About Pinout with Hamza

What this website is

Pinout with Hamza explains car wiring the simple way: pin numbers, wire colours, easy diagrams and trouble codes (DTC), in both English and Urdu.

Factory wiring diagrams are hard to read. We redraw each circuit as our own simple, colour-coded picture and explain step by step how it works and how to test it.

Who it is for

Mechanics, auto electricians, students and car owners who want to understand a fault before paying for a repair.

Accuracy

We check every post carefully, and we mark anything we are not sure about with a “?”. Pin numbers and colours can change between models and years, so always confirm with the service manual for your exact car.
