I just installed a commando in my f250 -- it was a little tricky with all the wires -- but it wasn't to bad if you took your time.

If anyone is looking for a low priced alternative to Viper, I carry www.Ultrastarters.com The commando is a remarketed unit sold under many different names. I have a few in stock but do not suggest them unless low price is the most important factor in your purchase decision. Though for the prices posted at commando.com you could purchase the real thing for less as long as you mention it is a OSO member deal when you email or call me.
