The importance of accurately identifying connectors appears to be misunderstood by many. Allow me to provide a more comprehensive explanation:
When you require an installation drawing for a vehicle, it is crucial to provide us with the specific connector type found in your vehicle. We have invested significant time and effort into organizing numerous installation drawings based on their corresponding connector types, resulting in a wide range of schematics.
If someone requests a drawing for a “Toyota 1KZ,” it means we must undertake a thorough search through multiple directories, diligently opening each drawing to determine if it matches the given description. However, even if we find a drawing that aligns with the description, it may not necessarily be the correct one. This is due to the fact that many engines with the same engine type utilize different model ECU.
To streamline the process, the connector type plays a vital role. If you are planning to install a Unichip in your vehicle, it is essential to examine the ECU connectors and take note of the number of connectors and the rows of pins they possess.
The connector format is represented as follows: for instance, “3×4” indicates three connectors, each with four rows of pins. In cases where connectors have varying numbers of rows, we prioritize the connector with the most rows. Additionally, if the ECU has an empty position for a connector (as observed in certain Honda models), we consider the vacant slot as a connector as well.
Once you determine the connector type for your vehicle, locating the correct schematic becomes more straightforward. Even if the vehicle’s description does not perfectly match, there is a high probability that the connections will be correct for your vehicle if it utilizes the same ECU.
