Wiring Harness Restoration Frequently Asked Questions

 

How does your service work?

You send us your harness or we find a core harness to rebuild. We test and inspect the harness and give you some options. They are “repair”, “restore” and “upgrade”.  You decide which works best for you, we send you an invoice and get started. If you don’t like the options we send the harness back to you, at your cost, or give you an offer to buy it.

 

How much does it cost to rebuild my harness?

Every harness is different. All harnesses will have some oxidation on the connector pins and ends but oxidation will inhibit soldering. So all oxidation must be removed to get a good clean solder, especially if you have a computer controlled vehicle. On average, for a normal under hood harness, the cost runs from $200 to $1000. This is without any upgrades and the price depends on the oxidation level, condition of the plastic connectors, and how large the harness is.

 

How long does it take?

We wish we had room for 500 techs to build harness but we don’t. Due to tech limitations, space limitations and volume we have an average rebuild time of 4 to 6 weeks. It can be less and it can be more. Some harnesses take a long time to get the pins deoxidized. There is no way to know how long it will take until we start cleaning them. Sometimes oxidation comes off easy and sometimes it is stubborn. During the cleaning process the connector pins will become too thin and we will need to replace them with ones from our reclaim stock and that adds to the time. We always say “restoring a harness is more like restoring a painting than rebuilding an alternator”.

 

Is there a refund if I decide I want to cancel the order?

This is custom work, due to the fact that it is difficult to find a buyer for a harness that may fit one specific year vehicle only, we can’t offer cash refunds or credits. However we can take it on consignment and sell it for you.

 

 

Can you build me a new harness?

Yes, but it would be very expensive and the quality would be very low. To build a new one it would require us to buy aftermarket reproduction connectors. That would be expensive but the larger issue is that the quality would be very low due to the low quality of the aftermarket connectors. It is always better to rebuild a harness that build a new one, both quality and price.

 

I am doing an engine swap, can you join the two harnesses together?

Yes and we can make any upgrades, remove unneeded components, modify it in any way you need, and make it look factory.

 

I bought a used harness for my vehicle but it does not fit, can you help?

Wiring harness are not like any other part on a vehicle, it is very common for a harness to be a one year only. This is because the harness is one of the most expensive parts and one place that the manufacture tries to save money. The customer is constantly the research and development department. This is the reason why they only support harness for 7 to 10 years, it would take up a lot of shelf space to support them. Even though a body style, engine, transmission and accessories did not change for, say five years, there may have been 4 different harnesses.

 

Can you find a harness to build for my vehicle?

Usually yes, the problem is this, harness tend to oxidize faster when not in use. When someone needs that one connector they cut it from a harness when they are browsing the wrecking yard. And finally, rodents love to eat the insulation on soy based harness, so your harness is likely to be in better condition than the one we find. There is the problem of finding an exact match, we recommend this, we find a core, build it, and have you send in your harness so we can double check that it is an exact match.

 

My harness is missing insulation or it is brittle and flakes off, why?

Thank the manufacture for that, in the late 80 they went to biodegradable insulation, first round was soy based. Then they learned that rodents love soy, round two. This time they changed the formula and rodents no longer feasted on the insulation, but guess what. Heat makes the second generation of insulation brittle, perfect thing for underwood insulation, where it is very hot. The answer to this is to use industrial grade wires, they are not biodegradable. The fact is this, a harness from the 60s through the early 80, should, in theory, last 100 years, usually not due to other factors. That 20 year or so had the best automotive harness, but fuse technology was lacking.

 

Can you upgrade by older harness to modern fuses?

Yes, we can replace your fuse box with modern fuses and give you onboard relays and flashers.

 

My harness was in a fire, can you rebuild it?

That is a tough one, most likely yes. However the wires next to the ones that burned will have been overheated. That heat will result in higher oxidation levels. The deciding factor is if the connectors are damaged or not. If they are, then it is better to find a core harness to build and use your connectors as needed, if possible.

 

How much will you pay me for my harness?

It all depends on the condition, you will need to send it in so we can test and inspect it, then we can give you a quote.

 

Do you accept payments?

Yes, usually we recommend a half down, but we are flexible. It works like this, you pay the down payment and we start work on it. There are no requirements on additional payment amounts or frequency. When we have worked through the payment that you have “banked” we put the work on hold until you make an additional payment. We don’t want to have harnessless abandoned so we ask that you send us an email at least once a month regarding the payment, just let us know if you are paying that month or not. Of course we can’t ship until the payment is paid in full. We charge 4% on every payment after the first one, it covers the additional credit card charges. You can avoid that by sending in cashier’s checks.

 

Can you test my computer, sensors, and switches?

Yes, we are happy to so, there is no charge for computer testing, but there are charges for some sensors and switches.
