Question GReddy EGT/Turbo Guage Install Questions

Hey everyone, I finally got my dual instrument cluster pod today and im puttin in my GReddy Electronic guages.

First of all, what is the easiest way to wire electronic guages into your stock harness?

Second, where is the best place to run the wires through the firewall? (EGT sensor and Boost sensor)

Lastly, where is the best place to install my sensors? Ive heard that the third cylinder is the best for the EGT guage, but WHERE exactly is that? Also, for the boost guage, where do i put the t-fitting?

Any feedback would be awesome from you guys that have GReddy guages and please be detailed, im dumb Thanks everyone, i appreciate it.

Oooo! I can answer this considering I just bought 52mm Greddy boost and egt gauges (electronic) and a dual instrument cluster bezel. I don't really understand what you mean by wiring electronic gauges to the stock harness but here is how I wired. I took the red wire and put it in fuse slot 8 I think which is the brake light fuse which should always have power. I grounded the black wire. I put the orange wire in the radio fuse, I forget which fuse slot it was but you can check your owners manual. And I put the white one in the fuse for illumination brightness control. Everything works great that way. Gauges goes all the ways to 760mmHG or whatever when car is off and the backlight goes on when I turn my lights on.

The T-fitting should go right off the stock bypass valve. T it a few inches off that and make sure you have that brass restrictor securely in the T-fitting side that goes to the boost gauge. I mounted the sensor on the empty stud on the battery.

As for the EGT sensor, I think 3rd cylinder is the passanger side one, closest to back of car. So the closest one to passanger seat basically.

Hope I helped.

Thanks for the help
