good evening, I have been reading alot of posts on the net about doing a 1.8 corolla engine swap into my 2010 1.3yaris. I have a full 2012 corolla doner car, xd manual engine mounts, but the big question is the wiring. i have read people using a xd manual harness, are they a full plug and play or still need to modify the harness. I've seen in some countries they have a ts yaris 1.8 from factory. the xd manual harness from toyota is $2000. would the 1.8 factory ts harness be the way to go? I don't mind if I need to modify a harness, just need some info on the best way to go. any information be very much appreciated.

If you're running a Corolla ECU, you'll probably just want to use the Corolla harness and then splice the items you need over onto the Yaris Body connectors (CA1 and CA2). The ECU lines to the Engine and Trans would be more/less unmodified, however where the engine harness connects to the body would need to be modified.

I sourced this wiring chart from another post here on Yarisworld (please chime in if this is yours, I just can't remember which post). It breaks down all the connectors and which wires need to go where.
