914 Electric Windshield Washer Pump Conversion, Need Help! Options

[retrofit]

Has anyone successfully completed this project?
I was inspired by a Pelican Parts tech article and now I'm feeling a little over my head.
Need guidance for solving the problems I'm having.
TIA
Allen

Problems:
1. The new 924 switch I have has misbehaved. First, while checking it out it popped its lid! The metal cover plate came loose and shot springs around the kitchen. Put it back together by epoxying the pivot post that the switch handle pivots on. Then the Brown wire lead just fell off one of the riveted on terminals. Had to tediously solder it on.
2. Tech article reads: "you will have 2 extra wires. A Red and Red/brown wire coming from the 924 wiper switch. My switch has a Red and a Brown wire. (Isn't Brown usually ground)
3. Where to tie into the fuse block? Haynes doesn't have a diagram showing the terminals and their numbers and functions. Directions read: "connect one of the two leads from the wiper switch to the fuse block over by the terminal that powers the wiper motor(?). Connect the other lead from the wiper switch to the wire from the pump motor. Tried that taking power from the terminal which powers the radio. When I went to attach the wire to the power terminal I got sparks!! Oh, no.
4. After ilnstalling the turn sig and new wiper switch I turned the ignition on to test and have nothing! No wipers and no turn sigs. Is it ok to test run at this stage of reassembly?
5. Lost the oil press and gen lights-red and green when the key is turned to ignitiion on. Check fuses. Look ok. Blown relay(s).
6. Have two circlips-one large and one small. The large looks lilke it goes over the steering column bearing. Tried it and it fits. Is this right? Where does the small circlip go? Haynes is diagram is vague and nothing in the text like "first this and then that..."
7 Also found one small brass bit (terminal) that may have fallen out of one of the original switches. Checked out the turn sig switch and nothing appeared missing. Hmmmm.

This project is killing me! So far nothing is working as it should and what did work before is now not working.

Where should I begin to make this project a success?
