Page 10-25 of the Aft Fuselage plans involves installing the WH-00057 wiring harness. The instructions and diagrams refer to a grey/purple TP724 wire. We cannot find that wire. I called Vans Tech Support and they said the was no such wire, even though it's in the plans. Before I close everything up I thought I'd check here.

Does anyone know anything about this wire?
 
TP724 is definitely part of my wiring harness running into the aft tail. It breaks off and is part of the ELT install. Just confirmed
that by looking at it.
 
Just looked at my aft fuselage without tail surfaces and I find no Grey/purple wire. This is a March 2022 shipped harness.

The plans say it's grey/purple but it's really just grey (or white - hard to tell). Just wanted to make sure I wasn't missing something. I'll follow the wiring diagram and make sure the wires that come out of the front Molex go to where they are supposed to based on pin # vs. wire color.
 
To be fair my wire looks straight white, but is marked right at the end TP724. It is illustrated on 53-04 figure 3. Part of
the ELT Din connector.
 
Similar issue. Sent email to Vans but haven’t heard anything for several days.

Details:
Page 10-25 (RV-14A), step 4 says to route P725 (WHT/RED) and TP724 (GRY/PRP) wires. Unfortunately my WH-00057 wiring harness doesn’t seem to have those wires (or they’re colored differently).

As you can see in the photos, the WHT/RED was pretty easy to distinguish. However, the subsequent photos show the remainder of the harness ends, none of which seem to be GRY/PRP. By process of elimination, I’m guessing the wires it’s actually referring to are the ones in the second photo containing a GRN and a WHT wire (maaaaybe GRY?), wrapped in a WHT sheath. Is this the TP724 wire the plans refer to?

Looks just like mine, so I would say yes.

Hey All,

TP724 is the 22 AWG shielded wire. This will be the only 22-1 wire in this harness, so you cant mix it up with a different one.

We typically do put a label on that wire, but that must have been missed in this instance - Sorry for the confusion.

I highly recommend that every RV-14 builder using Van's harness system download the WH-00125 harness document on Van's website. This is the master drawing that shows all of the Van's wiring harnesses in the system giving you a better understanding of the big picture.

Interestingly enough the TP724 wire is shown as white on that drawing, so I would bet that the Grey/Purple color is a typo (milspec 22-1 comes as a white wire unless you custom order it) that was corrected on some of their documents but not all.
