What brand/type electrical connectors are used in the 05 Beaver - Monaco?

I have been looking for the brand/type of electrical connectors used in the low-voltage wiring inside the coach.
On the connector body it says "AMP". I looked through the AMP catalog and the closest match seems to be the "DETSCH STAMPED & FORMED"DEUTSCH Stamped & Formed Contacts | TE Connectivity This pin does not appear to have the split post/tip.

or "AMPSEAL 16" line. It's still unclear whether or not that is the style. http://www.te.com/usa-en/product-CAT...=54177%2041620

I would like to get some "pins".

This is a photo a what I'm working with. If anyone knows anything about these let me know. Thanks.

Try Northwest RV Supply in Eugene Or, they might have some connectors, or salvage yards. Allied Electronics has AMP products as do other electronic suppliers.

Hi CountryB; Looks like the Molex could be you best shot, but if not sure give Beaver Coach Sales in Bend Oregon a call. Someone there should be able to answer you question. Good luck

The OP states the pins are made by AMP, different company than Molex. Either should be easy to find.

CountryB-

Monaco used Amp "Universal Mate-N-Lok" connectors, both the original and the "II" (that is, "2") version.

The original and "II" connectors can be mated, but the shells themselves and the pins that are in them are different for the original and "II" versions.

The original shell is a one-piece design. Removing the pins requires a pin removal tool.

The "II" shell is a two-piece design. I believe that's the style shown in your pictures. The pins can be removed by separating the shell pieces.

I buy these parts from Allied Electronics, as they have no minimum order quantity. Here's a link to the Mate-N-Lok connectors at their site. Here's a similar link to the "II" products.

I standardized on the original version so as not to have to keep multiple versions of shells and pins. I bought a pin removal tool.

They are Molex connectors. Pins are available on eBay and Amazon AFAIK. If you don't have the proper crimping tool, soldering is considered the proper technique.

CountryB-

A little more info. The part shown in the picture is a Universal Mate-N-Lok II, part number 770022-1. The Allied Electronics page is here, and the datasheet drawing here. If you want to put new pins in that shell make sure you order Universal Mate-N-Lok II pins, not the "original" Universal Mate-N-Lok pins.

Mark,

I'm trying to understand this. I have a few questions.
1. We have either the AMP version 1 or 2, OR we have the Molex system? Is that correct?
2. I would guess there is some sort of labeling on the connectors?? Otherwise how do you tell?
3. They are NOT interchangeable?

thanks

My Monaco coach uses the Universal Mate-N-Lok II (UMNL2) connectors. By the picture in the first post, so does "CountryB's" coach. Several of the Monaco drawings I have refer to part numbers that are either Universal Mate-N-Lok (UMNL) or UMNL2 parts. I have seen other pictures and threads that lead me to believe Monaco used the UMNL or UMNL2 connectors on multiple coaches from multiple model years.

That said, "your mileage may vary."

Molex connectors can be similar in appearance to the UMNL connectors. Here is a link to a 4x3 Molex connector I have used on a different coach. This Molex connector and the UMNL/UMNL2 connectors are not interchangeable.

The UMNL and UMNL2 shells and pins have the same dimensions. That means you can plug a wired UMNL connector into a wired UMNL2 connector and it will work well.

What is different between the UMNL and UMNL2 series are the shell and pin designs. Thus, you must use UMNL pins with UMNL shells, and UMNL2 pins with UMNL2 shells. Also, the UMNL design requires a pin-removal tool; the UMNL2 design does not require a tool.

You know you have a UMNL2 connector shell when you see it's made of two parts, with a pair of clips to hold the two parts together. It's the split shell that allows you to remove pins without a tool. The drawing to which I lined in post #9 shows this clearly. A UMNL shell is a single-part unit.

For both UMNL and UMNL2, if you see the term "plug" it means a male shell, and the word "cap" means a female shell. Pins also come in male and female, known as "pins" and "sockets," respectively." "CountryB's" pictures are of a 12-position "matrix" plug with (male) pins. "Matrix" means the pin positions are not in a single line. (For example, a 4-position shell may come in 1x4 linear or 2x2 matrix versions). I found the Monaco connectors are usually plugs-with-pins and caps-with-sockets.

UMNL/UMNL2 pins/sockets come in multiple sizes, three of which I found most useful:

10-12 AWG
14-20 AWG
18-24 AWG

A decent crimp tool with a die for uninsulated terminals works well on these pins and sockets.

As I said in my prior post, I've been able to get by with just UMNL parts because I have usually had to build new connectors, rather than modifying UMNL2 connectors.

Now you know about everything I do.

thanks for taking the time to post that.

It is incredibly helpful.

Mike, If you don't have one this will come in handy crimping the connector pins back to the wires. In all the Caterpillar Off Road Equipment I worked around used the Deutsch pin connector systems.
