Hey everyone I'm new here and new to riding really anyways I got a screaming deal on two f4is a '02 and a '05 one was not running and one was laid down anyways I did the whole swap and everything went great and when I turned the bike on it fired up which was a really good feeling anyways I had all the old harness plugs plugged in the headlights, taillights, etc. It would start everytime probably ten times I started it no problem. When I took the wrecked front fairing apart and put the headlights
on the new ferring plugged in the old tail harness with the led set up from the other bike no lights at all no start stop switch no fuel prime not doing much no time on the display with key off and when I turn it on the gauges work and everything but no lights on gauges at all not lights at all no fuel prime no start solenoid

I didnt pull the cables off the battery when I changed the front fairing and I plugged in to the wrong plug on accident could this cause a issue with the CPU or something I am stumped

 

Please help

 

Might sound obvious , but have you checked all your fuses?
