Does anyone have experience with ORS and/or Toyonlyswaps wiring harness for 3l to 3.4l swap?
I'm debating on buying one just for the easy convenience.
I know ORS is a little more spendy but is it worth the extra $? Thanks

 

Also you have to mail your engine/body harness into toyonlyswaps, do you have to do the same at ORS?
And do either come with wiring for re-routing the battery?

 

You should call them?

 

Not entirely sure on their new practices, but I didn't have to send ORS my whole harness when I got their kit. Just the engine harness to body harness plugs, if I recall. Also, I had to do the building of the cable for the battery relocation, but a length of cable was provided in my kit. Best suggestion is like Vasinvictor said, call or email them. Be sure to have some details on your vehicle on hand, I know they needed the vin of my vehicle and it made it easier for them if they have the vin of the donor vehicle, too.
