ok here's the deal. i have a '93 civic DX (OBD-I) an HF manifold without an oxygen sensor and a 14B turbo with an oxygen sensor... stock, i have a 4-wire oxygen sensor and so is the one on the 14B turbo outlet... if i spliced it will it work? it should work, shouldn't it because they are the same 4-wire design... right? this way i can just fill the bung on the HF manifold and use it for an EGT probe later.

 

yes, and yes...

 

thank you very very much... do you know the specs of the bolt i will need to fill the hole in the HF manifold?

 

think its a 18mm thread, but i dont remember, i just usually take a dead O2 and hit it with a hammer then i have a free plug and i didnt have to go to a place that will charge you 5bucks for a bolt. BUT i wouldnt put one like that right above the turbo (or any O2 sensor) cuz you dont want it to break into peices and fall into the turbo...
