Acess automatic transmission wiring harness connector 2004 Mustang GT

Hey guys had a guy install 4.6 motor in 2004 Mustang GT.He got everything connected except the automatic transmission harness connector to the plug in on main harness on back of firewall...apparently he moved it back out of the way when engine was pulled out to build. With the motor back in there is no room to reach down and pull connector up to plug it in. Can anyone make any suggestions.....can't reach to find the plug and pull it forward to plug it in....Help! any tips appreciated.....This 4.6 totally fills the engine bay

There have been multiple times in my automotive adventures where found it necessary to "think outside the box". In this case the box is the view inside the engine bay.

Are you able to reach the connector from below the car? One trick I have used is to tape the connector in question to a long screw driver and push the connector through the tight space. I have used this trick with great success on the front O2 sensors connectors. Especially the one on the left side.

Another tick I have used is to grab the connector in question with a "bugger picker" grabbing tool.

Or a combination method. Tie a slip knot in a strong piece of string. Loop the slip knot around the connector from below. Use a grabber tool from above to catch the string. Once the string is above the engine level use the string to assist guiding it through the opening.

Speaking of thinking outside the box. I remember working for hours to replace an EGR tube on a Grand Marquis. It was just impossible to get to from above or below. After giving up for the day and sleeping on it, it hit me to try removing the wheel and fender liner. It was so easy it was almost stupid.

You may also get better results if you posted pictures of your engine bay. This will help us to visualize what you are seeing.

Good luck.

Thank you guys found the problem.....there are two receptacles that both have same pin pattern and design....my friend asked me if it was possible that the plug would fit both.....told him never seen it where they would interchange(usually a safeguard from plugging them in to the wrong circuit....he said lets try it.....we did and guess what they will.....anyway problem solved....
