I have the opportunity to get a D3 off Ebay for a good price. The catch is there are no cables or wire harness. I currently have a D2 installed. Can just swap the D3 in using the same harness from the D2?

my D2 broke and I just got me the D3 off ebay as well, i'm also curious what the answer to this question is...

If memory serves me correctly, it's not the same.

The D1 and D2 are identical, but I'm pretty sure the D3 is different.

thanks. the unit came with no harnesses. I was taking a chance that my current harnesses would plug right in. but the wiring must be the same right?

Yeah, the wiring connections are the same, but I'm pretty sure it has a different harness.

okay thanks. so my plan is to try and get harness then splice it.into the existing wiring. does that sound feasible?

Yeah, you could do that.

Okay. The D3 came today. I just tried to connect the D2 wiring but it didn't work. The speaker harness is the same, but the power harness is slightly different. Fortunately I found a harness on Ebay.
