Hello all.Can anybody point me to the right location of the yellow junction box where the black/white striped power wires join up.I have removed the entire air intake setup with no joy.Under the headlamp unit I found a yellow box…terminus ,but it was full of green wires ! There is a photo from Ian in South Africa dated Oct 11,2021 showing the item.Mine is an 08 model so it may differ from earlier models. I am chasing a lack of continiuity between the black/white striped power wire exiting the engine cut out relay/ bank relay and the fuel cut out relay Thanks.
Yellow junction box
- Thread starter richie
- Start date
It's under the PAIR solenoid which, according to the blurb, you'll need to remove...
There's 2 Joint Connectors located there, a Pink Ground Connector and the Yellow Power Connector wrapped up in tape.

@canada_67 - I've never come across it when I have been fiddling around under the fairing- so I have just been looking through some photos with the airbox off - is it / are they - that taped up block on the lower right of this picture ? down and right of the open brass tube connector on the PAIR solenid ? Photo taken looking under the airbox from the left hand side of the bike.
John, yes, the PAIR solenoid is on the right of your photo which can be removed to get better access, the Joint Connectors are wrapped up below...
Be careful with that box cutter (USA) / Stanley knife (UK)!!
Useful photo by the way!!

I never even noticed it when I had the PAIR solenoid disconnected - and I don't think I've ever seen a photo with it identified like that.
I've seen a multi-way yellow connector somewhere behind the headlamp fairing / screen adjuster and I thought - so that is where it is. Except it had the wrong colour wires going into it. So all that told me is that there are two yellow connectors.
I don't need the info right now - but it will sure be stored away for future reference. And @richie will find it useful.
Many thanks for the info - and for the red circle ?

Thanks very much.At last some direction....now hoping to find cause of loss of continuity ! Will report back.
I will be looking in there asap.many thanks for your feedback.
Watching problem your chasing same failure my bike did
Back again...found the yellow box where it was indicated to be.Upon freeing it out and prising the cap off it,sure enough signs of excess heat on the terminalwhich turned out to be the feed wire from the engine cut out relay...Bank angle relay. I cleaned it up and applied dielectric grease all over. Continuity back to both black wires into fuel pump relay...yay.After replacing airbox and tank into position i tried starting it. It was reluctant to start but was firing.It did start to run smoothly for 30 seconds or so,then started to miss and stopped.A quick check and no more power into the fuel cut off relay.Any thoughts on why that particular wire terminus should have "cooked" originally ? Honda certainly didnt seem to want that part tinkered with. The fuel pump can still be made to whirr with a live feed through its switch block.Appreciate any thoughts,thanks.
Excess heat on a termination can anneal the connector, lessening the spring tension. Dielectric grease is an Insulator! When spread on connectors, the mechanical action of pushing the two halves together (and the spring tension) scrapes the metal pieces clean and you get metal to metal contact. If the connector does not scrape the grease off as it is pushed together, you will have a bad electrical connection.
I'm not saying this is the problem, but it might be. It is better practice to clean the connector halves with a spray contact cleaner, push them together, and then smear your dielectric grease around the now mated connector.
Connectors get hot when they get some corrosion. That increases the resistance to current flow which produces heat. It seems to be a more common issue with higher current circuits normally e.g. alternator plugs on my VFR800, and the 30A main fuse connections seem to have similar issues.
Cut connector off join wires together with a crimp band. Or try to solder them together
My bypass repair I did working fine road it yesterday again 1200 mi since repair.I probably will get to that connector and cut it off join wires together some day when doing maintenance next summer
Got 169000 mi on mine original owner All work @ miles by me!
