I have an 89 crx si "OBD0" running a 4 wire O2 sensor. Wired up the power and ground, but the white wire I connected to the O2 signal wire that goes to the ecu. When I start it up drive it and all, only the first light comes on. I checked the halmeter online pdf install guide and it gives 3 diff install instructions. Also in the troubleshooting it says I might have a faulty O2 but I'm using an O2 from a 2000 Si. Well here's the online pdf file, help me out!

 

wh00ps, forgot to post the url for the pdf file.
