well i have a b16 ist gen in my crx with two o2 sensors. i want to put a obd1 with aem computer. how can i hooked up the new o2 sensors with 4 wire. anybody please help. the conversion is 265 shipped. at http://locashracing.com/pages/harness.htm

 

You need to get the regular 4 wire O2 sensor (or a wideband since your using the EMS) and put in the header at the collector where most headers have a bung, and then put plugs into the two bungs that are left where the old O2 sensors were.

 

i understand i have to use a 4 wire, but i don't understand where the wire goes. one wire is ground one is heated and the other two is what lean and rich. please explain alittle bitter thanks for your time jhill

 

There are schematics available on line I am sure, and but the four different wires each are:

Sensor wire to ECU
Sensor ground to ECU
Heater positive 12v keyed
Heater ground

The AEM has the pin numbers in the instructions to wire to the ECU.

wait a couple weeks and I might be able to get you a conversion harness for $175. You're paying way to much
