03 Hyundai Elantra Tach And Power Lock

I just installed a remote start with power locks in my buddys wifes 03 hyundai elantra 

i didnt use the Tach wire because the wire spec sheet i had DIDNT specify where the ECM was. i used the voltage sense, i hate doing that.I wanted to know if anyone can tell me any info on where the ECM is in that car, as well as color, pin or anything else would be awsome.also, i havent attempted it yet, but the remote start also has the ability to activate power locks, however the car does not have a lock/unlock button, its more like central locking, unlock the driver door, and the other doors unlock.. And in addition the diagram i have did not even specify locations or colors for the power lock/unlock on that car.

any help is greatly appreciated.

If you searched this site you could have answered your own question... https://www.the12volt.com/installbay/forum_posts.asp~TID~5330The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.

Do it right the first time... or I might have to fix it for ya
