Hey Guys....I have a 2006 V6 that the engine conked out in. I picked up a 2009 motor to have thrown in there. I just got off the phone with the shop and he said that they got the replacement motor in and its running, it's just throwing a ton of codes. He said that since the motor is from a 2009 and my car is a 2006 the harness might be a little different, so they are going to try to swap those. I was under the impression that the harnesses are the same and if they weren't things wouldn't connect. I know they made some changes to the GT harness throughout the model years, but is that the case for the v6? Do I need to look at getting a replacement computer? He said he didn't even recognize some of the codes...this is a Mustang only shop...so I would think they know whats going on....any ideas?

Are there in fact any differences that would prevent a 2009 motor from being installed? The only thing I can think of is that the engine may have come from a manual and my car is an AT. Would this necessitate a harness swap though??

 

what are the codes? chances are if the harness physically plugs in, it is the same.

 

He said it threw a ton, I'll have to call back and ask for some of them so I can research...but he was knee deep in dyno issues. He had it fail and needed to finish 2 other cars today so I let him go. I'm just hoping I don't need to get a 2009 ECU and then get charged for that install & reprogram so my keys will work...

 

Spoke to the shop today and apparently swapping in my old harness resolved the issues....they will be finalizing the tune this week!!

 

nice!

 

Glad to hear!!
