Battery Leads

[Smith]

Just wanting to double check but where should all my leads be going and how many. Looking at my truck it appears I may be missing some.
Thanks

Two main leads. Both would be black if your truck was stock. Since your electrical system has been modified, the positive cable is most likely red.

One (the positive cable) is clamped to the battery positive post. It goes straight from the battery to the big stud on the starter solenoid - the stud is labeled "B". This cable is made of heavy gauge wire to provide a high amperage flow rate to the starter for engine cranking. (There are two other leads that are attached to the "B" stud. The fact that they are in contact with main cable effectively causes them to be spliced - in a schematical sense - to the battery's positive terminal. They are used to feed the rest of the truck's electrical system.)

The other main lead is the ground (negative) cable. Almost always black. One end is clamped to the battery's negative post. The factory routing was straight from the battery negative post over to a threaded hole on the alternator bracket. It is securely fastened to the alternator bracket with a large ring terminal/bolt. (Generally the negative cable has one branch line. It's primary function is to provide a good direct ground path for the forward lighting/horn circuits. If it still exists, that branch wire normally splits off from the main ground wire right near the battery clamp. It is routed straight to the radiator support frame and is connected to the frame at it's termination - again, usually with a large ring terminal/bolt.)

Thank you sir, looks like im not missing anything. Its just so simple that i thought I had an issue lol. Ive still gotta track down a few loose connections and see what they did or should go to. I know some was part of the now disected A/C system. Specifically there a tube that comes out of the firewall that runs with a plug that splits out. Ill have to get some picks and post them up

That tube that passes through the firewall is the vacuum supply to the selector portion of the HVAC control system (controls where the air is directed). The two tubes that extend outward from the "plug that splits out" (more commonly known as a "tee") connect as below:

The image shows an inline engine. With a V-8, the fitting that you can tap into for full manifold vacuum should be behind the carburetor.

The tube in that diagram is on the wrong side, The tube im talking about comes out on the drivers side close to where the throttle cable pokes through

 

[Smith]

Looking closer, that comes from manifold vacuum, T's and then splits to both the driver and passengers side?

Its for your cruise control. Its a vacuum hose
