Not sure if this is the right place to ask this question, I apologize if this is the wrong place.
My question is can I use my em1 power side mirrors harness (the plug that goes into the side of the mirrors) when I install ctr power folding mirrors?
thanks

 

yes, but you have to add a pin to use the folding function.

 

So does that mean the em1 harness only has 4 pins and i need to add a pin?
And is it simple to add a pin? I can't seem to find the ctr mirror harness for sale.
