So I've been shopping for tires for my '85 Brat, but I can't find any offroad tires for the factory 13" rims. Since I wanna put bigger rims on it, is there a good 5 or 6 lug conversion out there? And what possible offroad tires could I fit on 14 or 15 inch rims?

The only thing that I can see, is the harness goes into the cab on the left side, and that might be different for the right hand drive version.

I bought a 1985 Brat recently with the EA81 engine. When I got the car, I looked in the engine bay and found most of the wiring harness has been butchered. I may have done a bit of it, but we won't get into that . I was wondering if there's any website out there that would have a factory replacement harness?
