Here's what the catalog shows for the right mirror assembly for the
Accord: 76208-TA5-A11 008 001
MIRROR ASSY., R. (R1400) (R.C.)(HEATED)
CT EX-L: 76208-TP6-A21 008 001
MIRROR ASSY., R. DOOR (R.C.)(HEATED)(MEMORY)
CT EX: 76208-TP6-A11 008 001
MIRROR ASSY., R. DOOR (R.C.)(HEATED)
The mirror size for all 3 mirrors is R1400...
Xaque, I know you know how to interpret the part numbers what do you think?
Here is what I've learned about Honda part numbers:
(This was posted by someone else in reference to their motorcycle division, but it appears the same general rules apply)
he first 5 digits are the product class-all oil filters start with 15410, kickstarters 28300,etc. there may be minor variations here but this generally holds true.
Middle 3 numbers/letters are called the product code. this is the bike that the part was ORIGINALLY developed for. KZ3 is a CR250. KZ4 is CR125. CRF450 is MEB. Original CR125 elsinore is 360. You get the idea.
The final 3 digits/letters pertain to the version of the part and who they sorced it from when they have multiple suppliers of the same basic part. The first run of any given part is often "000", where as they will often update a part to make it better, and it's suffex will change to "001"
These are the cliff notes...
That all said... there isn't much that the part numbers are telling me (perhaps someone else can chime in).
Basically, unless part numbers are exactly the same, I never trust to decipher them. I've always been more of a "hands-on" type of person.
Remember, even though the Crosstour is based on the Accord, and shares much of the same items, it's isn't the same... they are two completely different cars and there are many differences (whether is be the size/geometry of components, or even just the materials used).
Here are my thoughts:
Step 1: Does the part fit? In this case, do the mirror mounting points match up?
This is the biggest hurdle for taking parts across product lines... the rest after this is all well within the modding realm... just a question of how involved you want to get.
Step 2: Are there electrical components? And if so, are there connectors? As a general rule, electrical components are often shared across product lines as much as possible to cut down on expense / complication.
If the part comes from the same generation, and the connectors are the same, it's more likely than not going to mate up fine.
(This goes for "simple" components, mirrors, lamps, etc... more complicated things that have a microprocessor component should be assumed to be non-compatible until proven otherwise.)
(And sometimes, even if the connectors are different, if it's a "simple" component, harnesses and connectors can be modded to work.)
If we have established that the mirrors in question will match up that's the first big hurdle.
As far as Step 2 goes, here is what I expect us to discover:
I'm expecting that the signal for a Fold-In or Turn Signal action wont being available at the mirror. As far as I know, the Crosstour wasn't designed to accomodate these functions, and thus, there wouldn't be any way for it to be activated at the mirror location.
Now, I could be *way* off here... perhaps Honda was anticipating these options in other markets and incorporated the function in the original design... but again, not knowing how Honda builds their cars, I wont know until I (or someone else) cracks that door open and sees what's coming through that mirror harness.
Beyond that, because I'm not expecting the functionality to be there in the vehicle harness, I'm anticipating that the harness plug will be different. Not a big problem, a little harness splicing and wiring isn't a *big* problem... but just one more thing that requires work.
But again, depending on how Honda designs its parts, there is a possibility that the harness plugs will be exactly the same... just without the extra pins/leads for the additional functionality.
Alright, so I've rambled a lot here... but here is the take-away.
I don't think we can be 100% sure until we can see the harness at the mirror, and the harness at the door (and onto that, someone probing the door harness to see what signals it is sending).
*But*
If the mirror mounts up fine... getting those turn lamp and park signals to the door is completely within the realm of possibility... I've wired up for more complicated actions in cars.
There... I hope that was clear.
All in all, I don't care about the folding mirrors... but hot damn do I want some of 'em turn signals!
