I put one in my OBS 97, took 2 1/2 days to do it right and hide all the wires as if OEM. When I sold the truck I had one put in with an alarm diable system. Worth the price to have them do it , plus you get a warranty with the work. I have mine programed for a 15 second wait to start, and never had a problem with it not starting. Many good ones to chose from, some you can add heater mode or ac mode as well and rool the windows down or up. Good luck on your investment.
