2003 Volkswagon Jetta Wagon 2.0 won't start; someone helping me jump start the battery had the cables on his end switched.  I replaced the ECU and the dash board lights up, but won't start.
Can someone reference me to relays: 175, 100, 53, and 409?  I guessing to start there and watched a couple of youtube videos on relay 109 which I can't seam to find under my dash.

if you changed the ecu out for another one you likely have not programed it for the car.. put the old one back in cause usually jumping the car would not have ruined your computer unless he attached the jumpers directly to the board.
