depends on the remote starter you buy but most manufactures have websites with details and diagrams for your vehicle i know bulldog remote starters have a very nice website with most vehicles listed they also have a t- harness to help speed up the install,
but be warned i installed a remote start on my Nissan truck which i love, but the pit stop function is useless due to the key release button locking if the vechile does not shut off then the key is turned to the off position, I'm trying to find out how to bypass this safety feature but havent had much luck.
also its a good ideal to solder your wire connections instead of using crimp type connectors, crimp connectors work loose and can cause a poor connection and over heat or possible catch fire, but if you solder the wires you solve that issue,
i have fixed several remote starts that have burnt the wires due to poor connection
adjust your idle...the idle screw needs to be pulled left.
The posts that the calipers slide on need to be lubed too. Look at the brakes, something is touching the rotors. Something has been put together wrong or the slides are binding and the pads are staying in contact with the rotors after the brakes are released.
Check that the indicator needle has not bent over at the tip and is dragging on the dial. If it has you can apply a heat gun to the needle and straighten it - but it will eventually bend again - perhaps try gluing a sewing needle to the underside.
I empathize with you. There have been many times a customer came to me with a problem that I couldn't initially find. I always remember one simple rule: People rarely make this kind of stuff up.
