First of all, I am getting all my info from THIS THREAD. I am just bringing this info here since people might want some info on it.
The reason for this upgrade is to increase the amps of the alternator while still having a parts store replacement option. Stock was only 80 amps and these are 140 amps. Might be cheaper than having your alternator rebuilt for higher amps, but this one can be found at most auto parts stores. These came on many different vehicles, but I used the 1996 Cadillac Fleetwood as the search vehicle at the parts store.
Some things you'll need.
1) CS144 Alternator (Obviously)
2) Either a GM alternator Pigtail to splice to stock harness, or an adapter (I didn't want to wait for shipping)
3) Either some butt connectors or ability to solder. (I chose to solder and heat shrink over it)
4) Either make a spacer or stack some washers to be roughly .250". (I made a spacer out of an old bushing sleeve)
Now the wiring.
The GM pigtails all have differnt wiring colors depending on which one you get, but the connectors are labelled by letters to make it easy. S, F, L, P.
S = Sense - This is the thickest wire, and connects to the WHITE wire on the Toyota Harness
F = Field/Ignition - This connects to the RED wire on the Toyota Harness.
L = Lamp - This connects to the Yellow Wire on the Toyota Harness.
P = Stator - This doesn't get used and most harnesses don't even have a wire for this.
The main power wire has some small tabs on the terminal end that need to be trimmed off to fit. I just used some Dykes (Diagonal Pliers)
When installing the alternator, you need to put the spacer or washers at the back of the alternator bracket so the alternator sits all the way forward. The GM alternator uses a 6 groove pulley while stock is only a 4 groove pulley. I put the belt on the furthest forward grooves.
I really suck and didn't take any pictures of the process, but it is fairly straight forward. Here are some google pics for you.
