Background - VQ35DE installed in a Datsun 280z running a Haltech platinum pro harness. I have used a stock engine harness and connector/pin set to make a custom engine harness. I am bench testing and my laptop will nor connect to the ECU. I have checked my positive and negative leads, usb/ecu cord is new from Haltech, ECU manager is new and reinstalled, I also downloaded the 350z ECU manager...... Still will not connect. For bench testing I am using a 40w 120vac to 12vdc converter. For wiring I used the stock Nissan FSM wiring guide. Please help, this has been a five year road of just craziness and disappointment, I just want to hear it start. :(

I find it hard to believe after buying a 2000$ system that i can not get support, even if I am willing to pay for the information/support.

It is difficult to help you with a product discontinued something like 5 or 6 years ago and you have made a custom loom. Pretty much if the ECU has power and ground it will allow you to go online. You do still have the OEM ECU connected?
