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):

You can remove it and verify that the gauges still light up.

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)?

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! ;)

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
