Crimp the appropriate new terminals onto the freshly cut wire ends. Insert the terminals firmly back into the ECU plug housing until you hear a distinct click. Tug gently on each wire to verify it is locked in place.
When you repack an ECU (moving its brain into a different housing or adapting a generic board to a specific car), you alter the thermal and electrical environment. A design that works perfectly on a bench will fail inside a 100°C engine bay with vibration. Your design phase must account for: ecu design pinout repack
The hardest part of a repack is connecting the new PCB’s pads to the old case’s connector pins. You have two options: Crimp the appropriate new terminals onto the freshly

When mapping your pinout for a repack, categorize every wire into these five buckets:
Always verify the pinout with a multimeter and a known ground. Never trust a forum photo. Automotive manufacturers changed pin functions mid-generation without updating connector faces.
