on a manual car, I personally do not recomend a remote starter... and I wont install them due to insurance purposes... but if you want to, thats your choice and risk. You'll have to by-pass the clutch switch, that only allows the starter to turn when the clutch is pressed... I recomend using a on-off switch so when you get out of the car, you can activate it.

They really are not too hard to install... you can go to www.designtechintl.com and you'll find wirring diagrams with wire locations... which will make it 10 times easier to install. All the wirring is under the dash, and some models/brands use a power wire from the battery. I recomend finding a brand with external relays... the brands with internal relays tend to not work as well, and if a relay goes bad you have to change the whole unit, unless you are up to soldering in a new relay.

if you need more detail, let me know and i'll try to help further.
