In no particular order below is a list of my favourite motorsport wiring themed Instagram accounts.
Joel from STRD (Speed Theory Racing Development) creates high quality mil-spec looms under his "Race-Spec" brand. Follow his account @racespec, check out his handlay concentric twist photos and several high profile Honda drag car customers.
Ryan and his team at Ry Wire offer a huge range of Honda and Nissan mil-spec wiring looms right off the shelf. Check out the Ry Wire behind the scenes action on Ryan's @ryan_rywire Instagram account. Full disclosure, Ryan from Ry Wire presents our motorsport wiring course.
And of course you can follow me at @senbilcock
