JB4 Custom Fuel Wire Harness

This plug and play quick install adapter allows you to install a posi-tap for fuel control tuning without piercing the factory O2 sensor wiring providing a completely reversible connection.
Update

Some good news and some bad news.

Good news: I wrapped up the creation and testing of all the harnesses this morning.

Bad news: The priority mail padded envelopes, which are not carried locally, that I ordered on 9/5 just shipped on Thursday. Therefore there will be a delay in shipping until shipping materials arrive.

Thanks for the update!

Hopefully, neither snow nor rain nor heat nor gloom of night stays these couriers from swiftly delivering the needed packing supplies.
 
Thanks Ecko. Any chance you found a single harness laying around somewhere?
No worries if not, but just checking. Thanks!

Yes, I have your single harness. I need to shorten it a bit.

Sweet, I should have it in time to install it for a week or two, then probably disconnect the whole JB4 because snow will be flying.

This is what happens when you procrastinate, lol.
 

No. I only have mine here and on N54Tech. There are some technical missteps with the ones on eBay even though they should work assuming the butt connectors hold. They have taken their longer 12” extensions, cut them in half and use butt connectors to reconnect the wires to give the appearance of a shorter harness. They then tap wire 1, give you a spade connector? Do you they include the other end of the receptacle to crimp onto the JB4 wire? There ends up being 6 potential points of failure, not counting the connectors, in each harness. I’m assuming a vendor saw this thread and decided to try to capitalize.

While I normally would not jump into a thread to comment on another vendor's product, I feel that this requires correction. The Ebay harnesses are wired through directly from plug to plug with approximately 2.5 inches of wire between, with the only (heat sealed) connection between the harness plugs on the single wire for the JB4 connection.

I know this as I purchased a set, due to the substantial cost of shipping your harness to Canada - the approximately 30 dollar surcharge is about 40 dollars Canadian at the current onerous exchange rate, which results in a quite expensive landed price.

I unwrapped the supplied harness wire coverings on the Ebay product 1) to check the build quality, and 2) to apply my own heat-resistant harness tape and covering, matching what I applied to the bare JB4 fuel wires. So I can state this clarification with confidence.

You've done a fine job with what you've built, and I appreciate your efforts - I wish you continued success with your ongoing fabrication/sales. I just needed to set the record straight on this other product.

I won’t debate you. However, I’ve also purchased 3 sets and know exactly what I received. When I inquired to the vendor about the additional bulk, I was explicitly told what he had done and he assured me that there would be no issues.

While there’s a chance that the design has improved, it was not that case 2 months ago when they first popped up on eBay. I still have 2 sets laying around here.

At the end of the day, the community can decide who they wish to support. An eBay vendor who took the idea and looking to turn a profit OR a fellow owner who is doing this in his free time with no profit only for the benefit for the community.

I don’t set the price for shipping. The rates published are what I charge. If there was a cheaper, and more convenient, method of shipping that’s what I would do. Unfortunately, international first class postage has been unavailable for purchase online since earlier this year and it’s inconvenient to go to the post office to buy that postage — therefore Priority Mail is the convenient option.

I wasn't expecting a debate. Whatever this vendor may have been shipping in the past, I'm simply stating that your statement about how they are built is inaccurate, based on the construction method they are shipping now. I wouldn't have posted otherwise.

I'll refrain from any speculation about the other vendor's motives, the origin and genesis of their product, or how they can profitably manufacture, ship to Canada, and still sell at the landed price they do. Before there were any products for sale (yours or others) I looked at buying the needed parts for a DIY inline adapter (I hate piercing wire taps), and I do know it's not economical or practical for me to build a one-off set.

Again, it looks like you are providing a good product for sale to the community, and I wish you good luck with your enterprise! :thumbup:

Got mine, too. Quality.

Put them on during lunch. Wondered why there were 4 sleeves. Didn't realize until after heating the solderless that the sleeve is a little shorter. Looks like it will be okay with one.

Thanks, ecko04! Your work is appreciated!
 
The September shipment is completed. I can add you to the next batch.
Please add me to the next batch and let me know which payment process you prefer. Thanks for your commitment to this.
