Product ID assistance please

If you posted a picture it would be much more help than the label off the chip.  However, I suspect what you have is the Lionel LCRU2.

Plenty of late 90's wiring diagrams in the Lionel Parts Lists & Diagrams database of how to wire this board.

John, See below.  What would be the proper search term to bring up the diagram?  I tried the numbers on the chip, several combinations of TMCC and pullmor with no results.  I did find an image online that is a likely candidate with a diagram but would feel better about this if the source was lionel or someone who works on these critters.   Henry

Here's a typical wiring diagram, click on the graphic to enlarge it.

Thanks John, that is a better representation than the one that came up with google.   Best part is this is a single motored F3, so my task will be a bit less complicated.

The place to look for stuff like this is in the Lionel Service Manuals pages.  Just click on the drop down for the Product Supplements and click the Download button to download them.  They come in PDF form, and I've saved all of them on my local storage so I have instant access.

An incredibly useful index is also available, the Supplement Index for Lionel.pdf, this allows you to search on a product number and find the volume it's in.

The volumes you'd be looking in for LCRU2 equipped locomotives are the late 90's models.

John, found that, couldn't figure out which one had the info I needed, looked a bit overwhelming to D/L all of them.  Your diagram was perfect, used an editor to take out the second motor and electro couplers since that is not what I will be dealing with, now the diagram fits my application better.  The index will be D/Led and perused at a later date.  thanks again  H
