I think if u use the ep3 harness it can turn on but Ill rather kpro anyways since it will be a lot better for u car

You need to use the ep3 wiring harness and K-pro, you can't use the z1 harness or ecu. You can't use the stock ep ecu either until it is kpro'd.

The Z1 harness will not work with a EP3 ECU or even a typeS ECU without a special adaptor harness, a VSS convertor, AND a specially modified typeS ECU with Kpro that can not be reconfigured.
