I put the trailtech on my F2, but I can't get the front brake lever to actuate the brake light without the stock gauges. Does anyone that's made this change know what I need to do to fix this?

Thanks

 

Brake light circuit should operate without the cluster, but the cluster lights, turn signals, tail light (running light, not brake light,) license plate light and the brake light circuit is powered by the same fuse in the fusebox. Check that fuse, and check that you don't have any remaining stock connections that are shorted out causing that fuse to blow.

 

The fuse is good. My running lights work and the license plate light works. I did put a trailer integrator in to have integrated turn signals, so I'll check that wiring later in the week and see if that is the culprit. Everything else works, except the brake lights, without the stock cluster, and everything works perfectly with the cluster hooked up. Just to check: G/Y wire is brake, brown is running, and green is ground for the tail light, right?

 

At the stock rear light harness, yes those colors are correct. The 2 wires going into both front and rear brake switches, should be the G/Y and a Br/Black. The Br/Black is also the 12v power feed going into the switches, the G/Y then runs to the brake light. Closing either switch sends the juice from Br/Bl to G/Y and lights the stoplight.

The Br/Black basically comes off the fuse and sends that 12v power up to the cluster to illuminate 3 of the indicator bulbs (neutral,oil,sidestand), it also powers the coolant temp gauge (but not the light for the coolant gauge).

I can't find anything in the wiring diagram for the bike that would keep the switches from having 12V on the Br/BL wire without those connections in the cluster because there are distribution points in the harness where the Br/BL wire split to run toward both ends of the bike (according to the wiring diagram).

 

It sounds like the trailer integrator might be pulling signal or power from somewhere that is not powered up with the cluster disconnected.

 

Thanks for the in depth wiring description. I can easily identify circuits on the diagram, but haven't yet figured out a reliable way to find "+" and "-" in a particular circuit (except that green always seems to be ground). Once the wires go into a connector with several others it's like magic to me because I don't get to see the actual physical connection between wire and component.

My last final is this morning, so I'll be able to check on the integrator in a few hours. I suspect I mixed something up there because I was guessing at wiring colors and it just happened to work with the stock cluster. I'll post up when I take a look at it.

Also, I have a thread in General tech which these last few post seem more related to. Is there a way I can transfer the info so this thread is left more on topic?

 

Do you have your old cluster? I need a temp gauge haha

 

I do. But honestly it's not really worth having (and I'm reluctant to let it go before I get my current issue sorted). It was super jank when I bought the bike and I have only personally seen the speedo work. Hence the trailtech lol. However, I bought my vapor from a store on ebay and they threw together a custom kit with all the specific components used in the F2 set up so there was no guessing and no buying add-ons directly. The temp sensor not only tells you water temp in one mode, but also gives yellow/red indicators when you're overheating and critical temp.

 

Got a chance to look at the wiring and the integrator was hooked up correctly. However, I read somewhere around here that if any of the turn signals are unplugged then the other one on that side won't work either. Could this, in conjunction with the integrator, be the reason my brake isn't working without the cluster despite having it hooked up correctly? Is there a way to get around not having front turn signals on the front, and still close that circuit?

Update: Took the integrator out of the picture and the brake light works without the stock gauges. Must be a problem with the turn signal circuits. I've been lookin around here about that problem and I'll fiddle with it a little.

 

I have a 95 cbr f3 that I am looking to make this switch on. I would LOVE it if you could help me out with a link to that ebay seller or something.

Also I'd love to hear what you guys think about investment: I bought the bike for 1200, and I'm thinking of making it a streetfighter. Is it worth the investment? assuming I'm going to sell it probably in a year or 2. I would be buying new cluster (TT vapor), new streetfighter headlight, bar end mirrors. I'm thinkng thats all gonna run me about 250. I also need new tires, but thats more of a maintenance expense. What do you think, can I get 1500 back out of the bike or is that pushing it? got 28k on it, runs fine.

My other option is to just get some used plastics, and oem cluster and get it back to a used, original look. probably would end up spending the same amount of money
