HEY GUYS I'M WORKING ON A 89 VOLVO 740 GL AND I WAS WONDERING IF IT HAD AN OBD 1 PORT AND IF SO WHERE IT WOULD BE THANKS JAKE

 

I do not think 89 has diagonostic port. If it does it will be located on the drivers side fender up close to the brake master cylinder. It is a small plastic box with cover and has a wire that you can plug into various sockets.
