New Headlight Relay Kit available from Pelican

[JWest]

Following our highly successful line of electrical products for the 914, JWest Engineering has introduced the Headlight Relay Kit for the 1974 to 1989 911.

With the relay kit, the electrical current travels straight from the battery to the headlight circuit at the fuse box, greatly reducing the load on the headlight switch and the failure prone column switch.

In addition, more power is supplied to the headlights for maximum light output.

Our easy-to-install kit uses factory connections and mounting points. High quality screw-together terminals join the new and old wiring together. No crimping or drilling required to install.

Due to the size of the factory wiring from the fuse panel to the headlights, the bulbs should be limited to a maximum of 100 watts.





You can order through Pelican:

What about pre-1974?

The wire lengths and terminals in this kit were made to fit perfectly into a '74 to '89 911. The early cars had a different fuse box location that changed in size over the years.

If there is enough interest I may create a long-hood version in the future, but for now the current version could be adapted. This would require finding an appropiate mounting position and possibly changing the power and ground wire lengths.

If it simply a matter of increasing the wire length to accommodate all model years you may consider it as your available market will expand for not a lot of additional cost. Though, perhaps it is not so simple.

Best regards,

So I've heard of relay kits for the purpose of accomodating higher wattage bulbs...

Do I understand correctly that this kit will improve the light output of any setup, such as my existing H4? If so, for a great product.

...with spiritual consolation to flat6turbo I should imagine....
Hey! I recently got my Pelican sticker!

Thanks. It actually would make a messy install for one of the applications, and I don't want to compromise the quality of the product to accomodate more years. One product at a time...

The 911 has a less robust design than most cars - not only running the circuit through a conventional headlight switch but also using very small contacts in the column switch to carry the headlight current. Saving this switch from imminent failure (even with stock bulb wattage) is the primary concern.

Because the relays cut out a portion of the circuit path that travels back to the dash, through multiple contacts, and back up to the fuse box, the voltage drop is less and the existing bulbs will likely produce more light output.

The current for higher wattage bulbs are easily carried by the new relays, but the headlight wires further downstream are smaller than 14 AWG. This limits how much load should be placed on the circuit. The factory connectors on the back of the headlight can also melt if exposed to too much heat from powerful bulbs. So the kit is limited to 100 watt bulbs due to the overall system design.

So is the stock wiring adequate for 100W bulbs + relay?

thanks

Yes, the stock wiring is fine for up to 100W bulbs once the relay kit has been added.

Sub'd. My next upgrade, I think.
I hate to display my ignorance, but will the dash lights be brighter?

Does this kit offer any advantage over the Sucro relay kit or is this just another option to consider?

High quality screw-together terminals join the new and old wiring together. No crimping or drilling required to install.

I'm curious about this bit. The factory power cables run from the switch to the fusebox for distribution. When you install these relays, you need to take that existing cabling and use it to energize the relays when powering the beams. If you don't crimp or solder, how do you tie those existing cables into your kit's integrated wiring?

No effect on dash lights.

I'm not too familiar with the Sucro (never had one in my hand), but as far as I know they accomplish the same task. I don't know how that kit is terminated or mounted to compare.

The JWest kit is available for immediate ordering from Pelican.

Good question - I'll explain a bit further. On the connections to the factory feed wires we have a special butt connector (posi-lock) that uses a compression fitting on the end of the wire.

I was going to install the JWest 911 Headlight Relay Kit that I picked up from Pelican, but as you can see in the picture there are two differences between my vehicle and the instructions that came with the kit:

1. my wires on terminals 6 and 7 are olive and gray, not yellow and white - would it be safe to assume that these are the correct two and proceed based on their location rather than on their colors?

2. hanging off the forward lower end (right side in photo) of the fuse block, using the screw that is to be used to hang the relay kit is a relay or terminal block of some sort that is occupying the space intended for the relay kit. It has the number 944.612.551.00 on it - I think it's an OEM part, but can't say for sure since I was not original owner. This is a 1988 911 Coupe with a sunroof - it has no rear wiper and no headlight washers - these are some of the items that pop up when I search on this part number. Anyone have any thoughts? Main concern here is best way to mount the relay kit (in addition to addressing the wire issue above - don't want to start cutting terminals off the wires and find out I cut the wrong ones).

Thanks for any help.

I bought the relay set when i was out in Ventura from the booth. Installation was pretty easy. My fuse panel had the headlight fuse numbers different than the instruction sheet noted, but not a problem. I recommend a 12volt testing light to help identify the correct wires for low and high beams. Very nice setup. I think it took me about 30 minutes.
