Are you soldering your connections Terry? There are 2 schools of thought with regard to this. My mate makes race car loomes and does a lot of rally cars. He helped me do mine and supplied all the stuff. I mentioned to him about soldering the ends and he said it was not good practice and he had never built a loom with soldered ends. His reasoning behind this was as follows: When you heat the wire it will change its properties and at the point where the solder ends you will have a weak point in the copper wire that will break if subject to movement. He assured me that as long as the connector is made off properly there is no need for solder.
