Introducing the PLEX PDM-13® — the smallest solid-state Power Distribution Module in motorsport.

Solid-state PDMs aren't a new category. MoTeC, Link, ECUMASTER, HP Electrtonik and others have been shipping them for years, and they've genuinely changed how serious race vehicles are wired. We're not first to this conversation — and we won't pretend otherwise. What we've spent a long time on is what we'd do differently when we joined it.

The PDM-13 is the answer.

The first thing that makes it different is size. 13 high-side outputs, 100 amps of continuous current, in a 215-gram CNC-machined aluminium enclosure measuring 54 × 80 × 34 millimetres. There is no smaller pro-level PDM in the motorsport segment — at any output level. That isn't a vanity spec. It changes what's possible at the installation level. A single PDM-13 can manage the entire electrical system of a motorcycle, where larger PDMs simply don't fit. Across a car or prototype, the small footprint makes distributed multi-unit setups practical: power delivered locally to each zone of the vehicle, harness runs cut dramatically, fault isolation built into the architecture itself. The distributed approach has always been the strongest argument for solid-state power distribution — the PDM-13's size makes it more accessible than it has ever been.

Compact doesn't mean compromised. Advanced thermal engineering maintains consistent performance under load, and vibration-tolerant construction ensures stable operation even in the most demanding environments. The IP67 sealing, CNC-machined enclosure, and operating range from −40 °C to +85 °C are the visible part of that engineering. The thermal and mechanical design behind them is what makes the rest of the spec sheet meaningful.

The second thing is the software. Every output is configurable down to the detail — current limits, electronic fusing, PWM frequency, soft-start ramps, inrush handling, reset behaviour. CAN-FD for high-speed communication. Built-in functional modules for left/right/hazard flashers and multi-speed wipers with stop-position control. An onboard calculation engine for executing logic on the device itself. A preloaded library of CAN protocol templates for major aftermarket ECUs and OEM platforms.

What's distinctive isn't any one of those features. It's that they all configure through PLEX Device Manager 2.0 — the same unified software that drives our dash displays, knock detection systems and boost controllers. One toolchain across the entire range. The teams already running PLEX hardware get the PDM-13 with no new learning curve. Teams new to PLEX get a software environment they can use across every product they buy from us, now and later.

That integration is the part of the PDM-13 we're most proud of. It's the thing that's hardest to deliver, the thing competitors with broader product ranges struggle with, and the thing that we think makes this PDM worth the time we took to bring it to market.

Another little job on this Jaguar R3 today, adapting the fuel wiring from a Bosch 044 to a brushless Protec pump with an external controller.

Very proud to have had a hand in getting many of these absolute titans ready for the Grand Prix de Monaco Historique.

Best of luck to all the drivers and Front Row Racing!

Ecumaster PMU-16 AS: Probably the most flexible option on the market and makes its direct competition look a little silly.

Another steering wheel switch plate, this time for a freshly recommissioned Tyrrell 018. This is the second we've done, and features a Motec D153 display, Shift Light Module and a series of pushbuttons.

This one uses a Lemo F-series connector. I'm a fan of push-pull type connectors for items that are frequently disconnected, particularly in tight spots where unlatching the bayonet of an Autosport can be fiddly.

This 2002 Jaguar R3 from the glorious era of V10 F1 cars needed an unintrusive push-to-talk button adding for the radio. We made a small device that listened to the state of an unused button over CAN, and triggered an opto-isolated output to the radio.

At about the size of a couple of USB sticks, it's small enough to be easily mounted with the compressor and some other bits in the side pod, is featherweight, and meant no modifications to the existing wiring.

The tiny pinky fingernail-sized Deutsch Autosport ASX connectors are fantastic for this kind of work.

This is the second Motec logger retrofit we've done to an R8 LMP, but a little different from the first. This hooks up a C185 display/logger, BR2 lap beacon receiver, GPS receiver, Tire Watch TPMS, four Texense brake temperature sensors, a couple of switches, and CAN comms with the original Bosch Motorsport electronics.

A recommissioned steering wheel switch plate for a Lola/Aston Martin B08/60 LMP1 from yesteryear. Modern switchgear, a tweaked layout, fresh wiring and clearer labels.

The connector on the old Pi/Cosworth display was custom made by Glenair and is unobtanium nowadays. The original connector was reused and terminated to a Deutsch ASDD.

The original switch plate is shown in the last photo.

Just wrapped up a data logging harness for a striking Tyrrell 012.

This uses an Aim Evo 5 logger with sensors for throttle position, oil and coolant temperatures, oil, fuel and brake pressures, and RPM. The expansion connector allows for connecting a GPS receiver, dash display, cameras and anything else that needs adding over time.

All sealed up and built to last with the usual Raychem materials.

November’s shaping up to be very busy indeed. This was a quick turnaround replacement pit to car radio harness for a Kenwood NX-1800 in a Pescarolo 01.
