Extra wires on DBW harness I recently bought a DBW harness from another member which is great! I am getting ready to install it and was just going over the wiring diagram. All the wiring diagrams that I can find, show only one loose wire but my harness seems to have three. I checked the locations and colors of all the rest of the right wires and they match up perfectly. I seem to have two extra wires in the B12 and B13 slots of the connector that goes into the computer. Has anyone else run into this? I suppose I could just keep them, but I figured I would check first. Thanks in advance for any help or advice!
This is the wiring diagram I am using: https://documents.holley.com/199r10522.pdf

At first glance a few things come to mind.
- There doesn't seem to be a correlation between the Holly attached doc and the issue.
- How does the DBW relate to the Holly doc?
- What ECM are we talking about?
- Have you started the engine?
- Pics help...

Thanks for your reply.
1. That document shows the connectors for the harness and which wires/pins go to each. It shows that there is nothing listed for B12 & B13.
2. It is the wiring diagram for the DBW harness for the Holley Terminator Max X ecu that I am using. This is the harness that seems to have 2 extra wires.
3. Holley Terminator Max X
4. No. I am still finishing the wiring
5. I will post a pic of the connector with the extra wires shortly

I spoke to the seller and he did not add anything. He took it outbid the box and never touched it. I am thinking it was for a dominator originally. I will Delong the extra wires and I should be good to go. Thanks!
