today i cut my head light harness from the fuse box if i got a new harness would it wire right up to it i have been taking stuff off that i know i will probably use again.
-
Why did you cut it. it will ubolt/unclip off of that.
-
Your talking in the engine compartment? Could have unbolted the connector and removed just the front light harness connector (the middle one)
My 75 two headlight harness mated right up to my new 84 cab's connector.
-
oh i am getting a new dash harness and engine harness so i am covered it was all hack up anyway.
-
today i called american auto wire to ask about a dash harness and they ask me do you have gauges or warning lights and i said i have both but he told me that i have gauges so which one do i have and what is the differences.

If that is your cluster, you have Gauges. I would tell them you have the brake warning light in the bottom right just to let them know.
-
yea it is mine what is the difference in gauges or warning lights
-
Hotrod, The wiring would be different to work a gauge than having a warning lamp come on signaled from a sending unit, just as the sending units themselves are different. Also the placement of the pins on the plug going into the circuit board are different because of the different placement of the warning lights & Brake light, ect. as was mentioned. Lorne
-
ok i understand now how hard would it be to get my warning light to work that is on my cluster
-
If they sell you a factory harness (assuming you are buying a harness that matches the truck with that cluster matching the truck also) it should work.
What year is the truck?
What year is the harness you plan to order for?
What year is that cluster from?
-
my truck is a 78 and i was going to order a harness for a 78 and the cluster i have is from a 77 will it work.
-
that ought to work just fine.
-
76-77 is the same (mech oil sender) is that what the cluster is?
78-up is the same (all electrical)
Are you getting the complete harness?
-
yea i am going to wire my whole truck with american auto wire
-
How much is that going to cost you? If you do that and want to use that cluster, get one for a 77...
Last time I checked a Painless system was cheaper...

and i have 76-77-78's
-
yea it would cost me $449

-
That is for the American Auto?
-
yea it would cost me $400How much is that going to cost you? If you do that and want to use that cluster, get one for a 77...
Last time I checked a Painless system was cheaper...
OUCH
-
i checked painless and it would be 539.89
That is for the American Auto?
-
That is a good deal if it is the complete harness.. Painless normally runs around $500...
I think Autowire terminates them also..
-
are you taking about painless or auto wire which one would be a good deal?
That is a good deal if it is the complete harness.. Painless normally runs around $500...

-
Obviously if the American Autowire is $400 and the Painless is $540, it would be American Autowire.
-
yea i know my wife was confusing me lol

-
well i called the man i got it from and asked him what year the cluster was and he said he thinks that it was a 76 but i thought that he said it was a 77 is there a way to tell what year it is chris oh and he said that 76 77 and 78 is the same but i dont know i am just going to go by what you say
-
He doesn't know what he is talking about if he thinks 76,77 and 78 are the same.
76-77's are specific to those years ONLY. They have a volt meter and mechanical oil pressure gauges, the others are electric.
78-86 have complete electrical gauges.
87-91 have complete electrical gauges. but have different font and VSS for the ECM
73-75 have AMP meter and mechanical oil pressure gauge.
-
mine has 4 wheel lock and chock and fasten seat belts and brake so what could it be could i get a new printed circuit for a 78 and put it on the cluster?

The warning lights don't matter, They are in the speedo (which can be swapped out) and the tach, which should be able to swap out the lenses at the bottom.
What kind of oil pressure gauge do you have? You can't use a 78 circuit with a 76-77 as you would end up swapping all the pins in the connector.
What specifically does the "new" cluster have?
What specifically does the "old" cluster have?
-
could i get a dash harness for a 78 and a new printed circuit for a 78 for the cluster and new gauges for a 78 and make it a true 78 cluster would that work? but here is some pics of what they have but thay look the same to me if you need to know anything else just let me know hope this helps.
the new one
(http://i222.photobucket.com/albums/dd224/74chevy/103_0942.jpg)
this is the old one i dont know what year it is

They both look like 78's. Flip it over and take a pic of them.
-
I see a extra standoff on the top one between the oil pressure and speedo
-
BTW, I am wondering why you are even considering changing clusters as they are identical as far as gauges offered? ???

That's because someone broke it off...
-
the old is broke so that why i had to change and it would never fit right
new one

old one

-
The circuit boards are identical. I think that is what we were trying to find out, right?
-
yea and if i can use the new in my 78

-
Did your old one ever work? If so, it looks like you should have no troubles, then.
-
yes it worked but it is broke

-
Same cluster. 1978-80. You could swap everything over to the housing if you wanted...
-
so both of my clusters are 78-80

-
yes, that is correct.
If it was a 77 cluster, you would see a hole where the oil pressure gauge it for a metal line to connect to.
-
why do i have a hole where my battery gauge is it is on both of them
(http://i222.photobucket.com/albums/dd224/74chevy/103_0987.jpg)
-
An ammeter would have used that hole and the top one would be empty. But the connector would have been + instead of ground. Your whole system's current would be flowing thru the meter. That is why you can't use an ammeter circuit panels with the voltmeters and visa versa AND why so many questions were asked before we told you it would work. sizzle, sizzle.
-
i am just trying to make sure that if i get a new dash harness everything will work

I just re-read my post... It could have been read as a sarcastic response, but I did not mean it that way. You have put a lot of work into your truck, and I want to see you succeed, too.
-
thanks man i have worked hard but i did not take it that way you was just trying to help out

-
so chris all have to do now is get a dash harness for a 78 and it will work
-
Yes, you need a 78-80 harness to go with the cluster.
-
thanks for all your help
