I have a trans. Temp gauge it should be here by the end of the week hopefully. I was wondering how they hook up. I thought i read somewhere where you have to drill and tap a 3/8 hole or something for the sender, i was wondering if there is a wire somewhere that i can tap into. Since i have a Trans Temp(which has came on before i got a new tranny) light i figured somewhere something is keeping track of the temperature and lights up to let me know somethings going on so i thought it would be easier to just tap into that wire instead of putting something in my pan ?

Also, I have a Air/Fuel Gauge coming with it and i heard that it just splices into the Oxygen Sensor and reads from there ?

 

I don't have one, but would assume you could tee in with the factory one. There have been several posts on this and where to hook them in. Inspection plug on trans. cut into line at the cooler behind the radiator. Do a search and should find some pics in the posts.

It would depend on wether it is a narrow or wide band sensor. Unless it cost $300. it is narrow and should connect in with the factory wires and see the same thing thetrucks computerdoes.

 

yes it is a narrow band sensor. I did a search and came up with nothing but ill look again. Thanks.

Also im looking to hook up a Vaccum Gauge(more of a Vaccum/Boost Gauge), i heard any vaccum line would work for this ?
