I'm going to take a stab and say the OP is putting their original text into a translator to reprint it here in English?

...at least I hope that's the case....

he wants a drawing for a CF7 electrical wiring. probably for a control box...take it from there Chet

If any of you men have a detailed drawing of the P-N 27 pin MU plugs, I am also searching for that info. I need a blueprint for it, so it can be recreated in a smaller size and still be 100% accurate, so it needs to be quality accurate info. Thanks!

The old 3 MU a 2-4 of 2-4 a why to of total 4 engines pull a the a line. The CF7 will a the 3 MU scrap the wires do a MU 27 to CF7 a Loco's did via is the couple will a new to loco.

This is 6-5 a draw a E-mail a attachment.

The new 27 MU a 5-7 a between.

The NEW a is at EMD,GE a wire at to 27 MU like a loco at factory a need.

following this the 2751 was a santa fe unit which would be now on the York Railway as 1500, the CF7 is a modification of a standard F7 unit. There may have been electrical reconfigurations for the MU. What it sounds like our friend here is a shop man on the York looking to do repair/modification or find some matching electrical to do some repairs, they have GP7s there, but the mods may make the CF7's incompatible with the older Geeps. A shout to BNSF (look for the Santa Fe shops that did this conversion in their Cleburne Texas shops). You would wonder if technical info would also get moved with the engines thru their selling for the new owners shop purposes.

I'm going to take a WILD guess here, and suggest that "3 pin" refers to the obsolete EMD "field loop" jumpers for dynamic braking.

As for what the actual question was, I have no idea............

This gentleman asked some similar questions on another forum some time ago. I directed him to the wiring diagrams that were published in the CF-7 book, but apparently that wasn't what he was looking for. I think at the time he was looking for details of a particular junction box or panel. I believe he is with one of the museums out west, and not with Yorkrail. And only the first CF-7 had DB; that unit is no longer around, so the field loop explanation may not apply. With the exception of B- on pin 19, the MU followed standard AAR recommendations, IIRC.

The CF-7s were wired to be very similar to a GP-7, as opposed to the F units from whence they came. No field shunting, and the 'teaser' excitation when in 'switching' mode- ATSF used them for switching and local power, not so much as road units, so copying the GP-7 electrically was entirely appropriate,

Not much help here, I will admit...

APTA standards for 27-pin receptacle wiring assignment:

http://www.apta.com/resources/standards ... 017-99.pdf

The identity chart is on page 14 of 28. This of course shows a "full feature" pin assignment as used on a passenger locomotive, the typical freight locomotive has fewer features.

If the locomotive that is the subject of the question is in fact an operable locomotive on a G&W subsidiary, I am surprised to see this on RYPN. The G&W has/had a number of CF7 units, and the best technical support talent for them at this point is probably right within the company.
