Shouldn't be too hard...I put one on my '97 GL, just follow the video and read all instructions. It just consists mostly of hooking up a power wire ,the starter wire and a ground.
Although you might have a problem with the PATS. I didn't have one, you might want to check with someone like a best buy installer, and ask him about it.
I have put remote starts on my 2000 SE, as well as a 2003 and a 2004 Ranger and a 2006 Odyssey van. All have been Audiovox units and have never had trouble with any of them. Last one I had installed was on the 2003 and paid $180 including tax out the door. Unless you have considerable auto experience, I'd suggest having someone experienced do it.
Im going to install a prostart in my 2001 taurus shortly
i have installed one in a older temple and worked fine but these cars need a pats key so we will need a transponder switch to override the key during
remote start. I have perchased online from ebay an expresskit bypass modual which will bypass the key temperarily to operate the starter.AS im not sure how to paste a short cut here i can only tell you go to ebay and serch for a ford taurus transponder this one is only about 10 bucks out of quebec canada.I havent got it yet but will be installing probably next weekend or following week.
before i start im trying to find out if i need a relay to operate a second ignition wire or anything else as i havent looked at the wires yet.
There is some good wiring diagrams on this sight to help if you serche for car starters.
you should have a good idea how to use a volt meter and general knowledge of electical wiring but isnt impossible if you are a do it your selfer.
