Clarification: You don't have to spoon with me under the console. You can perch yourself on a chair and snag brewskis out of the cooler for yourself and I, dish out thoughtful advice, tell me what I'm doing wrong, or just provide emotional support.
Or, tell me I'm an idiot and should have never started this damn project.
OK, you're an Idiot!
Regardless, I promise we won't have to get closer than necessary.

Also, I started piecing together some mysteries last night:
1) The three wires running to the back of the boat (green, blue and purple) were for the old hydraulics. Thinking I could just splice them into the new motor's extra tilt/trim wires to get my bow toggle switch working, I did that. Tried every conceivable configuration, however, and nada. Hmmm...bad toggle, perhaps?
Do you have an ohm meter? Put one lead on each side of the switch and see if the needle moves when you flip the switch. If it doesn't move at all switch is fubar.Put one lead on one end of each tilt/trim wire and the other at the other end of the wire that way you can check each wire and find the one(s) that don't work.
2) An orange wire running to one of the two "Acc." fuzes winds up in the bow of the boat with its corresponding negative cable. So I have the ability to hook up another depth finder if I want. This is plausible, as I have a trolling motor with a ducer built in. All I need to do is find the appropriate coupler to marry it to my old extra Eagle and we're in "bid-ness" as the kids say.
Get your meter and see if you have power and ground working at the end of the wire, If not woek your way back until you find the short.
3) My gas gauge does not work, and I can't figure out why. My inkling is that it might have worked before I replaced the old tachomter, and one of the wires that kept the entire gauge cluster in tandem that I took off made it inoperable. Or it hasn't worked for a long time and I just didn't know it. Another mystery...
Get your meter again and use the ohm part to see if the sender in the tank is working. If nothing happens pull the sender and see if it works outside the tank. Sometimes the floats fill up and they quit working.
4) After a thorough investigation, I have just one internal light for my boat. One. Yet the switch has no less than 8 wires running to it. Why the hell one light with two wires going to it somehow multiplies into 8 at the switch is mind boggling. Maybe during all this time they bred and reproduced while in storage?
Are the wires grounds or power? Use your nifty little meter to find out. Once you know that you can trace them as you work on the rest. How many lights does your boat have? Do all of them have power going to them? Are the grounds ok?
5) I did successfully remove some old wires for the old boat that I'd forgotten about, thus decluttering the mess by the slightest amount. Progress.
Awesome rip and tear is a good thing!
