Hello everyone, I recently bought a 2004 Discovery S and decided that I'd like to have Homelink in it. I bought one of the older style off eBay that is supposed to plug into a connector in the ceiling above the rear view mirror.

I took the sunroof switch panel off and found a unused connector that was wrapped in foam tape and thought "Great! I have the connector!" I didn't bother taking the tape off...

Long story short, I don't have the right connector. What I have looks nothing like what I need. My question is, what is that connector, could I cut it off and put a new one on that would work? If that wouldn't work, what is the best way to go about getting power to the little Homelink thing. I don't have any issue wiring it into the fuse box, but some general instruction would be helpful.

 

Your truck is not sporting the ACE (Active Cornering Enhancment) system. That plug is for an accelerometer, to measure when you are trying to roll over da Rover. Here's page on it from the RAVE. Runs to the connector for the ACE ECU. Also on circuits diagram pages 64 and 65.

How to find stuff like this? Take the most unusual of the wire colors. Go to electrical library, connector list. Do a search for that color (like "OU," for Orange and Blue). Maybe there are 10 - 20 connectors out of all of them that have that color.

 

Aren't those three buttons under the front dome/map light in the upper center console the HomeLink that is already factory installed in the D2?

 

The three buttons he has in the third picture. Yes that's da home link. But it does not come in the s model...
Hey Alan does your mirror have three buttons on it? Some of the 03&04 models came with home link in mirror.

 

In your third picture it looks like you have the three homelink buttons.

 

I'm going to give him the benefit of the doubt and say that the homelink module in the third picture is the one he bought off of eBay.

 

Yes, that is the homelink box that I bought off eBay, it is there cause I didn't want to put the blank back. I do not have the homelink on my mirror, I know that that is how they came in 04, but I prefer the earlier style (that and it was cheaper).

Savannah, I had the thought that it was an ACE plug but didn't believe it. Your previous posts on using the electrical diagrams pointed me right to it though, should have accepted my research.

Where is the other end of that cable? Would it be possible to snip off both ends and hook it up so I can get 12v to the homelink? It's safe to say my truck will never have ACE.

My other option is to get a fuse tap from Autozone and run a wire up to the roof. Where would the ground be attached in that case?


Also, thanks for all the replies so far. Figured that y'all would be intrigued by a thread that didn't involve pre or post Head Gasket failure

 

See attached. Should terminate on pins 10, 5, and 6 of a connector under driver kick panel. However you wire it use an in-line fuse at the point you connect to power. Many vehicles, not just Rovers, are lost to wiring modifcation fires by guys adding a new GPS, boom box, inverter, two way radio, etc. Saved up for two weeks for the upgrade, took all weekend to get it installed, burnt truck to a deep fried crispy critter the next day.

 

Thanks Savannah! I think my best bet is to run a wire up to the homelink off of the ACE fuse with one of those "turn one fuse into two" plugs, or tap off the wires to the rearview mirror. That line is intended to power the homelink module in the mirror's with it built-in anyways. Seems like cutting those ACE wires and trying to re-do them is a recipe for disaster.

I'll post a few pictures of what I come up with for folks who stumble on this thread.

 

Well this is what I ended up doing, I spliced the power to the mirror and made a simple connector so that I can unplug the homelink in case (when) I need to take the headliner down. I added some pictures to clarify.

The wires I tapped was the green/white for +12v and the black for ground.
