VW ABA Swap Wiring Harness
Brand new. No core required. Ready to install.
We are now stocking brand-new VW ABA swap harnesses, eliminating the need for core returns or downtime. Simply place your order and receive a freshly built harness, ready to install out of the box.
If this makes your life easier—good. That’s exactly what it’s designed to do.
Built for Maximum Swap Flexibility
With fuses and relays integrated directly into the harness, no external fuse box is required. This allows you to run a VW ABA engine in virtually any chassis—Honda, Toyota, Rabbit, Scirocco, off-road builds, track cars, and more.
Fabrication is still required for engine mounts, as with any swap, but we’ve made the wiring as simple and clean as possible.
⚠️ This harness is designed to work with your factory VW ECU.
It is not a standalone ECU wiring harness.
