In post #106 I give the specific changes I made to get the top to go down with the key fob. MikeinAlexandria did the heavy lifting on the change but I needed one more change for it to work.
Coding is not hard but is a little scary and it can be frustrating when you think you have everything right but it still doesn't work. You need a cable I paid $99 for and some "free" software on a laptop and then you spend a few minutes downloading scripts from your car through the OBDII port onto the laptop, modifying them, and then reloading them. The scary part is you can mess up your car. So far I haven't however.
Getting the top to go down with the key fob is only one of many things you can do. I also like having the doors unlock themselves when I pull out the key, for instance.
