Found some things in my engine bay... is my O2 sensor disconnected? Ground?...
Is this my O2 sensor wire thats unplugged?
http://webpages.charter.net/vtecpreludez/o2sensor.JPG I also found this ground, Its grounded on the engine next to the transmission, but its not connected to anything... anybody know where it goes?http://webpages.charter.net/vtecpreludez/ground.JPG |
I found out where the top ground went from searching, goes on the firewall (thanks aaroncake from previous post) But i found these wires on the coils with nothign connected... should i ground them?http://webpages.charter.net/vtecpreludez/cg1.JPG http://webpages.charter.net/vtecpreludez/cg2.JPG

anybody :(
|
The little black plugs are uinplugged on mine as well. I don't know for sure what they are, but it runs very well with them unplugged.
|
dont' ground those
the secondary one is used for an external tach hook up (setting idle) - they are used for testing. |

Originally posted by NZConvertible Why would you even consider grounding them? :confused: As a rule of them, don't ground anything unless you know it's actually a ground or you'll fry something. Those leads are where you plug in a diagnostic tach. |
What other wire?
|
What other wire? The one you think goes to the O2 Sensor? Or the one in the second picture?! There are two grounds...one to the firewall by the Wiper motor, and one to the top of the engine block under the intake Manifold. The one bolted to the block should be connected to the wiring harness...I could give you a better answer if I could see better...HUGE pictures...

First pic. That ground goes to a tab on the firewall. Part of the assembly that holds your brake booster line on. (IIRC)
|
It is the wire from your O2 sensor, at least, as best as guessed by the picture. Generally it connects to a connector that comes from the same general area as the BAC's. It commonly breaks off however :(
|
all we can really see is a black wire
if the o2 was replaced with a universal it might not even have the standard rx-7 connector on it. we would need some more info |

WOAH!!! I just finaly realised where the vac lines went stock. lol I never paid attention when I was ripping things apart. Too bad I already reworked it and ditched the ACV. That port on the intake piping had me confused for the longest time...
