Too much heat over time will cause the insulation on the wires to dry rot quicker, crack, and possibly short out if the wires come into contact with the head. The early design fits 1994 - 1997 and has. Our test bench consists of a complete engine wiring harness modified with two PCM connectors (one for 1994-1997 PCM's and the other for 1999-2003 units), an IDM connector, 8 injectors and a cam trigger wheel with a CPS mounted to a variable speed motor allows testing up to 6000 RPM.
#7.3 INJECTOR DRIVER MODULE REPAIR KIT DRIVER#
There are two designs of this 7.3 injector wiring harness. Swamp's can now provide complete testing and repair of 7.3L Power Stroke Injector Driver Modules, and testing of PCM's (Powertrain Control Modules). The 7.3 Powerstroke injector wiring harness covers and helps fix what is often a troublesome area. By increasing the voltage on the PC board, this also lowers the current (amps) and lessens heat throughout the under valve cover harnesses to help them last longer. (1994 - early 1997 pictured) This kit contains all the wiring under the valve convers for the glow plugs and injectors. It has been dyno'd on a normally healthy engine to increase by as much as 20hp. This modification increases throttle response by actuating the injectors much quicker, and typically will quiet down injector noise. If you would like to attempt this yourself, here is a nice write-up on "The Diesel Garage" forum This advanced fuel injection system is controlled by the injector drive module (IDM), which works with the vehicle’s on-board computer, and it is responsible for developing the high-voltage signals necessary to actuate the Hydraulic Electronic Unit Injectors (HEUI) utilized by the PowerStroke engine. There are many people who have completed this upgrade themselves with great success, but if you are not comfortable soldering on a pc board, then we suggest not trying this as a replacement IDM is not cheap.
