yellow one but I want to make sure.
