Installing the Isspro Turbo Temp Monitor R4130

*Special Information for the Dodge 24 Valve and Ford Excursion included below*

These instructions are to simplify the procedure and are NOT intended nor should they be used to replace the Isspro instructions provided with the Turbo Temp Monitor.

The Monitor requires the use of a thermocouple installed in the exhaust system. This thermocouple can be used in conjunction with a pyrometer. It also requires a lead wire to be connected from the thermocouple to the pyrometer or directly to the thermocouple. When using the monitor with a pyrometer the wires connecting the pyrometer to the monitor must be 22 AWG or larger. Remember when wiring the lead wire to the monitor the yellow wire is positive (+) and the red wire is negative (-).

The monitor is also wired to the positive (+) side of the battery using a #16 AWG wire or larger.

The monitor is then wired into the ignition system of the vehicle. The easiest way is done by finding the ignition wire and using a scotch-lock connector to connect the wire from the monitor to the ignition wire. Finding the proper ignition wire may require locating a wiring diagram for the specific vehicle. If such a wiring diagram is not available you may need to use a meter and check the various wires coming from the steering column. Be careful not to damage any of the wires in order to prevent a short in the future. We will provide a list of vehicles and wire colors that we receive as we are informed by customers or have found ourselves. The list as it currently stands is as follows:

1999-2001 Ford Pickup Red wire with dark stripes
2002 Ford Pickup Red wire with a green stripe
2000 Dodge Pickup Light blue

I just finished installing an ISSPRO turbo temp monitor on my '98.5 24v. This is a really neat product - it monitors a post-turbo thermocouple (it can daisy chain off of an existing one if you mounted your's post-turbo) and doesn't let the engine shut down until the EGT is below a set temp (comes preset at 300 degrees and you can adjust it from there). It was a little tricky getting it hooked up as Isspro doesn't have vehicle specific instructions. At first I had it wired into only one of the ignition wires and when I turned off the truck ABS and Air bag alarms went off (they are fed off of a different bus). So I had to design a circuit with a relay and a diode to power up the second bus. It now works GREAT!! An added benefit is that I put an exhaust brake on last weekend and now I can start the truck, turn on the exhaust brake, wait about 15 seconds for the post-turbo EGT to get over 300 degrees and then turn off the ignition and pull the key, lock the doors and walk away for it to warm up at idle (takes about 4 minutes to come up to full operating temp in 30 degree weather!) (Don't forget to leave the truck in neutral) When I want to shut down I just turn off my exhaust brake, set the parking brake, turn the truck off and walk away. She turns herself off when she's cool!! I also installed a disable switch on the right side of the steering column right behind the ignition switch for an emergency shut down - turn off the ignition then hit the switch. I'm attaching pictures of the install plus the schematic that I drew. This schematic is out of the factory service manual on page 8W-12-6 (in the 98 manual) - it's the very first schematic in the 8W-12 junction block so you can compare to the schematic and wiring colors in your truck. This setup is much better than the diesel life saver through genos (it's just a timer) and it's cheaper too!

There has been cases on the Excursion when the Turbo Temp Monitor is installed and activated for 15 minutes or more the remote control key fob will not lock or unlock the doors for around an hour after the vehicle shuts off. It has been determined that the security system on the Excursion has an indicator that tells it when electricity is being used and not being replaced. In order to conserve as much electricity as possible the system renders the remote inoperable.

We have a report back from a customer that he installed a jumper wire from the same ignition wire tied to the TTM and ran it to the windshield wiper circuit. The wire is black with a light green stripe (#297 on the schematics). It is also recommended to use a 30 amp inline fuse in this jumper wire and also make sure the wipers are off anytime the vehicle is shut down so that is does not create problems with the TTM. Evidently this prevents the GEM (General Electronics Module) from deactivating the remote key fob.
