Overview
The EBX-2208 is the EBX family's dedicated 24 V wiper controller. Where a full BCM such as the EBX-953 or the EBX-954 absorbs wiper drive into the body-control scope, the EBX-2208 is the right tier when the program wants the wiper drive isolated on a small, hard-wired box close to the wiper motor — either because the BCM is already at I/O capacity, or because the program uses a steering-column combination switch that hands the wiper command directly to the wiper motor without going through the BCM.
Electrically the module operates across an 18–32 VDC range with quiescent current ≤ 3 mA. The output stage is dimensioned for direct drive of a commercial-vehicle wiper motor in three speed modes (high-speed, low-speed, intermittent), with park-position feedback closing the loop so the wiper always reverse-parks to the stowed position on switch release. The build is sealed to IP53 (dust-protected, spray-protected) for in-cab placement near the steering column or under the dash.
Integrated functions
- High-speed wiper drive. Two-channel high-speed drive output sized for the wiper-motor high-speed brush.
- Low-speed wiper drive. Two-channel low-speed drive output sized for the wiper-motor low-speed brush.
- Intermittent mode. Programmable wiper-cycle timing — reference profile per the customer combination-switch behaviour and run-time over the IGN-on window.
- Park-position reverse. Park-position feedback from the wiper motor — the controller reverse-parks the wiper to the stowed position on switch release, regardless of where the blade is mid-stroke.
- Switch debouncing. Debounced low-speed / high-speed / intermittent switch inputs (typical 5 – 20 ms debounce) so column-switch contact bounce does not double-fire the drive.
Engineering details
The EBX-2208 occupies a 130 × 99.4 mm footprint (110 mm body width × 90 mm depth, 130 mm over the side mounting ears with two M7 through-holes on the ears) with a 39.5 mm overall height (including the connector profile on the top edge). The harness interface is a single 13-pin housing on the bottom edge of the controller — one mating cycle, one harness drawing per cab.
- Single-housing harness footprint: all power, ground, switch inputs, park feedback and motor drive land on one 13-pin connector
- Two-channel drive per speed: two pins on the bottom row drive the wiper-motor high-speed brush, two pins drive the low-speed brush — doubled-up pin pairs give the harness the cross-section needed for the wiper stall current without needing larger AWG
- Park-position closed-loop: the controller never simply cuts the drive on switch release — it always reverse-parks the blade to the stowed position using the park-position feedback signal from the wiper motor
- Wide IP53 sealing suitable for in-cab installation; specify a sealed-connector variant at quotation if the program requires under-hood IP65 / IP67 placement near the wiper-motor housing
- 3-part PA66-style construction: upper housing, FR-4 PCBA, lower housing — serviceable on the bench with the customer's standard fuse-extractor tooling

Construction
13-pin pin-out reference
The standard build lands all signals on a single 13-pin connector (6 pins top row + 7 pins bottom row). The reference pin-out below documents the channel allocation on the current production build; the customer harness drawing is the final specification at quotation.
| Pin | Function | Type |
|---|---|---|
| 1 | Power ground | Power return |
| 2 | Wiper high-speed drive | Drive output |
| 3 | Wiper high-speed drive | Drive output |
| 4 | Wiper low-speed drive | Drive output |
| 5 | Wiper low-speed drive | Drive output |
| 6 | Power supply (+24 V) | Power |
| 7 | Power ground | Power return |
| 8 | Park-position feedback input (from wiper motor) | Input |
| 9 | Wiper low-speed switch input | Input |
| 10 | Wiper high-speed switch input | Input |

| 12 | NC (reserved) | — |
| 13 | Power supply (+24 V) | Power |
Comparison with other Youlai wiper / BCM modules
The EBX family covers several patterns for wiper drive. The EBX-2208 is the dedicated single-housing 24 V tier:
| Model | System | Pattern | Drive modes | Harness |
|---|---|---|---|---|
| EBX-2208 | 24 V (18–32 VDC) | Dedicated wiper controller | High / Low / Intermittent + park-reverse | 1 × 13-pin |
| EBX-961 | 24 V (18–32 VDC) | Smart wiper controller | Speed + intermittent (per program) | Compact, IP53 |
| EBX-953 | 24 V (18–32 VDC) | Full BCM — wiper inside scope | Speed + intermittent + washer | 9 connector positions |
| EBX-954 | 24 V (18–32 VDC) | Pure-logic BCM — wiper inside scope | Speed + intermittent + washer | 6 connector positions |
The EBX-2208 is the right choice for a program that wants the wiper drive isolated on its own hard-wired ECU close to the wiper motor — particularly on builds where the steering-column combination switch goes straight to the wiper controller without passing through the BCM. For an even smaller smart-wiper controller without the intermittent timing logic exposed, look at EBX-961; to absorb the wiper function into a wider BCM scope, look at EBX-953 or EBX-954.
Manufacturing & testing
Built under IATF 16949 with APQP project planning and a PPAP package available for OEM programmes. Every unit is end-of-line functional-tested before packaging — quiescent current, the high-speed / low-speed / intermittent switch inputs, the wiper drive H-bridge in both speed modes, the park-position feedback loop and the reverse-park behaviour on switch release are all checked. Environmental sealing follows the IP53 reference; specify a sealed-connector variant at quotation if the program requires under-hood IP65 / IP67 placement.
How to ask
The EBX-2208 belongs to the Smart Control Modules family. To request the harness drawing, the wiper-motor stall-current rating, the intermittent timing profile or a PPAP package, use the contact page. These help if you already have them: target vehicle programme, expected annual volume and key technical requirements (wiper motor model, intermittent timing profile, IP rating, connector preference). Drawings welcome.
