wiring stock temp gauge separate ?

[blazer2007]

I need to wire my stock temp gauge separate from the circuit board.There are no markings which is pos. but I think the bottom brass stud is pos. and the the top brass one is sender which has the ceramic and the sliver stud would be pos.

That might get you in trouble.




ignore the add resistor advice. It is for gauges that read too hot.

sorry forgot to say is a 84 style gauge and has only 3 studs.

I don,t see why I could get in trouble,all I,m doing is changing from the circuit board wires to my own. The reason I,m doing this I changed from aftermarket gauges to stock but the temp sending unit wire is wrapped up nice and neat in the harness going to the starter and would be easier to make my own wires than take the harness all apart.

Well you threw me a curve with this one. I thought you were talking about a 67-72 gauge.
As you can see the bottom silver post is grounded to the cluster and you stated that you thought was Pos. Which is why I said you might get into trouble.

If you ran a positive wire into a grounded post then you'd have a short and trouble.

So what cluster do you have? the 67 to 72s were the same and the 73 to 87s were about the same. If you have an 84 cluster you can just follow the circuit board wires to the gauge to see which is positive and which is the sender for your 84 gauge.

You might be able to get a better answer on the 84 truck forums, but if you use an ohm meter. and check continuity then you can tell which post is the ground post for the gauge.

Most all the gauges use a green wire for the sender to the cluster plug and a pink wire to the power (pos) post. I looked but I didn't find a circuit diagram or temp gauge that showed the back with the correct wiring. I will keep checking because I am curious.

Ok thanks I will take a pic of the gauge.Sorry about the curve,I always think everyone knows what I,m working on.

I don,t know what cluster I have,I,ve collected about 4 of them

vette vet - I like the new and improved imagery you're using for us!

This is the 67/72 cluster.




And this is a newer model but I don't remember the year(s).

Here's a handy thread that will save you time and let everyone know what your details are. I.E. The year, style, engine, trans, and anything else you might want to list.

well I made a mistake,I will get my poop in a group and try and do a better thread for my problem . I ended up working 7 days a week for the last 6 months and in a hurry. I try to ask questions with out much thought of what I,m typing.
