Redarc Tow-pro Switch Insert TPSI-003-B For Holden Colorado, Isuzu D-MAX And Isuzu MU-X

The Redarc Tow-Pro Switch Insert, part number TPSI-003-B, is a switch mounting panel designed for a clean remote head installation in compatible Holden Colorado RG, Isuzu D-MAX and Isuzu MU-X models. It is made to create an OE-looking finish while still maintaining ADR21 compliance, which is important when fitting a Tow-Pro controller into a factory-style interior layout.

This insert installs with a simple push action and is supplied with a drilling template and self-adhesive gaskets to help with a neat fit-up. It is intended for panels up to 7mm thick, so panel thickness is one of the key checks before ordering, especially if the vehicle has been modified or fitted with aftermarket trim pieces.

For D-MAX and MU-X applications, the insert replaces the accessory socket. The product notes also indicate that notching may be required to correct orientation on those vehicles, so it is worth checking the dash layout before installation begins. The unit is sold each, weighs 0.15kg, and carries a two-year warranty.

Application and Buying Notes

Before ordering, confirm the vehicle is one of the listed applications and check the dash opening against the part number TPSI-003-B. The insert is specified for Holden Colorado RG 2012-current, Isuzu D-MAX 2017-current and Isuzu MU-X 2017-current, so model year and series matter as much as the badge on the tailgate.

Panel thickness should also be checked carefully because this switch mounting panel is designed to fit panels up to 7mm thick. If the trim or mounting location is thicker than that, the insert may not seat correctly, even if the vehicle model is otherwise listed.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number TPSI-003-B helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Additional published details for cross-checking include Product Group 2 VOLTAGE CONTROL.

For part number TPSI-003-B, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch mounting panel in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is Two Years. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by checking the vehicle application, dashboard opening and panel thickness, and match the part number TPSI-003-B before purchase. For D-MAX and MU-X models, also confirm whether accessory socket replacement and any required notching will suit the intended installation.
