Well first thing first, I didn't like the fact that the homelink thing were on a small 12V battery and you have to take the whole thing down if you need to change the battery so i wire mine on to the car 12V and it work. :thmsup:

i got the homelink from Collegehillshonda.com (http://www.collegehillshonda.com/honda_accord_4dr_accessories/2008_accord_interior.htm)
they already did everything for you the homelink cost me 85 buck.

all i did is solder 2 wires to the end of the battery holder i didn't want to destroy the battery by cut it off so i just solder to the end of it.

at the other end of the two wires i just add solder to tint it keep all the wire intact and make it easier to poke in things :lmao:

well time to take down the dome light thing and poke that two wires somewhere :yes: i didn't want to cut any original wire and do anything crazy so i just poke in the back of one of the light harness

okay so it work :) now i don't have to worry about changing that battery ever again. :banana:

good diy :thmsup:

This is great as is the video by College Hills Honda.

But...doesn't the Homelink module come just as it is in the V6 with some type of plug connection? What does College Hills start with?...is it a Homelink part or a Honda part?


Thanks...Tom R

Does the homelink in the 8th gens have a security feature in which the kety has to be in the ignition to work? I know the ones in the Pilot's work w/o the key anf that's not a good thing.

Installed my '08 Homelink today...took about an hour...but most of that was "learning" curve :) I went with the 12V approach...dealer scared me away from tapping into the wiring...said they had a number of shorts that caused electronic damage...expensive and not covered under warranty.

Besides...by the time I got it all correct...I had taken it out a couple of times...and it is no problem...when the battery dies. Works fine.

P.S. First lesson...don't do in garage when freezing cold...NO I did not break and plastic parts...but I could have! TMR

Just a thought . . . for those that don't want to tap into the car's electrical system, why couldn't wiring for the battery be extended just enough so the battery could be tucked up in the sunglasses holder? I'm thinking it could be tucked up and taped to the forward edge (farthest from the windshield) where it would be out of site but still easily accessible.

Is it possible to just buy the homelink module that is offered in that trim and install it? Does it have a different overhead set up?

i wonder if, since you hooked it up to 12v, you can use the homelink when the car is off? or did you wire it up to a switched 12v source? b/c if it's constant, then you can use those buttons while the car and key is off!

do you happen to know how the homelink module is "hacked"?

i can get the module cheaper from my local dealership. but it will not have the college hills battery socket.

could i just buy the module from my dealer? and then run the wiring myself?

yes it is "hacked" in the sense that 2 low voltage wires are soldered from the internal circuit board to the battery socket.
others however have powered the unit directly to car's wiring harness (see Zeus' pic above).
since Collegehills has jcked up the price so much...diy/b(buy)iy option is good idea! :thmsup:
btw...how much is dealer asking just for the homelink module unit???

the circuit must have a third power input cable for the buttons illumination in the same way as the sunroof button lights up in the night. Has anyone done that?

Every homelink car I have had works with the car off. Its just like having a garage door / gate opener in your car.

i think the dealer is selling it for 100 or 110. something like that. im just not sure how CHH modded the circuit board to include the 12v battery. if i had a picture of where they attached the red and black wires i think i could definitely figure out how to DIY.

i cant find it at my dealer for 110.. best price i got was 150 about the same as CHH.. wonder how the OP got it for 85

Don't go through the dealer, just google "honda parts". You'll find plenty of online parts retailers that sell at a discount. Most sites sell the part for about $110.

Note that there are two Homelink modules though. The one for non-navi sells for about $110 and the one for navi sells for about $150 discounted.
