So the alternator was no good in this truck and upon swapping it out either I unplugged it and never saw where or it was already just dangling in there but the black wire marked "LS" on my new alternator doesn't go anywhere. It looks like it's been spliced a few times also.
After some internet digging I found out that goes to the electronic choke but it's way too short to reach up to the carb and I don't know what to plug it to.
So for now it dangles.
Suggestions?

Also, side note, there's a terminal marked ground on the new alternator, should I just go ahead and ground that for kicks or is that not necessary?

 

What year? The voltage is supplied by the alternator, but if you look it up to see what the voltage is there will be a possibility that you could get power to it from somewhere else. I am surprised that your vehicle runs good without it hooked up. The choke opens by that. If you wanted to disconnect it, you could go get a pull choke assembly and control it from the cab of the truck. I used to have one on my 85 and I loved it. I could adjust it as slowly or as quickly as I wanted, and close it partly if I wanted just a little more power.

 

he lives in a warm climate so the choke is probably never fully closed up, but on the back of the carb there is a black round plastic part with a metal clip coming out of the center, if you grab a bag of misc electrical connectors you should find one that will attach to it and then just wire it up. but basically you want a wire off the alternator that provides (i believe 7volts) power only when the vehicle is running. but honestly if your having zero issues without it i wouldnt worry too much, now if you go somewhere it gets into the 40's and stays there all day then you might have issues with startability.

 

Its a 1984.. And yes, I live down in Florida, so I assume it runs fine without choking because its never cold.. Although, in order to get it to idle smoothly, I DO have to put a tiny bit of pressure on the gas for about 15 seconds after starting it.
I cant believe how well this thing runs, its almost 30 years old! I changed all the usuals, plugs, wires, rubber stuff, air.. But I didnt know where the actual connection to the choke was... Thanks to both of you, I actually think I WOULD like a manual choke, theres just some joy to be taken in mechanically controlling old vehicles.. But, until I get that ordered, I'll find a way to get that wire to reach back there from the new alternator.

 

theres a lot of nostalgia built up with the old manual choke, but i think you would be 10 times happier and save a lot of work once you hook up the cable to the electric choke
