TT Conversion Question

[ilian51378]

I have almost finished my TT conversion, but there are some things I need help with.

Okay, I installed almost everything back in the engine bay, but I can't figure out some things.

1.) What do I plug into the big opening on the side of the Y pipe and

2.) What plugs into the nipple that comes out of the pipe that attaches to the air filter

Could anyone help? Thanks!

Also, my gauges seem to act weird. I am using the stock wiring harness for them and they do power on, but this is what happens:

1.) The oil pressure gauge shows all the way up just by turning the lights on and stays that way when I turn the engine on.

2.) The water temperature gauge is affected by the stock dimming knob as the temperature goes up as I dim the lights and then drops when I turn the light all the way up again. It also stays at about 140 F just by turning the lights on. It goes further up when I start the engine.

Another thing is that the oil light on the dash is on and the check engine light is on as well. I am assuming that the check engine light is on, because I haven't hooked up the oxygen sensor and the down pipe yet, but I may be mistaken.

The car idles right on the money and the boost gauge seems to work right. It stays at 2psi at idle and it goes up as I press the gas pedal. That is the number 2 on the gauge below the zero, where the gauge needle stays when it is off. I am not sure what the readings above the zero are for, but the needle goes in that area when I hit the gas, so I am assuming that below the zero is for idle. Again, I could very well be wrong on that too. That is why I need help! Anyone?

Y-pipe opening = BOV connection. T-pipe nipple = BOV as well. The gauges sounds like connectors in the wrong place to be honest. Something isn't plugged in right.

I got the gauges fixed. What happened was that somehow the wires got pinched when we were installing the rear turbo and that caused the oil pressure gauge to act weird and the oil light to be on. The interesing thing is that since I connected the gauges through the reostat, now when I dim them, it affects the reading of the needles on the water temperature and the oil pressure... I guess, I will not use the dimming function.

I also have to install the Derale fan controllers (one for each fan) since the 93 tt ecu does not controll them. However, yesterday I noticed that the A/C fan was on, but that was probably due to the fact that the A/C was on. Does anyone know how to install those?
