Not too bad. Made mounts and moved some stuff around and had to get creative with linkages and what not to mimic how it worked stock. As for 12v I just ran a new battery cable and put a 12v battery in it and a gauge reducer for the fuel gauge. Everything else is all 12 volts. I did build my own light harness and basically everything else too so I never “converted” to 12v.
What brackets did you make and what linkages did you have to move around?
