The last item that I installed was an EGT probe attached to a modified Edge Products power module. The power module originally intended to be for 1999 1/2 to 2002 Dodge trucks w/ Cummins ISB engine using a VP 44 pump. This is a very useful module since it has two I/O that can be assigned and several A/D inputs. I kept the EGT probe calibration from the original truck use and modified the module to show digital vacuum. In monitoring the vacuum I can drive conservitively and also see the EGT of gasoline fuel VS CNG. This will help me determine if I have a heat problem when adding too much CNG.

These pictures show the addition of the CNG injector wiring to / from the original gasoline injector wires. The part of the kit that was the most uncertain was where to attach to the OEM injectors. My preference would be to have a "stack" connector where one could detach the stock injector wiring and attach the kit to the injector connector so that the wiring harness didn't have to be cut. I chose the next best thing and attached a Tyco 10 pin weather seal connector in between injector wires from the PCM and the injectors themselves. This way if there is a problem with the Vogas kit or injectors, the harness can be detached and a jumper installed so that the gasoline injectors are wired the same as they came from the factory. Shown in the pictures is the Vogas wire harness detachment and the gasoline injector(s) jumper.

It's alive...Alive!

The installation of the CNG kit on the 1999 Honda Civic was successful. After what seems to have been forever, the kit was finished and tested on September 27, 2008 with the help of Jerad Hanson from whom I purchased the Vogas Propane Kit. We set his Chevy Truck up using the dealer software and the dynamometer at Edge Products. After which Jerad was kind enough to give me some pointers for how the wiring setup should be concerning the MAP and vacuum lines on the Vogas kit. In the ajacent picture, you can see the wiring of the Vogas kit is contained in wire armor. The grey armor houses an extension to the temperature sensor connector which is located on the vaporizor.

Electrical Harness Installation

During the past few days I have been working on installing the waring harness and the Control Module. The harness looks very good and capible of lasting for a long time however none of the wires are terminated (other than the injectors) and none of them are labeled either.

This makes for some challenges as far as identification of wires especially since this is my first installation of a kit like this.

Plumbing the Injectors

After a brief consideration about how best to go about plumbing the injectors, I decided to fasten the manifold to the air filter cover. This provides an easy access to the manifold and tubes and also doesn't hinder access to the air filter. In the case that access to the engine is necessary, there is only one nut / bolt holding the manifold to the air filter cover.
