DISCLAIMER : I am not responsible for the modifications you make to your vehicle.

So I have seen alot of people trying to install the comp. package Boost gauge and ladder tach, This is how I have installed 2 of them WITHOUT the amishland harness.

Remove the upper trim cover above the Steering column. Just pull up, it will come loose.


After that removed the Radio bezel. Grab both a/c vents and pull really hard.



Unplug the Hazard switch so you can take off the bezel


Next take of the 2 pockets on the left side for later and the door sill. They all just pull off.



Now remove the lower trim panel for the steering column 7MM bolts 2 of them


Just take off the left section


Under the dash board by the hood release lever pull the carpet back and follow the big bundle of wires to the rubber insulator you need to run the wires through.


The screw driver is pointing towards the insulator


CAREFULLY poke a hole on the surrounding rubber, I used a flat head screwdriver. Then pull the wires through


Both White and Black wires are through.


Now slide the lever over and unplug the PCM Connector 1


Carefully pop the black cover off and expose the wires


Now find the Pin Lock tab and slide it out


Now find pin number 31, they are numbered .


Here I will make it easy for you, Its the blue plug 1/2 way out :)
Yes it just pulls out.

Now you need 2 of these from saturn 22692904


Now push it into hole 31 until it clicks


Re-secure the harness with a zip tie


Now the bottom PCM connector number 3 only has one blue plug in number 10 slot thats your next pin (same things as the top connector, make sure to remove the pin lock slider out of the side)


Now install the black covers


Now connect your black wire from the firewall to the BOTTOM Pcm connector wire. Then connect the TOP Pcm wire to the white wire from the firewall. Apply loom as needed and run wires to make it look nice and clean. (you see the new wires? look closely at the bottom of the connectors.


Now for the Gauge.
Cut Off BOTH connectors then wire the 2 pink wires together and the two grey wires together


Now wire the solid black wire and the Black wire with a white strip together (they are grounds) Then put a connector on the brown wire and the white wire.


Now run a ground wire to the bolt next to the radio, and then run a wire and tap into the WHITE wire on the hazard switch like so


Now use a "add a" fuse to the 12v fuse on the fuse panel. I didnt have one :( Then run that new wire up to the steering column with the other power and ground wires from the radio hazard switch area.


see the new wires dangling in the left of the picture


Now take the power wire from the hazard switch and connect it with the 2 grey wires from the gauge. Then Take the power wire from the fuse panel and connect it with the 2 Pink wires at the gauge and Now take the black wire from the radio area and connect it with the two black wires at the gauge.



Now the Top PCM wire which should be white goes to the WHITE wire on the gauge assembly. Then the black wire from the bottom PCM connector goes to the BROWN wire on the gauge assembly.


Now pop the gauge in place and re-install all panels. Turn the key to the run position don't start the car, and hold the center button on the back of the gauge assembly till the lights flash. Now cut the ign. off and then start the car. The lights should do a light check sequence and the gauge should spring to life.


I really hope this helps. Check with your local tunner and see if unplugging the PCM will require you to re-tune. I dont think it will but beter safe then sorry. I am on a GM stage 2 tune and had no problems.

Nice work guys!!! Should be a How-To!

And disconnecting the PCM connectors does not affect your tune...At least not mine.

No problem guys. It did take me about an hour to get it all together for the write up, and get it posted. NCStateRedline really wanted to have some one post the info. Seemed like a good idea :). Anyone else think this is sticky material? :bananahum

Stickify this. Seems pretty easy. If anyone has run a wideband, this is just as simple if not more simple than that.

No problem man. I dont mind helpin out.

Yea its not that hard at all as long as you have those two wires from saturn, with the PCM connectors on them. Then its a walk in the park.

Great write up, and good pics are priceless for an install like this. The Comp Pack boost and ladder tach is the way to go. Keeps the OEM look, the shift lights are a huge plus. I used the Amishland harness way back when, and can't imagine the car without the gauge there. Hopefully this will help some of the people here that have wanted one for a while.

Hey, when you say the white wire from the hazard switch, all that i see on mine is a gray, white and black, and a blue one. I'm assuming you meant the white and black... Just making sure

Its been a little while since the install but it should be the grey wire, if i remember correctly. Just double check with a multimeter just to be sure. ( I want to say NCStateRedline and my car the grey wire looked white in person. Grey in a picture)

So the wire i'm supposed to tap into on the hazard switch is the gray wire? You should change that on the first page because i already did it tapping into the white/black one. :bangin:

When i had the wire in my hand during install it was white i promise, lol. The pic looks grey and the wire to look for is the SOLID, LIGHT color wire should be the one you are looking for :) Given year models may make a difference in wire color, haven't checked into that possibility.

why are you tapping into the baro signal, the first blue connector for the pcm?
