Order Tips for FA-DC-MB26 Benz Automotive Diagnostic Cable

1, Please confirm pin assignment before order. Pin assignment is very important for an automotive diagnostic cable. If it is with wrong pin out, it will not work.

2, Please require drawing or specification for confirmation. This is a good way to confirm details of the automotive diagnostic cable. This procedure will avoid the error caused by the product specifications.

3, Connector shape of the auto diagnostic cable is also very important. Just know it is female or male can not ensure it can match with other device. There are many different connector shape in the market. Though they are with same pin number, but the shape may not match.

4, There are type A and type B OBD-II connector. Type A OBD2 connector is with one narrow gap, but type B is with two separate gaps. Type A is for 12V and type B is for 24V vehicles. So in order to avoid compatibility problem and broken by wrong voltage, please confirm connector type for the obd diagnostic cable.

5, As for wire specification of automobile diagnostic cable, it is not the bigger the better. Big wire is with better physical strength and lower resistance. But nowadays, performance of the wire has been improved and as for short automotive diagnostic cable, the wire will not bring much difference. But big wire will increase cost for the auto diagnostic cable and shipping cost.

6, If you need customized obd2 diagnostic cable, MOQ is always required. Generally we do not accept customized features for small order.

7, As for automobile diagnostic cable requires new mold, it always take about one moth to develop the mold, then take several days to test the mold and make new sample. So please allow enough time for new development auto diagnostic cable.
