Azuga Extension Cable for Temp Sensor, 9 ft

At a glance

What the shop says

The Azuga shop lists this as an extension cable for a temperature sensor, 9 feet long, part number HTC-008, at $9.99. Its description says it extends the reach of temperature sensors while passing data reliably. It lists no connector types and no compatible device. The 18 foot version, HTC-008-18, has the same price.

Measure the path, not the distance

The straight line from the probe to the tracker is never the length of the cable. The cable follows panels, edges, frames and corners. Run a piece of string along the exact route you plan to use, mark it, then measure the string. That number, not the one on the tape from the probe to the tracker, decides the part.

• Add enough slack at each end that nothing is pulled tight.
• Allow for any door, hinge or panel that moves. The cable must reach with the panel fully open.
• Leave a service loop near the tracker so it can be removed without cutting ties.

A rule of thumb is to add about a fifth to the string measurement and then round up to the next cable size. That is general practice, not an Azuga figure.

Routing that lasts

• Away from heat. Keep it clear of exhaust, heater lines and engine components.
• Away from moving parts. Steering, pedals, seat rails and tailgate hinges all cut cables over time.
• Clipped, not taped. Use clips or ties at regular points so the cable cannot swing.
• Drip loops at connectors. A small downward loop before a connector keeps water from running into it.

The chaining question

If nine feet is not enough, it is tempting to join two extensions. Azuga does not say whether chaining is supported, how many cables can be joined, or whether the sensor reading changes with total length. Until Azuga says so in writing, we would buy the single cable that is long enough, which is the 18 foot version, rather than joining two nines.

After it is in

1. Check the portal shows a reading from the probe.
2. Move the cable gently along its path and watch the reading. A reading that drops out when the cable moves points to a loose connector.
3. Photograph the route for the install record.

Where to go next

Questions we get

Is 9 feet enough for a trailer?

It depends on where the probe and tracker sit. Measure your own route with string. Azuga does not say how long a total run can be, so do not assume.

Can I join two 9 foot cables?

Azuga does not say it is supported. The 18 foot cable costs the same $9.99 as the 9 foot one as of 2026-10-21, so a single longer cable is the cleaner choice.

Does an extension change the reading?

Azuga has not published anything on this. Test the reading with a trusted thermometer after you install it.
