BUILD YOUR QUICK START

Make it your installation.

Choose the connector variant as well as the chassis.

01 Choose your device

Swapped engine? Select a swap/custom route and use the donor ECU pinout.

Check engine & mount fitment

Match the labels. A black wire is not always ground.

Count the wires. K-line uses 3. CAN uses 4.

Check the ECU. The chassis alone is not the protocol.

KNOW EVERY CONNECTION

Classic. Five connectors.

V5.5

Read the board, then the table. Pin numbers below follow the source tables. The strips are signal references, not a view into the cable plug. Use PCB labels and moulded pin numbers to orient the connector; the wire side is mirrored.

ONCE YOUR ECU DATA WORKS

Add the extras.

Keep the first connection simple.

GPS module Four wires · 3.3 V
Bosch PST-F1 Revision-specific sensor wiring
MQS harness & direct wiring Keep the original circuit connected

The MQS adapter adds a gauge branch while preserving the original cluster/junction-box circuit. Move one verified terminal at a time according to the harness instructions; restore the original path and lock every terminal.

Shop coverage: E38, E39, E46, E8X and E9X. It does not fit E30 or E36. For direct wiring, use a suitable automotive connection method and secure the loom. Check what was supplied with your order.

FIRST START / QUICK FIXES

A reading is
the first check.

Voltage on screen confirms power.
A live ECU value confirms communication.

Sources & review notes

Revision 04 uses the published Gauge.S wiki, Classic V5.5 and POD V6.1 manufacturing drawings, and the confirmed five/three-connector device distinction.

E53 vehicle pins, the POD PST-F1 harness and firmware-specific GPS/control details still need their stated confirmations. The board artwork is a top-view locator; match the actual revision and connector markings. Printed inserts remain proofs pending a physical fold check.
