Does anyone here know if the APC kit will work on a 97 model truck. I want to get an Auxillary Powertrain Module to use in the winter time to warm up the truck quicker. I am wondering if it is a plug and play device.

 

Stupid question: What is APC kit?

 

for long idle times you are supposed to have a second pcm to take over, alot of the powerstroke buses have the little black boxes next to the driver with a bunch of buttons and a digital display, same thing

 

Yes, it is basically a manual idle override box. It has a disply that has multi-funtions, but allows you to set your idle where you want it for warming up. When you push the brake pedal it drops it back down to the set idle speed.

 

How about a broom stick handle cut off at a precise length to jamb against the seat. I use my telescoping window scaper.
From the service manual.

Connector is a round 4 wire connector in the center of the intrument panel. Wire colors:
White w/Pink
Black
Pink w/Light Blue
Tan w/ Orange

 

The broomstick handle could very well work!!

 

You could do this and save money.

Ok to start off with you will have to go to Radio Shack or similar store and get some parts.

Single Pole Single Throw Switch. Radio Shack pt# 275-612
5K Linear Taper Potentiometer. Radio Shack pt# 271-1714
Linear PART # for the 2K is Radio Shack pt# 900-8587
2 Single Pole Double Throw Auto Relays Radio Shack pt# 900-2391
2 Wiring Harness Plugs Radio Shack pt# 900-2396
18 Gauge Wire
SOLDER
Wire Ties
Butt Connectors
Soldering Gun
Safety Glasses

STEP 1 Switches

Find a power source that is with the key.
Run a wire from there to one side of the switch.
From the other side of the switch run a wire to the coil terminal of both relays
From the other side coil terminals on the relays run a wire to the parking break switch wire. (There is only one wire on the parking brake.)

STEP 2 Idle Validation Switch (IVS)

As you look at the throttle pedal you will see a switch on the left side with 2 wires going to it. The wires are taped together carefully un-tape them so you can work with the wires. I used a razor knife to cut the tape, but be careful not to cut the wires. (There should be a red/orange with and a brown wire, unless they changed the color code of these wires.)

Cut the red/orange wire leaving plenty on the switch side so that you can splice onto it. The red/orange wire that is going into the wire bundle needs to get hooked to the common side of one of the relays.

The other red/orange (the one attached to the IVS) goes to the NORMALLY CLOSED CONTACT (NC) of the relay. Now take a wire from the NORMALLY OPEN CONTACT (NO) and run it over to the brown wire by the IVS, you will just tap onto this wire so you don’t need to cut it. Just take some of the insulation off and solder it on, then tape her back up.

STEP 3 The other Relay and the Throttle Position Sensor (TPS)

Throttle Position Sensor (TPS) is located on top of the pedal and has 3 wires going to it. Remove the tape to expose the wires. (There should be a brown/white wire and a gray/white wire.)

Cut the brown/white wire, leaving enough to work with by the switch. Hook the end up that goes back into the wire bundle to the common side of the other relay.

Take the side that goes to the switch and hook it to the NORMALLY CLOSED CONTACT (NC) of the relay.

Take a wire from the NORMALLY OPEN CONTACT (NO) of the relay and go to the left terminal on the POT.

Now take a wire from the center terminal of the POT and tap it into the gray/white wire.

Tape up all the bare wires and enjoy

 

Thank You Wreck, I may just give this a shot!

 

what will the high idol RPM be on the mod that wreckit72 posted. i think i would be more interested in the APC kit. i also wanna think you can have high idol on a TW chip.? someone correct me if im wrong. if im not wrong what is the TW RPM?

 

I believe that the TW chip high idle is 1100 RPM's. You can adjust the idle with the potentiometer in the AIC Mod above. Here is a site with pics of the above mod. http://www.northtexaspowerstrokes.com/mods/aic/

 

The APC kit is pretty nice. I want a clean look, easy install. It plugs right in and can be removed without trouble.
