Question:

I have a Newmar motorhome with this 7 way connector. It has a rubber plug, but no pin, in slot 4 that supplies the 12 volts to the trailer. Where or how can I get another pin for this connector?

The pins themselves aren't available separately. Your best course of action would be to replace your existing 7-way with one like the # PK11893 you mentioned. The pigtail, part # PK11998 would plug into the back of the replacement connector, and to activate the 12-volt power supply circuit, you'd need to run a length of 10 gauge wire # 10-1-1, which is sold by the foot from the black wire on the pigtail to the positive battery terminal with a 40 amp circuit breaker # 9510 installed inline.

Keep in mind that the wire color codes on the pigtail might be different than what's currently installed on your motorhome, please refer to the color codes listed on the bottom of the product description which I've linked for you.
