after dropping in the motor i had this plug on the engine harness that didnt seem to have a home so after scratching my head a bit i decided to leave it to be done last thing. so it turns out its the plug for the purge control solonoid. i know the solonoid is on the intake mainfold and ive had a quick look but cant seem to locate it. can someone tel me exactly where it is please so i can see if someones taken it off before i got the motor its 99 b18c ITR
