I got a good start on getting the Holley wired up. First order of business was getting the crank trigger installed. Look at that beautiful custom pulley! Then I made up a shielded harness for the crank and cam sensors. The harness is made up of a ground, power, and two signal wires along with a bare drain wire. Those were all twisted together and then I wrapped copper shielding tap around all the wires. The copper tape has a conductive adhesive so it bonds to the drain wire. That drain wire gets connected at the ECU end only. Here's the ECU mounted on a piece of painted sheet metal. Now I have a ton of extra space where all the other electronics used to be. I guess I have a place to store chairs for car shows now! I got the majority of the wiring done minus the injectors, IAT, and ECT sensor. I stripped all the loom off the original harness and started to figure out the best way to route everything. I didn't have to tear the harness apart at all. I do need to extend the injector harness though. Holley made that way short compared to the other parts of the harness. The IAT and ECT will also get extened and spliced into the GM connectors. I made up the end for the ignition harness and pluged that in. I routed the wideband through the hole in the transmission tunnel. You can see where the connectors will meet each other right in front of the shifter. I was glad I didn't have to extend that wiring at all. The roll of wires in the passenger footwell area is for the extra inputs and outputs. I will probably leave those there. It's an easy spot to get to without having to rip the carpet out of the car. You can also see the vacuum line for the MAP sensor. I'm just going to cut a hole in the carpet under the passenger seat and leave the sensor there. The TPS needed a new connector, so I decided to cut the stock plug off and put a weatherpack connector on the end. For the IAC solenoid on the throttle body, I had to wire that into an output for the ECU, despite the harness already having it's own IAC plug. That wiring was designed for a GM stepper motor IAC. The Ford IAC is known to be better, so I preferred to keep it. I just won't use the plug in the original harness. I also ran 2 wires from the stock VSS back to the ECU along with a set of wires from the ECU to the dash. The Holley has the ability to interface with an external traction control unit, so I may take advantage of that down the road. I figured it would be a good idea to pre-wire for it now. I also wired in the datalogging outputs from my PLX oil pressure gauge and Fuelab electronic regulator. I will just need to set them up as cusom sensors in the software, but it will be nice to be able to log that information. I'm just waiting on some 18ga wiring to show up so I can extend the injector harness. Once that is done, I should be ready to power up the unit and start checking things.
