EMPI Complete Wiring Harness | VW Beetle Sedan & Convertible 1966 | German-Style Reproduction, LHD (98-9485-0)

EMPI Complete Wiring Harness — VW Beetle Sedan & Convertible 1966 (98-9485-0)

If your 1966 Beetle has a headlight that dims when you hit the brakes, a horn that works only when it feels like it, or a dash you have already been inside of three times this year, the problem is almost certainly not the switch you keep replacing. It is sixty years of oxidized copper, brittle insulation and other people's repairs stacked on top of each other. This is EMPI's complete reproduction wiring harness for the 1966 Beetle sedan and convertible — a brand-new loom built to the factory German pattern, with correct wire gauges, correct colors and factory-style terminals, so you can throw the old one away instead of chasing it. EMPI part #98-9485-0.

What Makes a Reproduction Harness Worth It

You can rewire a Beetle with a generic kit, and plenty of people have. What you end up with is a car that exactly one person on earth understands. A year-correct harness solves a different problem: every branch arrives already cut to length, already routed the way the factory routed it, and already colored to match the 1966 wiring diagram printed in your Bentley or Haynes manual. Nothing needs inventing. Every connection you make is a push-on terminal at the component it belongs to, not a crimp splice buried behind a kick panel. Ten years from now, when something does act up, the diagram in the book will still describe the car sitting in your garage. That is worth more than the price difference.

What's Included

• Complete loom — main harness, front section and dash wiring
• Individually packaged, numbered branch wires so every leg is identified before you pull anything apart
• Factory-style connectors, terminal ends and grommets
• Correct wire gauge with German-spec color coding and tracer stripes
• Printed installation instructions

Not included: fuse box, ignition and light switches, bulb holders and battery cables are all separate parts. On a car getting a full rewire, plan on a new fuse box and a fresh battery ground strap in the same session — corroded fuse clips and a tired ground strap will make a brand-new harness look defective.

Vehicle Fitment

• VW Beetle sedan and convertible — 1966 (sedan, sunroof sedan and cabriolet)
• Left-hand drive only. RHD cars route the dash section differently and need their own loom.
• Works on the car's original 6-volt system, and equally well after a 12-volt conversion — voltage does not change the routing

1966 was the last model year US Beetles left the factory with a 6-volt system; 12 volts arrived for 1967. If your car is a 1967, this is not the harness — see 98-9486-0. And unlike the earlier sedan-only looms, EMPI lists this one for both body styles, so convertible owners are covered by this same part number.

Technical Specifications

Before You Start

• Disconnect the battery ground first, and leave it off until the very last connection is made
• Photograph everything before you cut anything — behind the dash, at the light housings, and where the loom passes through the tunnel and body grommets
• Pull the old harness out in one piece if you can, and lay it beside the new one to confirm branch routing before you start installing
• Clean every ground point back to bright metal. A new harness will not fix a rusty ground bracket, and most "bad wiring" complaints on a freshly rewired car turn out to be grounds
• Set aside a weekend. The work is not hard, but it is slow and fiddly with the seats and dash trim out, and rushing it is how mistakes get buried

Frequently Asked Questions

Does this fit a 1967 Beetle?
No. VW changed the harness for 1967, and the 1967 loom is a one-year-only part. Use EMPI 98-9486-0 for a 1967 car.

Will it fit my 1966 convertible?
Yes. EMPI lists 98-9485-0 for the 1966 sedan and convertible together, so cabriolet bodies are covered by this part number.

My 1966 has been converted to 12 volts. Can I still use it?
Yes. US 1966 Beetles were 6-volt from the factory, but the routing and branch layout are identical either way, and the wire gauges were sized for the higher current a 6-volt system draws — so they are more than adequate at 12 volts.

Does it come with a fuse box?
No. The fuse box, switches, bulb holders and battery cables are sold separately.

Are the wires marked so I know where each one goes?
Yes. The branch wires are individually packaged and numbered, and the colors and tracer stripes follow the factory German scheme, so they line up with a period 1966 wiring diagram.

Can I use this on a right-hand-drive car?
No. This is a left-hand-drive harness only.

Can I install part of it now and finish later?
You can, but it is harder. The harness is one assembly, so a partial install means running the new loom alongside the old one and living with both — most people find doing the whole car in one go is actually the faster route.
