Need a new Ecu Harness

[Kundo240]

I want to rebuild my ka24e motor, but I know my harness is not in the best condition and it would cause and injector to go dead and then come back everytime it would be moved, so I want to take it to get serviced so when I put in the motor I don't have to worry about that, does anybody know any place that would be able to help me, thanks I appreciate it....
