just got my supercharger put in, and i wanted to add some gauges with it i already ran the boost and it working great, I am now running oil pressure wich that one i figure just have to "T" it off not a problem but if any one has done it i would like some advise on how they did it with SC in the DAM way lol! then the 3rd one im having most problem finding any one that done it or how they did is the AIR/FUEL ratio gauge im installing on and i did this before on my celica i just taped into stock sensor worked fine i was thinking about doing the same but there 4 wires and the gause said on the box hooking to wrong wire can cause gauge to break and they wont cover it =( so anyone know witch color is the signal wire we got 2 blacks one white and one BLUE, i think it blue but not yet tryed it =)

thanks
typed realy fast sorry for bad grammer is any had to go somewhere

 

WOW, 49 people look at this and no one know what wire, so this mean no one has ever installed a air/fuel ratio gauge in a tC yet WOW!!! or just to lazy to post come on guys help me out a little, at least tell me the wrong wire so ill just go try it and tell you i messed up so you will know what wire HAHAHA

 

Thats because the cheap a/f gauges will not work in the tC. The tC has wideband sensors and your gauge will not work. You need a Wideband z/f gauge in order to read your afr's. The best place for the oil pressure gauge would prooly be with a oil block adaptor since the s/c is in the way.

the 49 people who viewed were prolly tired of answering the question over and over. The search button is your friend.

hey thanks man! good info, but i seen this a/f gauge installed on many other stock sensors by taping into the sending wire, what stops the sending wire on the TC not to work it looks the same? sorry if it dumb question but you seem to know this stuff really well, thanks again. says works with oem sensor and or i can buy the sensor and install it as well! hmmm

 

I am sure you are looking at an autometer or like a/f gauge, or a light show as I like to call them. They work 0% of the time, they use narrow band O2 sensors. The TC has wide band O2 sensors stock....

 

DAM that SUCKS, cant return to store, haha have to send to autometer i only got these ones because i figure they read better then cheap ebay ones and they have silver face and orange needle like stock gauge cluster! they look tyte as hell under my cd player in the middle! o well i guess ill be sending it back haha!

so how important is it to have that with FI if im just doing little mods to the SC

 

Here's a link to the 1 of the two large threads I wished would have stayed stickied for more than a week... It talk about a/f gauges for you...
