Hello members,

I have a question regarding the front wiring harness that runs from the driver side firewall to the radiator.

I have a new front harness that has the connection for the alternator, horn relay and voltage regulator.

Link Front Harness:

Front Harness

However, my truck has a LEECE NEVILLE 2500 JB alternator with integrated regulator installed. There is nothing on it except a plus and minus symbol (see pictures).

I'm having a hard time with the alternator wiring and the non-existent voltage regulator. I also don't know how to connect the alternator even with ammeter. Everything was out when I bought it.
Is there any way to bridge this quad connector (see pictures)?
Does that make sense?

Or is it better to buy a new front harness?
Which one comes into consideration for my alternator and the rest?

I would be very happy about tips or great wiring diagrams :-)
Keep the trucks running!

Greetings Brian
