Hi guys,

I have a KCE-865B to use with my Alpine CDE-9881RB head unit.

The headphone jack conenctor, I can see where that goes - into the jack in the back of the HU

But the 865B has black heatshrink with a blue and purple wire coming out, where do these go? They are bare wires with no terminations.

Also, there is a blue wire with the label 'remote turn on', where to put this? This wire also has a male bullet connector on it and a female bullet coming from the male??

Lastly, like the above, there's also an orange wire labelled 'Tel mute' which again has bullets on just the same as the blue wire.

I have no instructions.

Please help!

Dan

 

warning: I've never even seen a KCE-865B in real life! For some strange
reason that isn't going to stop me from diving in though.

Reverse engineering from the picture below (from eBay) it APPEARS to me that:

• the mystery blue wire is spliced to the +12v accessory power wire in the harness
  that plugs into the car
• the purple wire leads the dash switch wire in that harness
• the tel/mute wire probably is for connecting to the mute wire in that harness,
  but see caution below
• not sure what the remote turn-on ios for - normally it would be to turn on an
  external amplifier, but I would expect that to come from the headunit's harness, not
  the KCE-865B

CAUTION: I would not hook up the mute wire without knowing exactly what you're
doing - the dash control mute circuit can be blown by hooking it up the wrong way,
and a search of the Electronics Forum for "KCE-165" has a few posts that indicate
the mute may not be plug and play.
Anyway, hope this is of some use to you, and that someone who actually knows
what they are talking about will jump in.

 

Thanks, I have worked out where the bullet ocnenctors go from another forum, now I'm only left with the purple/blue wires from the black heatshrink.



When you say

"the mystery blue wire is spliced to the +12v accessory power wire in the harness
that plugs into the car
the purple wire leads the dash switch wire in that harness"

Which colour wire on the harness which plugs into the car and what does 'leads the dash switch mean?'

I totally agree the blue/purple must be the power wires to the 865B DCI but I just want to get them the right way round

Thanks again.

So if the blue wire goes to the red +ve accesory live feed then the purple must go to gorund (black)? That's the only place it could go right?

 

on the chart you have above, ACC is the +12v power wire, and is likely red.
the wire next to it, labeled "Remote" is the dash switch wire, and could be
almost any color (or even missing from the adapter harness) as it is unique
to the S2000 and many generic Honda harnesses don't have it.
this site has a chart with wire colors from the car's connector side which can
help you confirm you have the right ones.
Now I will throw in another possibility - that the blue wire is not spliced in with the
red alpine harness wire to the ACC circuit, but is instead going to the Remote wire,
and the purple wire is going to the Mute wire on the connector... unfortunately
the red and blue wires leading the the headunit connector are obscuring the view.
Where are the bullet connectors supposed to go?

 

As for ground, I've been troubled by the lack of ground, but technically
the dash switch wire (remote) is a ground, though one with variable
resistance depending on which switch is pushed.

 

On my harness (going to car) I have no pin where 'remote' should be??

 

that's a pretty common problem - if you have an unused wire, like an
extra dimmer wire - my memory is that the honda harness has a wire
for dimmer and one for illumination, but most aftermarket headunits only
have one - you can move it to the remote position. alternatively, if you have
no rear speakers you can move a speaker wire/pin to the remote position.

 

Good point!

 

so where are the bullet-connector wires supposed to go?
