Help!!! I have an extra wire! difference in clali harness?

Help!!! I have an extra wire! California vs. 49 state harness?

I am in the process of re placing my wire harness on this new years eve. as I have been making the conections I have found that I have a wire and plug on the new harness that does not exist on my old 49 state burnt up harness. The harness that I am replacing it with is off of a cali bike. My question is... are the harnesses interchangeable other than the extra plug that I could tape off?

 

What does this plug go to ???

 

here is another pic of the wire and plug in question

 

Steven just out of curiosity,how many wires are in that plug connector and what are the wire colors?
Info like that might be a little more helpful in solving this riddle.

 

It turns out this is a california bike harness therfore having this extra connecter. wire colors are Bl/w and Y/Bl. wireing diagram shows them terminating at "intake duct control solenoid valve" wich I assume is something to do with cali emissions. I finished conecting the harness up last night and left the plug hanging loose and hoped for the best. The bike started and runs without any problems or codes so I plan to just zip tie the connecter out of the way somewhere. It would seem that the cali bikes have a slightly different harness but can be used on a 49 state bike but a cali bike could not use a 49 state harness.

 

That is a very important detail that may come in very handy to someone someday. Can you fix the typo in the title of your thread in case someone out there is searching for this later?

Thanks for posting the followup to the problem, so many times I see someone figure a problem out, but run out of steam on posting the results at the end.

 

I would love to change the typo but I cant figure out how to... Let me know if you know of a way to do this.

 

Ditto on that! There have been some intriguing problem threads that just disappear. It always feels like somebody told you about electricity, but never told you about light bulbs...

Steven on my 6th gen. the "intake duct control solenoid valve" is the electronic control solenoid valve that allows vacuum pressure to operate the flapper doorway mounted on top of the airbox. On my 6th gen. it's located on the right front side of the airbox between the airbox and the frame rail.
I checked the Honda parts fische,your 5th gen. has this exact same solenoid valve on it. Here's a pic of the solenoid valve mounting location on my 6th gen. with the airbox cover removed.


Here's a better view of the solenoid valve mounting location with the whole airbox removed.


Here's a pic of the plug connector on my bike. The wire colors are Black/White and Yellow/Black,same as on your bike.


Remove your seat,unbolt the tank,and lift it up. See if the solenoid valve is located on the right side of your airbox,and if you have any wire connector plugged in there. Let me know what you find.

 

I have the same plug on my 5th gen with the same wire combination wich is the same colors as the wire in question but the plug the goes to the air box there is part of the secondary harness attached to the throtle body and plugs in to the large harness plug to the primary harness. For some reason the cali harness has another conecter with the same wire code that must attach to an additional sensor. Here are some pics of two different throttle bodies I have in the shed. The one with the airbox attached is off of a Cali motor and the one without the box is from a 49 state bike. both have the same conecter to the airbox that is in your photos and both of them come from the secondary harness. The extra plug from the cali harness I just put on my bike must go to something else. Being that the wire code is the same I would guess it is somehow linked.




The first 2 pictures show the same plug end you describe in your pics and the second 2 pics show where they terminate into the large connecter on bothe the cali and 49 state throttle bodies. Another thing I will mention is that I dont see anyware on the cali throtle body that the plug in question would fit so its placement seems to be seperatly mounted somewhere else.

 

Okay Steven thanks for that info. I've got one more possible location for you to check,then I'll declare myself officially stumped. On my 6th gen. the EVAP Canister Purge Control solenoid valve connector plug has the same Black/White and Yellow/Black wire color combination. Here's a pic of the plug connector,you can see where it comes out of the clear wire harness boot.


Here's a pic of the EVAP Canister Purge Control solenoid valve. It's bolted to the right side frame rail on my 6th gen. In the pic above this one the solenoid valve has been removed and there are Orange and Green bolts plugging the bolt holes. Do you have this solenoid valve plugged in on your bike? If so then I'd definitely have to agree with you that there must be something extra on the Cali bikes. Sorry Steven,I took my best shot.

 

That is it! That is where the wire comes out at the cali harness also. Only on a 98 49 state 5th gen that wire, connecter and sensor are not there but it is on on the cali model. Now we know what it goes to does anyone know what it does?

 

The 6th gen. bikes are equipped with an EVAP Canister Steven. It's used for emissions. It collects fuel vapors from the gas tank and stores them so they don't release into the atmosphere. After the bike is up to operating temperature the solenoid valve opens and the fumes from the EVAP Canister are allowed to pass into the intake tract to be burnt.
What's really odd here is that the 5th gen. VFR800 Honda parts fische lists the EVAP Canister for your bike,and yet it makes no mention at all that it's supposed to be any kind of special equipment for the Cali bikes only. Did you buy your bike used Steven? Maybe the previous owner simply removed the EVAP system and cut the extra wiring off?:noidea:
I dunno,you're gonna have to get a couple of other 5th gen. owners to chime in and help you out on that one Steven.

I removed my EVAP system. In SJC's "Help with de-pairing" thread,CandyRedRC46 was right when he said that the EVAP Canister was basically just there to make oil filter changes a bitch and it's just a couple extra pounds of dead weight on the bike. Here's what the EVAP system looks like on the bike Steven.


And off the bike.

 

I bought the bike used but the bike was very low milage (6k) and unmolested. It had been wrecked in 2000 and sat damaged in a shed until I bought it as a project about 2 years ago. The bike had a catastophic engine failure before I got it registered last year so I repowered it with another low milage 49 state 1998 motor. Neither the original motor or the replacement motor have the evap canister. This last summer I came across a realy good deal on a spare motor for a 98 with low mileage for a price that I did not want to pass on. When I got the motor home I noticed it had the evap canister and that led me to find out that it was a california motor. The 49 state 5th gens(at least 98 models) did not come equiped with that canister. Infact, the bracket that holds the canister is a different part number and does not have the supporting rod but is still there for a point to mount the lower fairing.here is a pic of the 98 cali motor with the evap canister.

 

Cool! That's all good info to know.
Looks like Honda's getting a little lazy with the info in their parts fisches.
