HJ–WB Holden GTS RetroTech Dash Kit · SAAS Series 3

Want the iconic GTS dash in your HJ, HX, HZ or WB Holden without hunting down original GTS instruments? The Emdawg RetroTech HJWBGTSS3 GTS Dash Kit fills in every missing piece of a non-GTS to GTS dash conversion, and gives you accurate, modern SAAS Muscle Series 3 electronic gauges with a classic analogue look.

New reproduction GTS fascias are available from Rare Spares and other suppliers, but they don't come with gauges, indicator lights or warning light globes. This kit supplies them, including our pilot light cluster that brings back the GTS turn signal, high beam and hand brake lights. It screws straight into the clock hole, so there's no cutting of your new fascia.

✅ Vehicle Fitment

• HJ, HX, HZ and WB Holden fitted with a GTS dash fascia (original or reproduction)
• Made for Kingswood (non-GTS) to GTS dash conversions
• GTS dash fascia not included

✅ What's in the Kit

• 3D-printed GTS gauge pods: left and right main gauge pods plus the 4-gauge auxiliary pod, printed in high-temperature engineering-grade filament
• SAAS Muscle Series 3 gauges, pre-installed: 80mm speedo and tacho, 52mm fuel, oil pressure, water temp and volts
• Lower auxiliary gauge bezels already machined for clearance
• SAAS oil pressure and water temp senders
• Auxiliary gauge cluster pre-wired to 3 Deutsch DT plugs: power and ground, sensors, and programming buttons
• Pilot light cluster (clock delete), pre-wired with four 12V 14mm LED pilot lights: left and right indicators, high beam and hand brake
• Brake fail and battery charge warning light sockets with T5 LED globes. The battery light has a built-in resistor so the alternator charge circuit works properly
• Car-side Deutsch DT connectors for a clean install that's easy to remove and service
• All-new mounting brackets and screws
• Full printed installation manual, including Kingswood-to-GTS wiring instructions

✅ GTS Indicator & Warning Lights, No Cutting

The original GTS speedo and tacho have the turn signals and high beam built in, but the SAAS gauges don't. Our pilot light cluster puts them back in the original clock position, where they're easy to see even with a sports steering wheel. If your car used a single combined "brake fail / hand brake" light, the kit lets you split them into separate warning lights.

✅ SAAS Muscle Series 3 Gauge Features

• Classic analogue styling with red needles and bright aluminium bezels
• Accurate electronic speedo, tacho, oil pressure and water temp, a big step up from tired factory gauges
• Multifunction display: odometer, shift light, overspeed alert, low fuel warning and more
• 10 LED backlight colours: red, green, blue, purple, white, amber, pink, ice blue, orange and aqua
• Separate day and night brightness settings
• Remote programming buttons for easy setup and calibration
• Great for stock rebuilds, modified engines and LS or other modern drivetrain swaps

✅ Speedometer: VSS, Converter or GPS

The SAAS speedo is electronic. If your transmission has a VSS output, connect it directly. If it still runs a speedo cable, choose a Speedometer input interface above:

• SAAS GPS sensor & antenna: works with any transmission, no calibration needed
• ESA-01: cable-to-pulse converter for GM transmissions (Powerglide, TH350, TH400)
• ESA-01 + ESA-02: converter plus cable adapter for Holden transmissions (Trimatic, M20, M21)

⚠️ Please check your local regulations regarding GPS speed signals.

✅ Installation

• Some clearance work is needed: a few millimetres are trimmed from the two lower mounting posts on the cluster's aluminium mount
• Wiring required: ignition, constant 12V, ground, instrument lights, fuel, tacho and speedo signals, oil and temp senders, and the pilot lights
• Tools: basic hand tools, a multimeter, soldering or crimp tools, wire strippers and a Deutsch crimp tool (or choose the pre-crimped Deutsch tails option). A die grinder or Dremel is handy for the clearance work
• The manual covers removing the old cluster, the clearance work, wiring from a Kingswood dash, start-up checks and troubleshooting

You'll need to be confident removing the instrument cluster and doing automotive wiring. If unsure, have an auto electrician fit it.
