hey what's up? I was wondering if anyone could post a few websites or pictures of wiring diagrams of an 87 TII ECU. I'm trying to install an A/F guage and a trubo timer and I'm stuck, can't find oxygen senson wire. also if anyone could tell me a good way to get to my parking break wire that would be appreciated thanks.

 

lift up the console around the e-brake and there is a wire under attached to it.

as for you o2 wire. you can download the whole workshop manual from www.fc3s.org

 

I hooked my A/F ratio gauge under the hood at the O2 sensor wire and then ran it through the drivers side fire wall to the gauge. Easy that way.

 

Running to the ECU is just as easy as getting a wire through the firewall, plus tapping into the wire at the sensor very often ends up with the wire’s shield earthing the whole signal so nothing works.

Rex4x, read this thread, it’ll answer your question. Downloading the wiring diagrams from www.fc3s.org would also be a good idea.

 

thanks guys. even though I can't download the wiring diagram because my computer sucks and my abode acrobat seems to be down... hopefully I'll figure it out thnks again
