I'll try to make a long story short. The fridge listed in the subject line was purchased used from the lady we bought a house from. Didn't notice at the time the icemaker had been gutted, called her to ask about it and got "it had some problems, so we took it out". First problem I encounter is the wire harness was gone too, I find out most replacement units don't come with a harness. The local appliance parts place finally finds a unit with the right connector to plug into the back of freezer, after initially sending me home with one that didn't fit. I think I'm back in business, but no, the harness is too short! I'm pretty handy with electronics and electricity, so I fixed that by adding a few inches to each of the four wires (I promise I did a good job of this, I know it's not the cause of the problem, been doing stuff like that for over 20 years. Just had to add that, so it's not the first question back to me). Another note, the new maker is the "modular" type from the identification page. And I would guess the fridge to be 5-8 years old.
So now the unit is installed, after a bit, and a number of quick peeks, I catch it in the cycle of rotating the ejector, but no cubes. I figure there was air in the line, and it will just take a few cycles, but after nearly 24 hours, nothing. I know the temp is OK, because I witnessed the maker going through it's cycle at least three or four times. So I begin to troubleshoot.
I guess I better mention this first. The counter guy that found the maker had mentioned that the kit was for a Maytag top freezer model, not my side/side. He made some cryptic remark that he thinks there are some models that require two wires to be swapped in the harness, but he can't remember any more detail than that.
So, back to my troubleshooting. I unplugged the water solenoids and check the coils, they ohm out good. I leave them unhooked, and jumper them straight to 110AC with my "test cord", and I get water flowing into the icemaker. So, I'm pretty sure I'm looking at a wiring issue. I did do a little continuity checking from the connector inside the freezer compartment to the solenoids, but I think some of the readings are misleading because of all the other circuitry, but for what's it worth, here's what I got. The connector in the freezer section is a four pin rectangular connector, mounted vertically. I can't really see the wires that go to it, as it's mounted flush with the back of the freezer interior. The top pin of the connector is chassis ground, that one I'm sure of, it corresponds to a green wire with a yellow stripe in the harness to the maker. 2nd pin from top seems to go the brown wire on the solenoids, this is a brown wire in the wire harness to the maker. The third pin from the top, and the bottom pin gave me some strange readings, both of them read continuity to the other wire on the solenoids, as well as to the AC plug, so I'm not sure what that means. The third and last wire on the harness are white and red. I just realized I forgot to note which of the four in the harness has the temp sensor (that clips to the side of the ice mold), I think it was the white one, but until I look again, I can't say for sure, sorry 'bout that.
So, are the "modular" icemakers a common pinout, and does anyone have that information? And I would need to know the pinout of the connector at the back of the freezer too.
An additional bit of information, the kit I bought was a P/N MA UKI1500AXX, description of "Maycor Top Mount I/M Kit". The sticker under the cover of the icemaker assembly has this number "MMAP106W10122519". The appliance parts place had intially sent me home with a "RIM2000 Kit", it had the right connector on one of the included harnesses (it had MANY), but it had male pins in the connector, and so does the fridge, that was a no-go there!
Sorry to be so long-winded with my post, but I wanted to be sure I covered everything I could think of, hopefully it didn't take you as long to read as it took me to write  and hopefully someone will be able to tell me which wires to swap, or perhaps they feel the I/M I got is not compatible with my fridge. Thanks so much in advance. This forum helped me out so much in the past with a Maytag Neptune washer, I just had to donate to the beer fund, and will probably do that again if I get ice flowing from this sucker!
