Electrical systems design for specialist vehicles and low volume automotive prototypes

HCI can offer a full design service and can build to print. We can assist in design checking and complete pre-production feasibility studies, prototypes and lab car builds. We build our automotive harnesses on 1:1 scale formboards which are usually created using Zuken E3. This guarantees repeatability, ensuring the first prototype harness is the same as the 1000th.


We create Standard Operating Procedures for each wiring harness in build to ensure continuity of information between harness build technicians. All tooling is logged, calibrated and checked using our crimp pull tester and all completed harnesses are 100% checked on our Cirris CH2 automated test equipment for electrical continuity and insulation resistance.
