Just looking for clarification on this, so hopefully someone can give me a quick answer, as searching hasn't proven to give me exactly what I'm looking for.

If I am reusing my stock 1ZZ wiring harness for swapping in a 2ZZ, can I still use the MWR PNP swap harness adapter, or does that only have applicability with a 2ZZ wiring harness?

Thanks in advance.

The swap harness allows you to use the 1ZZ harness without the hassle of repinning the plugs on it. It also adds the two wire that are required for lift. DDP has them for $325 or MWR sells them for $350. A lot of money but it makes the swap easier.

Yes, our harness is a simple plug-in between a stock 2zz Celica ECU or a 2zz PFC and your 1zz wiring harness. The additional VVL connectors needed are part of the pnp harness. The only other thing you need to do is switch a couple of pins at the TPS (they don't go to teh ECU so no way to fix that with the harness)
