Hi guys. I’m going to replace a number of the IDC connectors in my EBD with molex style.

A number of the IDC wires loop through the connectors. These wires must be daisy chained and continue on elsewhere.

How do I add a pin style connector on the end of the wire and handle the other side of the wire that continues on?

Does this make sense?

Quoted from RussMyers:

Put 2 wire ends into one crimped pin.
Have done this many times, esp rebuilding GI connectors on games like T2.

Thank you Russ. I get what you you are saying. How can I fit two wire ends into one crimped pin. Aren’t the molex pins size dependent on the wire gauge. Will the crimp fit around the insulation of both wires. ?

Quoted from heni1977:

I would suggest a ratcheting crimper.

Definitely getting one. I have crimpers without and know that the job will be better with.

Quoted from vid1900:

Often 2 sizes of female crimp connectors are available.
Maybe like 22ga and 18ga.
So use the larger gauge (18ga) if you are crimping 2 wires in the same contact.
Molex does not officially rate those crimps for 2 wires, but I've done it many times.
Crash course in crimping:

Thank you vid and everyone.

I have some crimp contacts rated for 18. I will see if that works.
