I installed the circuit today and it's a very worthwhile mod. I like the single-click mode where a single click on the driver or passenger window close
button will start the Auto-up on that window and a double click on the driver or passenger window close button will start the Auto-up on both windows.

Installation is very straight-forward but I did waste about 10 minutes trying to figure out how to do a blind install. I don't recommend the blind install to anyone except maybe those who have installed one of these the regular way and knows exactly where everything is underneath.

There is one minor detail I noticed. When starting auto-up; right after the single click, the window moves up a hair, pauses (maybe 1/4 second), then continues to go all the way up. Not really a big deal but I assume this is normal.

 

Yup, it's normal. Seems to be re-engaging the circuit. Did the same thing in my car, when I had an Ian Cull v7.

 

It is worth every penny in my opinion. I love auto-up one click and DSC defeat mode. Did the blind install and it went smoothly, you just have to feel around to know where the connector is and make sure you connect it properly.

 

Blind install can be done, just make sure it's "on target" and not one set of pins off.

 

I have this in both of our 03's and love them. My son's car is only used for double tap up on the windows but mine is setup for double tap, fog lights and DSC OFF. Great addition and well worth the money.
