So Ive seen a few posts with people asking how to set up DBW on the haltech. I recently got mine set up and operating perfectly. Im just posting my pinout for others to use/see. Im also using the FD rywire harness for the haltech. So I hope this helps someone at some point!

Had a local shop make a custom wire harness to connect everything. It was easiest and cleaner not to use the IAC or TPS wires and just pin into the ECU plugs separately. However I did use the +5v off of the TPS.
