    Lights and horn turn off truck

    A little background info always helps. For example: Did this condition develop gradually - getting worse over time - or did you just wake up one day and it suddenly existed? If it began one day and has been that way ever since, were any repairs/modifications done immediately prior to that...

    WTH Are These Wires

    Any time I see a BLK/WHT pair go under the carpet, through the TC shifter and then down through the floor, I assume they are associated with the shifter backlighting and 4WD indicator lamp. That ORN/WHT pair is generally supplying the dome lighting circuit. Those other two cut wires IDK (I'm...

    Front brake hoses

    Only the JB 1&3 systems have 1" rotors in the front and both of those systems use 11" drums for the rears:

    Electric Choke Power Source??

    That's oil pressure sender. Only used when equipped with a gauge package. There is just one terminal - that a TAN wire connects to:

    Replacement tail light sockets

    Wait.. the whole harness? Where do you see these at? And I would have guessed the things were hard wired from the front of the truck to those sockets. Where do they go from one connector to the other? Possibly did this for different length trucks? The 3 branches lines to the individual light...

    Under hood wiring - Part 1

    That plugs into the EGR bleed solenoid - part of the TCC control circuit.

    Engine Cranks Then Doesn't - Ignition?

    This assumes a fully charged battery, an engine that is not seized, and that both battery cables are good (i.e. no shorts to ground, copper conductors are in good condition and properly connected to the fittings at both ends). If moving the ignition switch to the START position can cause such...

    Acc fuse

    A trouble shooting hint: The cigarette lighter is hard wired to the fuse block but the power lead for the dome light circuit is a plug -in type. You might want to just unplug the dome lights and see if the problem goes away. If it does, you'll know where to start looking.

    Under hood wiring - Part 1

    Without images it's hard to visualize what you are dealing with. But just in general: There are two PNK leads coming through the bulkhead connector. One is power from the ignition switch to the B+ terminal on the ignition coil. That wire transits the connector at the 2nd row from the top/3rd...

    Different masters

    Haaa! Chengny just stands for Chief Engineer Overseas New York. That's how they abbreviated the position on the payroll list. My avatar is the O/S New York. It's long gone, we're all shaving with it now.

    Power lock killing battery, help?

    Sometimes the ground fault is intermittent. After the circuit that is causing the drain has been identified, the specific location of the short still needs to be found. This is often done by shaking/pulling/twisting the associated wiring in an attempt to intentionally cause the short. Depending...

    Replacement tail light sockets

    Those sockets look to be the style used on trucks later than yours. But they all use the same twist-lock mounting style. The only difference is that the earlier sockets had the wiring at a 90 degree angle. If you want to keep the style you have now, search for these P/N's: 1...

    Different masters

    You mean Matthew 6:24 "No man can serve masters, either he will love one and hate the other....." The two masters does not refer to people, but rather wealth and spiritual well being. Philosophical enough? On the leaking master - and I am no expert on this - but I think that the pedal rod...

    Intermittent wipers

    Yeah weird, huh? Jason, if you check the ECM for stored Digital Trouble Codes, that might give you a hint as to what is going on. Even thought the SES (Service Engine Soon) light goes out after 10 seconds after an intermittent fault, the associated DTC is stored in the ECM's memory. Any stored...

    Underhood lighting

    Yeah, that's a tach. Like Denis suggested, it's mounted there for when I'm tuning a carburetor or adjusting ignition timing.

    They were really nice and I used them a lot.

    Rejuvenate stainless steel?

    That's not hardly stainless steel. As you found out, the factory trim is a very thin coating over a plastic substrate - it's not able to be restored. Once it is oxidized, there is nothing you can do to save it. Try one of these maybe. It's a brushed aluminum overlay/insert. Comes with a 3M peel...

    Underhood lighting

    Maybe something like this? I had a pair of backup par lights that came off a plow truck sander. They were just sitting on the shelf for a few years so I put them to good use.

    How to tell if you have a bad wiper motor or if its electrical??

    Didn't we work on this same issue a few years ago? IIRC you were going to get a new motor. Anyway, first check is for a mechanical overload condition. While doing these steps, keep in mind that this advice is all very subjective: 1. Just get the wiper blades off the glass. Do this by pulling...

    Power lock killing battery, help?

    The power locks and power windows are two entirely separate circuits. They do run along side each other, but that's as far as it goes. Power for the windows is supplied on a PNK wire that plugs into one of the two sockets in the fuse block that is labeled WDO. But that's beside the point...
