Like the title says...anyone ever installed one? Id like to put one in my car in the early spring. Although I've always done work on my own cars this one kinda has me a little nervous..most of the anxiety is coming from a wiring standpoint.are the instructions very clear and precise? How hard was it?how long did it take from start to finish? Did u have any problems missing parts of the kit? Sorry,I know its alot. The plumbing part of it doesn't seem too bad as I've done that kind of stuff before...the wiring on the other hand...im not so sure of. Any experiences or comments are welcome..thanks in advance.
