I was looking through the forums and I couldn't find a definitive answer.  I have a Z110BT in my car now.  If I replace it with a Z150BH will I have to rebuild my harness?  Or should it just be plug and play?

Thanks!

I don't think they have the same plugs.

Go to Pioneer's site, look up the two connectors for each unit and see if they have the same part numbers. 

Just in case anyone else was wondering - they are in fact not the same harness part number.

I did find someone else on the forum saying they went from a Z110 to a Z140 and all they had to do was redo the ebrake wire since it's on the other harness.  I'm wondering if going to the Z150 would be the same.
