2001 lexus is300 door l/ul

I need help for my IS300 door lock wiring,i followed with this diagram,however it is not working,i checked other forum said it need an extra relay and a diode for the installation.I connected with the alarm wire from blue and green to the wires below. LOCK MOTOR|GREEN/ YELLOW        |   |body ECU *1 | |     UNLOCK MOTOR|blue/black          |   |body ECU *1 |

     Power Unlock          GREEN/ BLACK          (-)          AT ECU ABOVE FUSEBOX                PowerLock          GREEN/ RED          (-)          AT ECU ABOVE FUSEBOX

Good lord on our version,  out comes the control box above the fuse box,  driver's KP,  remove board, cut the motor tracks, solder on two loops, bring them out through a hole then re-assemble, having drilled a hole in the box,  also leads coming in give you your door contacts,. Even putting in a phone kit was a PITA,  you had to run to a plug inside the trunk over the left side wheel arch to pull the factory mute!

Thank you,i will try it.

Hi I was wondering,that do i needed to add relay for the keyless control door lock and unlock?? Thanks
