Updating wiring and speedo on a 03' Fe400

Hello all, I'm new to this site and husabergs, so sorry in advance if I do something wrong. (The signature thing is saying I've exceeded the max word limit of 0)

Just bought a 2003 Fe400 supermoto and it's pretty different from what I'm used to (85' Yamaha XT350). I've been looking to update it with a trailtech speedo/dash and to update the wiring harness to allow turn signals and the trailtech speedo, but that's where it gets a bit difficult. I guess they don't make many parts for the older bergs.

I'm curious as to how I can put on the trailtech and turn signals without completely tearing apart the wiring harness. I figured I could get a tusk dual sport lighting kit (or something like it) for a newer Fe390 or something and same for the trailtech and instead of splicing a ton of wires, I could just do a few going to the stator, since the new wiring harness and plugs for the trailtech should be compatible?

Anybody have any experience with adapting turn signals and a trailtech to an older berg? Is there an 'easy way'? Any help would be great!

Thanks :mrgreen:

I haven't really torn into the bike too much yet because of the poor weather, but it does have a headlight with hi/low, horn and starter button... There is a taillight, but there doesn't seem to be any wires coming from any of the braking components (front or back) and it doesn't come on when the bike is running, so I'm a bit confused about that... Is there supposed to be a banjo-bolt switch or something?

I'm pretty much a beginner as far as electrical work goes, so I'm just figuring things out as I go along

Are there any differences between the electrical outputs of the modern Husa's vs. the older ones? Wondering if the old alternator has enough juice to power one of the newer husa's harnesses with all the lights and stuff. The manual says mine is 12V 70+70W

I'm alright with splitting a few wires here and there, but I don't want to go too far into it.. I figured that If I buy a newer harness, with all the plugs and sockets for the turn signals, speedo, ect, but just splice the connection between the new harness and the old alternator and the ignition. That way, I could get the newer accessories like turn signals and the trailtech and just plug into the new harness and go.

I'll probably start with the new harness, figure that out, then go form there.

Thanks a bunch so far for your advice.

Alright, thanks guys. I'll take your advice and see what I can do. I'll try and post pics of the finished product if all goes well!

cheers
