I have searched and can't find the answer.
How do I know if I have the Harmon Kardon? I don't see anything that says such anywhere, so I assume I don't?
Trying to upgrade the head unit, want to make sure I get the right wiring harness.
Thanks

 

not sure, but I have harmon kardon labeled all over my truck.....speakers and speaker screens etc....so guessing that is a sure way.....I would guess that you don't....but that is a guess

 

" I have harmon kardon labeled all over my truck"

 

I guess that's what I needed to hear then. I see no labels, so I think it's safe to assume non-harmon.
Thanks!
I don't know my model version (SE, LE or whatever) anyone know what I might have based on this?

 

I believe harmon kardon was standard equipment in HSE models only....

 

I just went through this over the weekend. Simplest way. Pull your stock head unit out. If it has rca cables going Into it then you have to buy the metra hatness for Harmon kardon. If it is just three plugs then the standard adapter will work.

 

My 2000 has the HK system (speakers are labled as such) but as far as I know, other than that, there were no other options fitted: no sunroofs, no ACE, no heated seats (but they are leather) I think the only sub-models in 2000 were base, SD, and SD-7.

 

"no heated seats (but they are leather)" then the heaters are there you just need the switches.

 

Yep. Did that years ago

 

I know this is an old thread but, I would also like to know if I have the HK system as well. The reason why I'm stumped is, Crutchfield says the HK system has two speakers in the front door with the tweeter in the A piller. I have that but no wording on the speaker grills.
Should I remove and look for the rca jacks?
