Installing '10 GT alternator in '06 GT: How to connect? Please help

Hey guys, I would REALLY like your advice on the following:

I have an '06 Mustang GT and recently had to change out my alternator which had a bad diode. So after doing a lot research on the various forums I noticed a lot of people were recommending the alternator off the 2010 Mustang 4.6L. I understood that all you needed to do was ream out the O-ring that goes onto the alternator bolt and it would fit fine.

I got one off Rockauto however, but I can't for the life of me figure out how to get both the O-ring and the connector to plug in at the same time. Once you fix the O-Ring in place the connector wire is too short to fit, and if you twist it in a way that both fit, the alternator will not slide into place since the wire is at a weird angle that touches part of the engine when you try to slide it in place.

Has anyone done this same mod who can help clarify this? I have the stock alternator/battery wires. I am almost ready to call the whole thing off and get a shitty auto parts store alt :'(

 

Thanks for the response!
Sorry they're not the best pictures. The problem is the connector wire doesn't reach after bolting down the o-ring. Is it a matter of cutting the wiring cover to make it reach?

 

I appreciate the quick response!

Yeah I had seen that thread, although now I noticed a comment by JeremyH that reads "Then the pcm control connector on the new alt is in a slightly different location its same plug you just have to tweak the harness to make it reach. Very simple."

I guess that clarifies the nature of my question. How would I go about "tweaking the harness"?

 

Many thanks for the response!

Wow, would that be possible? That hadn't occurred to me at all.

 

Thanks a lot for the detailed response man! I appreciate the offer, but I'm based in LA. I'll have to mess around with it again tomorrow. Definitely will try un-taping the harness to see if that does it. I hope I don't damage the wires but I'll try to be careful. If you haven't noticed I am a total amateur! The alternator reclocking would be another interesting new project for me but hopefully I doesn't come to that.

 

Thanks for the tip! I'll give it a go

 

Hi Forty61, Thanks for the feedback! That's great hearing from someone who has actually done it. I had never heard about 'clocking' an alternator previously but it seems straight forward enough. Will try it this afternoon!

Hey Forty61, how did you manage to rotate the case? Did you have to remove the pulley?
I took the screws out and tried to rotate the back of the case counter clockwise 90 degrees, but it won't budge one bit, even with some light rubber hammer blows.

 

I removed the 4 long case bolts as pictured. Am I missing any other screws? Did you use a hammer or you could you just rotate it by hand? Thanks

 

I do have the OEM part... Right, I may have to try heat like msvela448 suggested. Worst case I'll have to remove the pulley. I just don't have the right tool for that...

Yeah, thanks for that video. It is helpful although my alternator is a little different from the one pictured. Of course the principle should be the same. So just to be sure, clocking an alternator won't do damage to any internal wiring? I just intend to rotate it counterclockwise 90 degrees.
