He told me it was a BN2 harness. It is cloth with PVC wires. The pictures I have of most restorations that clearly show the main harness against the firewall are cloth and braid covered wires. I can see the color codes of the braided wires that align with some of the PVC wires of my harness, but I seem to have a few extra wires coming out of the harness where there should not be any. How can I tell the difference between a BN1 and a BN2 main harness that is cloth and PVC. There is also four smaller harnesses of which I am sure one or more will connect to the main harness somewhere. A little bit more to deal with here than my Bugeye that I installed in 2000.Mike MacLean<br clear="none">><br clear="none">><br clear="none">>| | Virus-free. <a href="http://www.avg.com" target="_blank">www.avg.com</a> |</div><br clear="none"><br clear="none">---<br clear="none">This email has been checked for viruses by Avast antivirus software.<br clear="none"><a shape="rect" href="https://www.avast.com/antivirus" target="_blank">https://www.avast.com/antivirus</a><div class="m_6617408040824321430yqt7317314192 m_6617408040824321430yQTDBase" id="m_6617408040824321430yqtfd39485"><br clear="none"></div> </div> </blockquote></div>_______________________________________________<br>
