Im doing an H23A1 to JDM H22A swap, everyone says the best decision is using my H23 harness and wiring in the VTEC and 2 pressure switches. Sounds good to me. So what i need is (detailed) instructions on how to wire them. Any help is much appreciated, thank you. BTW, I'm going to be using a USDM P13.
