Rywire One-Piece Charge Harness - Honda B/D/F/H/K-Series Swap Harnesses (charge-harness)

Rywire charge-harness is the one-piece starter and alternator power lead set for Rywire Honda engine swap harnesses. Two 8-gauge cables run from the Rywire harness fuse box to the starter and to the alternator, so a K-swap, B-swap or H-swap bay gets clean, correctly sized charging wiring that matches the rest of the tucked harness.

Why This Charge Harness for Your Honda Swap

The Rywire charge-harness supplies the two 8-gauge starter and alternator leads a Rywire Honda engine swap harness needs, cut and routed for your engine family.

• Versus making up your own cables: this Rywire charge harness arrives as two finished 8-gauge leads, fuse box to starter and fuse box to alternator.
• Versus reusing factory charge wiring: this Rywire charge harness matches Rywire tucked and mil-spec routing; it is not designed for factory or other-brand harnesses.
• Battery relocation: with this Rywire starter lead in place, a heavy-gauge cable from battery to starter feeds the fuse box through that lead.

Best for: Rywire D, B, F, H or K-series engine harness installs not running their own alternator power lead.

Frequently Asked Questions

Do I need this with a Rywire engine harness?

If you are not running your own alternator power lead, yes. Rywire offers it as the "One-Piece Charge Harness" add-on on their engine harnesses; this listing is the same harness sold on its own.

I am relocating my battery. How does this work?

With the starter lead to the fuse box in place, run a heavy-gauge cable from the battery positive terminal to the starter and the fuse box is fed 12 V through that lead.

Will it fit a factory Honda harness?

No. Rywire builds it for their own D, B, F, H and K-series engine harnesses only. Email service@tunedbyshawn.com with your engine, chassis and ECU before ordering if you are unsure which configuration you need.

Do I need the Rywire charge harness with my Rywire swap harness?

Yes, unless you run your own alternator power lead. The Rywire charge-harness adds the starter and alternator leads to the Rywire harness fuse box.
