I've been researching this problem for the last 2 days all over the internet using multiple search engines and I've been coming up empty handed. I have a 97 HX d16y5 as of right now but tomorrow I'll be buying a full(minus the harness) b16a2 swap. So far I've determined that it will be a straight forward install but I'm having trouble finding how to wire the 7/5 wire primary O2 sensor to the 4 wire plug. Since i want to use a obd2a to obd2b conversion harness fothe P2T All I've found online are people dropping from obd2a to obd1 or they switch the harness to EX. All of the closest threads sent me to eastcoasthondas.com which is no longer hosted. This is my first swap, but i chose the b16a2 for its simpler install. I know i need to run a knock sensor, and IACV. I also heard that the HX does have a sensor that won't throw code 91 and other sites say it doesn't. So to the point....
1) Is it possible to use my HX harness for this swap considering the primary O2 is 5 wires?
2) I live in NY, so i wanted to put the P2t ECU into it but it seems everyone goes P30 down to OBD1? What route should I go?
