How quickly will I get access to the wiring diagrams after payment?

Access is activated instantly after a successful payment. A payment receipt and an activation email with a link to the wiring diagrams will be sent to your email.

How long will my access be valid?

Access is activated permanently and is not limited in time, just like if you purchased a physical book.

Where can I find the wiring diagrams I purchased?

In your personal account. To access it, click the user icon in the upper right corner of the website.

What if the wiring diagrams do not match my car model?

This is very rare, but if the diagrams do not match your vehicle, contact us at support@portal-diagnostov.com and attach a few photos of the connector or wiring that does not match. We will issue a refund.
