I did not connect two wires. The trunk pin wire and the flashing lights wire because I did not have time. I will, however, next time when I connect the DEI 530T (window roll up/down module). These are the sources that I used which were very helpful:
I finished the job in about 12 hours over 3 days, mainly because I was testing the wires to make sure they were the wires I wanted. The project is doable for any average joe that has patience and wants to ensure that a good job is done on their cars.
If you have any questions please feel free to post or PM. I will reply as soon as I can. Good luck with your project and stayed tuned for additional DIYs.
