ok i did wire it correctly but i first mistakenly wired the 0-5 v signal with 12 volt feed and i switched it back ( 12v wired to 5v signal car didnt start) when i switched it back to 5v signal it started fine . vacuum leaks i dont detect any but is there any other way to check vacuum and pin point vac problems ?

just make a "boost leak tester" you can search diy boost leak tester or here is a video i found real quick basically just attach it to your compressor pressurize your motor with a compressor and use a spray bottle with soapy water to source our leaks by spraying it over areas that could be leaking.
