Unplugged wiring

First off, I have a 1982 Z28 carb

Well, I was going through looking for the horn because I believe its missing, when i touch the horn wire to any metal in the steering column i get a small spark or whatnot but nothing.
As I was poking around, I saw a few wires and whatnot not doing anything at all. I would like to fully finish this car and was wondering if anyone knows what these do/where to plug them into.
First off, these are all from the driver side pics, here we begin:

the end is cut? not sure what this was for, this is just in front of driver

heres a few things, all without ends, the cord is for block heater tho

not sure what that round thing does, or what this hose (connected to it) is for... and the other end is....

seems to be important, i was guessing it goes by the air filter thingy, so i took it off

i have a haynes manual, it shows its supposed to go there but there doesnt seem to be a place for it... help would be greatly appreciated.
yet theres more:

guessing this was for horn? if it is let me know and I will try to find a horn at my pick-a-part place

Name:  IMG_1069copy.jpg

and this I have no clue at all...


i will appreciate any and all feedback, even the ones :P

Re: Unplugged wiring

I would guess your cruise controll doesnt work.That cable with the long slot on it is for your cruise if i`m not mistaken and it looks like one of those hoses may be a vacume line to your cruise.The cable is supposed to hook to the throttle on the carb but your right I didnt see a place for it,but I could be wrong about it not being there cause I`ve never had a carbed third gen only tpi.Is that an original set up?You may be right about the horn connector.The rest I have no idea.This is just something we have to put up with on theses cars.I have several cannectors that I`m like WTF does that go to.Is your car supposed to have an evap canister.If so,it`s missing and thats what some of that goes to.

Re: Unplugged wiring

thank you for your response
I forgot to mention, but this car is not original, I bought it off a family, where the father owned then son and they put a stroked 383 in it, so I see in one place a wrap of foil around a tube I will work around later as it looks ugly.
thats right, my cruise control does not work and hasnt worked since I got it, neither the horn or radio.
I found there were no speakers so I put them in (wonder why he took them out) and im guessing the horn is not on as I can't find it and cruise I was guessing something is missing, as on the wiper switch I have the ability)
From the picture on the haynes, it is a throttle for the carb and that metal is either broken or switched or wtf :P
The horn there are two ends, both black (ground?) wire not sure why two clips though. Is it just regular clip on?

Sorry but I am new into repairing cars, I just figured I love the oldschool cars and because I needed some fixes and the costs were outrageous, i tried fixing myself (fixed for now radio, steering column, and a few interior things like lights)
evap canister I am not sure, wish I could find out though.
any more help would be fantastic!

edit: oh and if anyone wants more pics I will gladly take and post more just to get help, maybe next time i can make them smaller too :P

Re: Unplugged wiring

I`m pretty sure you are supposed to have an evap canister.About the horn,My car and haynes manual are at home in another town about 65 miles from where I am now.I`ll take alook at it when I get back to her.I am no mechanic myself but I know a whole lot more than I did befire I found this site.Just hang around and do some reading/searching and you`ll learn alot...then you`ll have more questions and realize you know even less than you thought you did

Re: Unplugged wiring

The "Round thing" is the cruise control servo. Rip it out if you dont need it. Like above, that slotted cable is for the cruise.

As for the first pic, it's some sort of vacuum operated switch. Does the car have an auto in it? Maybe it is for the lockup.

Re: Unplugged wiring

ye its an automatic, forgot to mention.
Instead of ripping it out I would love to get it to work.


so, first pic is vacuum for possibly lockup
then we get round thing, 1 end is throttle and other end not sure yet

then the first set of wires is for horn

second set ?!?

now after school im gonna search threads to see if anyone has done these so I can fix it all up.
Thanks for the help, gladly appreciate more if there is any

Re: Unplugged wiring

Second set might be for low windshield washer fluid, depending on if your car has that sensor.
The cruise control might work if you hook up its vacuum source and find a way to connect the throttle cable.

Re: Unplugged wiring

Nope, thats all there is. If you look at the picture of your carb you can even see where it mounts. See the bracket to the right of the picture with the square hole cutout? Stick the cable through there and it will lock. The slotted section fits over the throttle arm somehow. It is slotted so that it will slide and not interfere with normal throttle control.

Re: Unplugged wiring

well, after unplugging whole link cable and puting it through with not much of a problem I have it all hooked up and going to test the cruise control now, only thing thats weird is that when its fully extended, its in middle of the (nut?) but when it contracts it moves it back just enough to open up the intake... might have to play with settings later on. will post pictures in a bit when im back too

Re: Unplugged wiring

alright, i hooked it up and here is what i was mentioning about it not being fully to one side
Name:  IMG_1070.jpg
Views: 20
Size:  111.5 KB

now it did not work, so i unplugged the cruise switch, knowing it was new it should work but you never know, i checked the ohms and when i held SET and moved to R/A it would play with the ohms, so that works

then i checked what i believe is cruise control module, under the dash opposite side of fuse box but still driver side, everything seems attached in the box, though there are 4 wires into a clip that is closed off by some plastic piece that do nothing, piece looks original so im guessing there shouldnt be anything (i can take picture if need be)

so im wondering whats problem.. and looking, the cruise control servo (round thing) is not plugged in to anything? no electrical wires or doesnt seem like any. this seems umm, odd? I plan on taking it off tomorrow and checking thoroughly and we will see, unless it is supposed to be without anything connected.
if anything when I next time go to junk yard i can pick up a servo too.

Re: Unplugged wiring

The servo should have a harness plugged into it, as well as a vacuum line.

As for the cable, that looks pretty good to me.

Re: Unplugged wiring

Looking at your first 2 pictures I would have to guess that those wires and vacuum solenoids are for a the Hood Vents. I'll bet your car used to have functional hood flaps from the factory. Check your VIN and see what the original Engine type was.

Your car also looks to have a duel horn set-up. ALL engine bay harness have only a single "output" wire on it. When duel horns were installed a short "splitter" harness was installed so that each horn has a power wire. (It's grounded to the body ) Be sure to clean all the contact points on the harness and the pins on each horn because they are ALWAYS full of crud.

That carb is a aftermarket carb and doesn't have the proper linkage for a cruise cable. I would disconnect it. You might have no trouble at all with it as it is installed right now - but I wouldn't leave it there ! If you look through the a JEGS or Summit catalog you will fit "kits" that will allow for the installation of a cruise cable. If you leave it installed than the cruise servo would most likely need adjustment in order to compinsate for the improper carb linkage,....... at least - be sure it doesn't effect the gas pedal cable !


Your very last picture is a picture of the Air Conditioning connector to the Compressor. The car must have had AC at one time and was removed at some point in time.


Hope this helps !

Re: Unplugged wiring

if the 8th digit of the VIN is 7, the original engine should have been the LU5 Cross-fire injection. that vacuum switch on the firewall does look like the hood louver solenoid. in one of the pics above, I think I saw the horn. it is mounted inside the fender near the cruise control actuator. also noticed that there is no speedo cable going to or from the cruise module so, it shouldn't be able to function any way, but I agree that you should get the proper throttle adapter for that Edelbrock carb if you keep the cruise control. hope this helps

Re: Unplugged wiring

its H, originally 305 LG4

going right now to take off the cruise link, and you say you may have seen horn, possibly 6th pic behind the cables, could be it going to check, weird it isnt plugged in (but i know my steering wheel center has issues so I took out a center from a pontiac and will just exchange it and get it to work (got it at a junkyard)

Yup I wont play around with cruise until I get adapter.

what to do with the hood louvre solenoid. I am pretty sure my hood is not original as its black primed while car is burgundy.
this is the hood I have on:

thanks for all help, sorry I am fairly new to this all, but I really really appreciate everyones help

EDIT:
well the horns now work, thanks squirted1 i didnt see em cuz they were all dirty :P took off cruise and wrapped it around and tied to the hose for washer fluid, that way I know its not close to anywhere where its too hot. So I am left with A/C which i will have to hide away, then I get the cruise which will probably be just left until I get an adapter and that hose in first picture, not sure what to do with it yet...
Then I want to polish all the the stuff and make it look great =)
you guys are all amazing!

What do you mean no speedo cable going to the module? The module is under the dash and gets the signal electronically from the VSS.

Re: Unplugged wiring

in the second pic of the 1st post shows the old style cruise master. it's supposed to have an electrical connection, a bunch of vacuum lines, and 2 speedo cables(line in from trans, line out to speedo head). Actually looks like parts of both systems are present. 82 used a mix of old and new stuff
