The new fuel gauge doesn't have a post for the light wires, but a spade terminal. I should probably use a double male, single female connector...splicing the gauge wires to one, and leaving the switch wire as a single?

I don't understand your question.... The gauge gets a switched positive from the ign switch OR a toggle if you prefer, the. It is grounded through the sending unit which is then grounded to bat neg.
Then the light for the gauge gets wired.... Often but not always the light has a switched positive and a constant ground

That wire you have labeled as "to switch (I thought it was black)" is not FOR the fuel gauge... It it most either taking power from that circuit (which spans the lighti circuits of ALL of your gauges) and using it elsewhere OR supplying power to turn on the lights.... You can remove it and verify that the gauges still light up.

On the gauge in your picture the black and red wires at the bottom almost definately are routed to the sending unit... Red is fuel level and black grounds to one o the screws mounting the sender.

A yellow wire at the tank does not belong there... The only other wire that should be there would be a green bonding wire.... Would connect to fill port, tank, and engine block along with any other major metal component or thru hull hardware.

I need to go from one post (on old gauge) to one spade for three wires. This is what I thought I should do (let me know if I'll blow it up instead):

Ohhhh, it's supplying the entire chain! *doh*

I'm clear with that!

I've been know to mess up elementary colors on occasion! I'll double check to see if it's green, but it looks VERY yellow...maybe from old age (not me, the wire)?

[smokeonthewater]

No don't splice... Move the wires to a different gauge so only one goes to the spade

As long as all are connected ur gtg

Gotcha! Simple enough!

That Red wire has been replaced. Normally it would be pink from the sending unit. When the pink wire ages, it can look orange. Does the red go to the sending unit or is it spliced somewhere to the one you think is yellow? Does the yellow connect to the center of the sending unit?

Its best not to use a red wire for that because it causes confusion since red is usually +12v supply(unswitched). Once people start "fixing" wiring, they tend to buy a spool of red and a spool of black and thoroughly confuse future owners....I will admit to nothing! ;)

[phatdaddy]

or one spool of red, run two wires and put a piece of black tape on each end of the neg wire

i also will admit to nothing
