Hi

I have a 1983 K100.  Just putting the electrics in. I have a Tenet module but the loom is from a K75 I believe. I have got everything matching but just have 2 bits I need help with. I have the original Fuel tank round plug but as the wires are different colours where do I put them? Also the coil wires do not match so how can I get around this? TIA.
