Ok here we go..... My friend and I did installed the VDI kit on my magnum on Friday. Total time was 6 hours. The first door took 4 hours to complete. The second door only took 1 hour and we were taking pictures of the procedure. Then it took us another hour to get the wire harness in a good position. The kit comes with instructions but i find that the picture are small and not as detailed as they should be. So this how-to is to be used along with the instruction booklet that come with the VDI kit. One a scale of 1-10 i would say this was about a 5 and i have never installed anything on a car besides simple things like a deck and amp. Just take your time with it. You will use the tools they have listed in the instruction booklet (locktite red, dremmel, 10mm and 13mm socket and extension, etc.)
