Vehicle electrical & technical services
From everyday electronics upgrades to complete custom wiring and leisure electrical systems, JRGM Technical Services LLP carries out specialist workshop-based work in Tillicoultry.
What we do
One workshop, several specialist disciplines.
JRGMTS covers modern vehicle electronics upgrades, electrical diagnostics for older, classic and custom vehicles, classic and hot rod wiring, custom looms, and campervan / motorhome / caravan electrical systems. Most work is carried out at our Tillicoultry workshop so it can be tested and integrated properly before handover.
