that melted thing is the connection to the carb choke stove. this carb/vehicle uses alternator output power to feed a choke spring heater element at the plastic cover of the carb on the passenger side of vehicle. with that not connected the vehicle will run like crap , because the choke will always be on and the throttle plate will not fully open.

Is it replaceable
I got one at the scrAP YARD. that was back in 1990. lots to pick from then. cut off old connector soldered in new connector plus some added wire when I cut it off the wreck in the scrap yard.
still on there today. for some reason that connector melted on me also.
I did replace that choke stove heater coil a bit after that because it was getting weak and the vehicle did not want to start correctly when cold in the hot weather. the electricity flow over time makes this occur.
on the olds 307cu engine exhuast gases are used to heat the choke stove. this sytem is much better. lasters 4X as long as the chev electric.
also it does load down the alternator.
to replace the choke stove you need to drill out those rivets. I then used small machine screws to lock in place.
no rivets means some one already replaced this part ,,OEM it was riveted in.

Thats probably the reason my battery is drained after a day or two of not starting. I have yo jump it off

the alternator has a specific output terminal for the choke . should be orange wire.this goes to the choke heater relay coil, the wire goes thru a connector to the relay coil and changes color to brown. with the ignition to on the relay closes then this is connected to the alternator output for the choke.
the red larger alternator wire goes to the battery not the choke relay.
the CH fuse is the choke fuse 20amp.
also the choke fuse also feeds the idle/anti diesel solenoid on the driverside at the throttle control arm/cable location.
the wire to the choke heater is blue on carb. this is from the choke relay contacts. so now with the ignition set to on power is applied to the choke stove on the carb/blue wire. ignition off no power .
if the choke is open not connected then the dash choke light should be on.

j cat you are incorrect. The part shown in the picture is the EGR solenoid. Look at the two vacuum connections on the left side in the first picture, and the missing dust filter on the vent on the right (looks like another vacuum fitting).
The choke heater gets its power from the underhood wiring harness (and thus, the fuse block).

The green plug is a diagnostic connector for the computer. This is what you connect a dwell meter to, in order to adjust the idle air bleed and/or MC solenoid on the carb.

the return side of the choke heater goes to the alternator. the choke fuse feeds the choke stove. I gave all the wiring details / colors . he can check for any defects with what I gave.
that green connector COULD BE the dwell connection . the pin/plastic looks too much like the one going to the choke. also the test pin does not melt. if the wire is blue as I stated, it will be the choke feed wire.
picture is not showing the wire. index finger in the way.
the dwell connector is usually more fwd but this old anything is posssible.
the picture of the EGR solenoid I did not comment on .

It COULD be? You have to be confident about what a picture shows, as I am with my observation. You can't go telling people "this is the wire" and then sit back as he might think it is, plug it in and at in the best case scenario, blow every fuse on his ECM.
I know you're trying to help, but this is pretty serious here.
Here's a hint: The choke lead has a 'female' connector, the pic above very clearly depicts a male connector.

on my screen I can not tell if male or female.
like I stated before the wire to choke is blue. you cannot see the wire color in his hand.
most likely he will not clarify what the wire color is. if he does then this can be determined.
the issue he has is a poor cold start.

Silicon212 you are correct..on both accounts...
I am new here and have seen a lot of poor and wrong info given out so far on alot of different threads.
