i put in my apexi turbo timer a while ago and didnt hook up the wire for the o2 sensor to show the voltage and estimated a/f ratio....but now i wanna hook it up and dont know which wire to splice into on the o2 sensor. theres four wires comin off the 02 sensor itself, do i splice into those? or an ecu wire....someone help. i have a 96 talon esi, hrc stage 2 :9. also....where the hell is my ecu???? hidden like no other. it says it's in the dash but i cant find it. maybe pickybacking the fuse box by the pedals? one more thing....does anyone else think hahn's downpipe idea for their turbosystems is retarded....cut my downpipe and use a clamp? g.h.e.t.t.o

props to the star kit's downpipes

Your ecu is in the engine bay. Behind the fuse box. Silver with ridges. Crap load of wires going into it.

You're gonna need to splice into the ecu, not the o2 sensor I believe. As to what wire, I cant remember, I would use the search fuction.

u sure? sounds good to me..it actually makes it easier, now i just need to know which wire it is

anyone have a 96 eclipse/talon ecu pinout? wiring diagram perhaps

its white with a black stripe. you should be able to find it in the top section of wires. a search or the shop manual should show you exactly what pin.

thanks guys, super helpful
