The wiring in general on the SP1 is shite, a complete after thought, an appalling harness bound together with insulation tape
WTF when the plumbing is so brilliant!. Mine is currently stripped down and been restored to original spec. Do not think i will be buying another harness, one shitty one is enough. Soldering iron, solder, cable and heat shrink sheathing, all available off the shelf at halfords. The alarm is coming off too. More bollox.
