Solution decision path
From application problem to connector selection
Use this route to turn an operating condition into technical requirements, suitable product families and a complete RFQ package.
01
Application problem
What operating condition is creating connector risk?
Transmission systems combine module signals, actuator circuits and harsh underbody or powertrain conditions, so connector selection must coordinate pin map, terminal load, sealing, temperature and harness routing.
Define use case
02
Connector requirement
Which technical requirements must be confirmed first?
Interface: TCU, valve body, solenoid, speed sensor and gearbox harness / Circuits: mixed signal, control and actuator loads by pin map / Environment: temperature, vibration, fluid exposure and sealing by location
Check requirements
03
Product route
Which product families should be reviewed for this solution?
18 Pin Automotive ECU Connector / 24 Pin Automotive Control Module Connector / 0.64mm Automotive ECU Terminal

Engineering review
Technical risks to confirm before product selection
These points help buyers understand why connector selection should be reviewed by application, not only by product name or pin count.
Similar housings may use different keying, terminal families or circuit allocation.
Actuator circuits and low-current signals may require different terminal sizes within one system.
Fluid exposure, temperature and vibration requirements depend on the exact gearbox or module location.

Solution FAQ
Can a transmission connector be selected from pin count alone?
No. Keying, terminal load, pin map, sealing, temperature, fluid exposure and the mating interface must also be confirmed.
What should be sent for a TCU connector review?
Send the module or header drawing, pin map, circuit loads, wire sizes, environment requirements and any reference connector or sample.
Need this connection solution reviewed?
Send application, drawing, voltage, current, environment and annual demand. We will match product options and engineering requirements.
