Do you have your 4th gen yet? If so, lay the two harnesses down side by side to get an idea of what you need to do. These cars aren’t Hondas that are built like Legos. Toyota isn’t making it easy for you. It’s far from a case of move this wire, bridge those wires, and done. You will be disassembling both harnesses, scouring wiring diagrams, and basically building a brand new harness from the ground up. Can it be done? Sure. But consider how many hours of labor you will have in just looking at the harnesses and figuring out what needs to be done, before you actually start doing any work. Time is money, and that’s more time that your car will be off the road. If you make one single mistake, you have to pull the harness back out (which is no easy task once the motor is in the car,) and start racing every single wire to find what went wrong.

I am not trying to discourage you at all. But it is definitely a much harder and more complex job than I get the feeling you think it may be. That’s why it is absolutely worth $500 to me personally to have Wiregap do the harness so it comes back extended to the correct length, all connections are correct, no loose or broken wires, plug and play with no issues. It’s one vital part of a swap that I don’t have to worry about. Again, not trying to discourage you- just my $0.02.
