Default Custom Firewall Engine Harness Connector/Bulkhead

Like many of the products we offer develop or sell, it starts as something we'd use ourselves. Based on feedback this is something we would consider offering.

During the recent engine bay remodeling of the Fab9 NB, we've decided it's time to take wire management to another level with a firewall harness bulkhead. The engine was removed 5 times last season and it would have been brilliant to keep everything in tact and simply disconnect all of the wiring at once.

We're considering a quick and easy package to simplify this process for those of you who might be interested in a solution like this.

These connectors are very high quality, weather tight and easy to use.

Kits will include the following:
1x 1.5" Female 32 position firewall bulkhead mount
1x 1.5" Male 32 position engine side connector
40x Female crimp pins
40x Male crimp pins
1x Template for mounting

(Two assemblies shown here - one connected, one separated)


Pricing will start at $118 and may change based on interest.

Interested. How many cycles of engagement and disengagement are these connectors rated for?

So this is just socket, plug, terminals, and a template? Is there something specific you're bringing to the table that I cant buy somewhere else?

No, we didn't reinvent anything here. Just a convenient way of ordering a package that we know works. If we don't find it appealing to anyone we simply wont carry it but personally I would have bought this much sooner had someone packaged it with all the right components under one part number.

Cool. It does make it a lot more convenient. Are you considering also carrying a high amp connector for the starter/alternator/main power connection as well.

Tempting. Who's connectors are they, and can we upgrade to solid pins?

I believe it's as follows: 4x 12ga wires for power and 28x 14-22ga wires.

Do you happen to have any installed pics? So for the full treatment one would need to purchase two of these (one for pass side and one for drivers side)? Is this crimp tool anything special, or notably pricey?

Looks to be a barrel crimp tool. You can find them on Amazon/Ebay. They'll probably run from pretty cheap to refinance the house expensive. If you have a decent set of crimpers with replaceable jaws you can buy good jaws for about $30.

Edit: Not from exhaustive comparison testing, but my preference so far has been the Paladin/Greenlee 8000 series frame. They work well. That said, the barrel crimp tools FAB proposes are half the set of just the jaws. Pretty hard to argue with.

Right - the crimp tool should be considered when looking at this type of wiring. We did some homework and this tool is VERY affordable ($15) and does a great job.

WOW. Serious looking connector. Nice job!

And to add my two cents, I'm quite fond of this Hozan crimper. It's not cheap, but it works extremely well. I've crimped a few thousand connectors with it.

Definitely going this route for the next project. It's a good opportunity to shorten the ECU harness as well for the 1.8s
