Wire your stock ECU plug to an aftermarket ECU.

Pick your car and the ECU you're fitting. Pinswap maps every factory pin to the new ECU, checks the wiring and draws the harness. Every pin comes from a manual or a measurement, never a guess.

Covers 10 vehicles and 51 aftermarket ECUs, with 227 harnesses built so far.

Harnesses

Every car against every ECU. A built harness shows its errors and warnings from the wiring checks and its wire count. An empty cell shows the fit check: the ECU's documented specs against what the stock ECU drives. Anything the ECU's documents don't confirm counts as unconfirmed, never as a yes.
