i did mine myself....its really not that hard...its just a matter of remembering where things go...no 2 harnesses are alike...so u really wont have to worry about that...theres really not as much involved as everyone thinks there is...its maybe 2 hours worth of work and a pretty easy project...just make urself a diagram on where things go...take everything out off of the dash u can while its installed ex: gloveboc, airbag, gauge bezel and gauges, climate control, vents, radio, and ur clock...and it will reveal all the bolts that are needed.
Trust me when is say its not that hard...and if u have any problems with it PM me and ill be glad to help you out
