Headlight Upgrade Harness's For Sale (again!)


Recommended Posts

After much deliberation and pleading from members who either want more or never had a chance the last time, I am making the popular "Headlight Relay Upgrade Harness's again.

There is only one catch. It's not as cheap as it used to be. Due to suppliers costs, fuel prices, my wifes sanity, and the fact that I no longer wish to work for my current employer (long story), the new price for the headlight harness is $125.00 inside the U.S. Outside the U.S. needs to contact me first be fore making a payment

I appologize for those of you who think that this is too much but I'm sure that if you ask any one who bought one before, They'll tell you that this is a more than fair price for the work that I put into these. It in no way harms the 240Z and as a matter of fact,

1) It stops the fuses from overheating

2) Increases the voltage to the headlight to almost full battery voltage.

3) Saves your headlight and turnsignal switch from future damage due to over heating.

4) completely integrates into your 240Z without any cutting or drilling of any kind.

5) Your headlights will be brighter and allow you to upgrade to H4 headlights.

I only take money orders for the $125.00 and they can be sent to me at ....

I apologize for those of you who think that this is too much...


Well I for one don't think your new price is too much. Let me be the first to say that my payment is on it's way to you. I was disappointed when you said you would no longer make this harness. I commend you for providing detailed plans for all to see as your gift to the Z community. Even with the plans, however, I found that locating and paying for the parts was much more than I had anticipated.

The parts alone, if you only want to make one or two harnesses runs you $40 or more. That is not even including tax and shipping. The copper in the wires is heavy, and shipping adds up quickly. If you buy small quantities of wire locally, the price per foot is much more than Dave can buy in quantity. I spent countless hours trying to find the 3-prong sockets you need to make this harness plug and play, and to avoid cutting into the stock harness. I even spent over $20 with autosparks in the UK for some sockets that looked like they would work but it turned out that the pins and plugs inside the sockets did not match up to the OEM wiring harness. This was an expensive mistake on my part. You can avoid all of my sorrows by just buying Dave's harness already assembled.

So the $125 is more than what Dave offered this harness for in the past. But get real people. When you take into consideration his cost of materials, and the cost to ship the harness to your door, he was essentially doing the assembly work for free. While that was very generous of him, he now wants a fair price for his design, testing and assembly of this harness. So why not help out a fellow Z enthusiast and send your money in today. You will thank yourself when you can see so much better driving your Z home on that dark and stormy night.

WOW! that was impressive. Thank you for that and i'd have to say that you hit it right on the button when you spoke of suppliers, shipping, research, design, manufacturing and everything else.

They are hard to make (3 hours) and it took me two weeks of searching to find all the right parts, suppliers and shipping methods. But thats where I figured that If I wanted one so bad, then everyone else must need the same thing, being as how most of us here have a 240Z or something similar.

I really wish I could fing the black 260Z plugs and the white 280Z plugs. Those are my "needles in a haystack" I can't stand the thought of butchering some ones harness or even an OEM harness out of a wrecked Z. I'd prefer new for a new product. It's like putting Pinto Wheels on your brand new Mustang. it's just ugly.

Since I am the owner of a 280z and would like to be able to run the bright new headlights I just bought when I put everything back together, would you recommend using old OEM wiring from another 280Z to put a headlight harness toghether or to use a pre-fabed kit like the one from VB.


It's sorta plug and play, but not quite like yours from what I can tell.

I have an extra complete engine wiring harness I could take the plugs for the headlights off of to use, but it's in nice shape and I kinda want to keep it incase I run into problems later ...

I'm way to busy to help locate the wire plugs for the 260 or 280z cars at the moment (closing on a house, moving and planning wedding stuff all this month :stupid: :tapemouth :stupid: )

From what I've read on this board about the VB harness, is that it is not plug and play. The wires are too short, you have to cut it to get the connectors inside the headlight bucket, and the wire is so thin the thing heats up once you finally get it in. That is why there is so much interest in Dave's harness.
