Hello all!

I'm looking toward hooking up a few gauges on my truck. I just wanted to know what yall's opinion was on how I should go about doing this. I was told that I would have to do all this drilling and tapping and that just doesn't seem practical to me! I popped the hood today and sat back and looked at her and came to the conclusion that wouldn't it just be easier to hook into where the rubber line leads to the map sensor? Meaning, its right off the intake plentum, and its basically going to be the easiest and probably the most accurate reading, and no headaches!


Would that be the way to go?



Second question:

If that is the way to go, what size "Y" or "T" fitting should I use to hook up to the rubber line that runs to the map sensor. I'd cut it and then see what size it is then go get the fitting however its my only vehicle to drive. Hopefully someone knows the exact size of the rubber line LOL!

Thanks!!

Alot of people use to do that just put a T in the map line but now its just alot easier to just get the riffraff AIH Delete plug with boost fitting .

Riffraff Diesel: RDP AIH Tapped Fitting

 

I would get the IAH delete plug from Clay...

but if not, a 1/4" tee with two barbed fittings, and one 1/8" compression fitting is what you need

 

Thanks! I'll order the AIH Delete Plug tomorrow. That seems alot easier.....and more sensible. Thanks!

i DID AWAY WITH MY WASTEGATE AND USED THAT LINE FOR BOOST PSI.

 

GREAT! THAT SOUNDS VERY NICE...

Your yelling FYI...

 

Isnt the AIH usefull to us in cold weather areas? is there another location we can put a boost gauge in?

 

No, it actually rarely even comes on. You have to have the following things fulfilled for it to activate.

- Parking brake on
- Trans in Neutral or Park
- Glow plugs off - That can take up to 120 seconds in cold weather
- Ambient Air Temp below a certain point, IIRC 32*
- Battery voltage <12v

It was put in for emissions, and doesn't help a cold start situation. The AIH only came on the Late 99-03 trucks, the Early 99 never had it.

 

so when you take it out you unplug it and thro it in your toolbox? does it set off any codes in the computer with it gone?

 

Just follow the wires to where they terminate and unbolt them. You will get a soft code, but you will only see it when you check, it won't set the SES. You can cure that with a simple inline resistor if you want.

 

so the soft code doesnt cause limp mode or anything? sounds good.. i need to hook up my autometere boost gauge, i first need to figure if i want it in a pod or what though..

 

No limp mode... Just a soft code...0541 IIRC...
