Miata nb2 vvt swap to nb1 - useful info!

[rosspaine]

As I’m doing the same build 1.6 into one point I really appreciate it

hey im currently doing 1.8vvt swap in my 99 nb too! it has a blown 1.6.I got a question. Im using the stock 1.8vvt ECU and the wiring harness. But the 1.6 has only 1 o2 sensor, the 1.8vvt needs two. how do I wire in the second o2 sensor, since the engine harness does not have the connection plug for it, (I think its in the body/chassis harness).

Can you show the wiring up in your next video please?
