I have a bunch of wiring coming out of the firewall behind the washer fluid bottle and 1 Vacuum line, 4 were were routed behind the padding along the firewall and all of the plugs were not used, except for one that is plugged into a sensor on the oil filter housing. One of them is fairly large with 6 pins and with a big grey lock on it

Under the washer bottle I have 1 unused Vac Line and 2 unused plugs with some sort of metal braiding on them.

Just looking to know whats supposed to be there and what I can rip out.

 

seems like someone used some aftermarket gauges.

 

There was some before, I know that for sure. I also know Mazda likes to leave unused plugs all over the place too. My biggest concern is the one still connected to the oil filter housing.

 

seems like an oil temp sensor.

 

That is for oil temp, same thing my buddy has for his PS gauges. lol, buy some gauges, you already have the wiring done

 

Dude don't rip out... improve what they started. Sounds like maybe they took out an aftermarket oil catch can?? Is the oil psi gauge in the vehicle? Who sold it to you lol?

 

wish this wiring magically appeared in my car lol, Id order the $50 gauge and be a happy camper.

 

yeah just use the wiring to your advantage fine out what it was for n install the stuff if its all wired up for you already thats what i would do

 

The second pic is Oil sandwich adapter. for oil temp and/or oil pressure.

The first one yes.
