Every water-cooled Vanagon on the planet will benefit from this wiring harness upgrade kit to replace your old tattered harness and ease your worried mind.

This kit is included in our Alternator Install Master Bundle for those looking for a full alternator upgrade.

Fits: All 1983-91 water-cooled Vanagons (2WD and 4WD). Not for engine conversions.

The Story: The main cable in this harness goes from the starter to the alternator; in addition to being old and often corroded, it is often a bottleneck when it comes to charging your batteries (especially when an auxiliary battery is installed). This new wiring harness upgrades the wimpy stock wire to a beefy six-gauge wire (sealed at the crimp to keep the wire corrosion-free), which will ensure that the alternator is able to efficiently and completely charge your batteries for many years to come.

The other two cables are equally important:
• The blue wire is the alternator field wire. This wire is responsible for turning the BATTERY and OXS lights on the dash off when the engine is running. The proper function of this light is imperative. Not only does it serve to let you know your charging system is working correctly, but it also tells you if your water pump belt has broken (your water pump and alternator are on the same belt). So, if you ever see that light come on, pull over immediately!
• The red wire is the power supply to the fuel injection system. Not much more needs to be said about its importance. The new harness provides a larger gauge cable with new ends for many years of reliable service.

Alternator Wire Upgrade

Had to get a new alternator and this wire upgrade was a great addition in my 1987 Westfalia, it needed new wiring with the alternator and belt. Highly recommended upgrade, very pleased I did this upgrade.

1985 1.9 Fitment

Took me 30 minutes. Most of my time was spent rerouting the wiring harness. This is a cheap way to get the most out of your charging systems. I have no way to verify this but I feel like it did improve the performance of the engine. This is also a great way to upgrade to the higher output alternator, which is what I did.

Easy Upgrade for piece of mind

I think we've all been there where we are working our way through all of our grounds or had ignition issues. I was consuming ignition coils. With this harness, a new GW ignition switch, and a new GW ignition coil, I have not had any further ignition issues. Easy install if you don't mind laying on your back. Would recommend for the piece of mind it adds.

Easy to install, convenient and good quality

I had run my own separate wiring to replace some of the original sub-par wiring that make up this harness to get by while waiting for this part to arrive. I appreciate the high quality of the wiring harness in regards to the insulation and the weather-proofing. I run my Vanagon year round in Alaska and in all weather so this was super important.

Simple enough

I’m not sure how much it helps, but I wanted upgrade while I had the starter out

Original wire harness gone bad

Needed a new alternator and starter, so decided to install this at the same time...super easy to do.

Solid

That, just about sums it up. Solidly built! Solid on performance! Noticed a much stronger charging performance from the alternator on the gauge in the dash. Solid 13.7v. Would recommend this upgrade for any Vanagon.

Good Kit

This is not super easy to install. Just do your research before you think replacing the harness will only take an hour.
