    Wiring Harness

    I've been on the look out for a wiring harness for my xs400 and I've had no luck. The only place that I could find wanted nearly 300 dollars for it. Someone said do it myself however I'm not very inclined in electric work. Any suggestions?

    I am currently restoring a 1980 XS400 Special II model and I was wondering if the wire loom from a 1977 model is the same for the 1980? The one on the 1980 looks like it has been modified and I do not trust it. Can anyone clear this up for me please? Thanks!
