Default Fed the engine harness.....

.....through the hole in the firewall today. I carefully deburred and sanded the inside of the hole smooth with 180 grit paper and touched it up with some black paint to keep the edges from rusting beforehand.

Here you can see where the main harness branches off into several smaller ones, that part of the harness will reside just behind the passenger side cylinder head.



I cut the hole in the grommet to 3/4" using a piece of 3/4" I.D. tubing with the end sharpened, the main harness is about 15/16" in diameter. Using a fresh new razor blade I made a cut in the grommet.



The engine harness fits pretty nicely, there is enough room for it to tuck against the firewall away from the back of the engine. The grommet went in easily and will need some sealer around the harness later when I'm through messing with it, if I don't like the way it's working out I can buy an aftermarket split grommet later on.

The wiring provided (blue, green & pink) for control of the fan relays can be seen at the very bottom of the pic. I have two Bosch 30 amp relays here (0 332 019 150) that perhaps I can use for the fans, I'm not sure if they're the correct ones to use.



I need to come up with a bracket or plate to mount the ECM (Engine Control Module) in this spot just to the left of the passenger side kick panel. I can't get it mounted up any higher as it will interfere with the A/C unit. It will be up high enough to be out of the way of my passenger's feet, but still easily accessible.



I can mount this TCM (Transmission Control Module) unit over the top of the ECM, leaving about an inch of air space between them for cooling airflow.



With the engine side of the harness out of the way it doesn't look too bad in here. On the driver's side you can see the 4 fuses (#1- Battery, #2- Injection & Ignition, #3- O2 heaters, #4- Fuel pump) which can be mounted right next to the original fuse panel.

On the trans hump is the diagnostic port/check engine light unit. Closer to the firewall on the hump is the wiring rolled up for the cruise control, brake switch (for cruise control disengagement, needs to be a 4 terminal type of brake switch), tach, electric speedo (which I won't be using) and A/C compressor.

On the passenger side is the ECM unit and fuel pump relay. The ETC (electronic throttle control) pedal harness has a little extra length that will need to be looped and tied up. All in all it should be a pretty simple and neat installation when it's done, of course figuring a few things out along the way will be more than just a little challenging.



Tomorow I'll try to fab up the mounting brackets I need for the ECM and find a home for the fuses, fuel pump relay and diagnostic port/check engine light unit.
