    Trailer wiring on a 77 K5? How do I do that?

    Crap, I took a screen shot of that exact part, but forgot to share it. That solves part of the no cutting trailer harness issue, the OP wants a 7 pin plug.

    please recommend a transmission dipstick that isn’t junk.

    Last time I needed a dipstick I ordered one from summit. It was around 45 bucks, and didn’t use those junk orings. The boot type seals are MUCH more forgiving.

    Trailer wiring on a 77 K5? How do I do that?

    To put a 7 way trailer plug on that is going to take some minor wiring. I don’t think they ever offered a factory tow package with 7 pin trailer plugs. If the taillight harness is intact, cutting it would be a last resort. And if you do cut it, DO NOT USE CHEAP BUTT CONNECTORS!! Use good...

    1985 C20: Carb not getting fuel

    I have no clue how much fuel a Q-Jet float bowl will actually hold. I’m guessing a 1/4 cup or so.

    1985 C20: Carb not getting fuel

    Fill the float bowl with fuel. Try and start it. With the float bowl full, it should run long enough to pull fuel from the tank. If not, check the fuel lines. Make sure you don’t have one kinked, or corroded.

    I wondered the same thing!!!

    Tq converter for 5.3 ls swap in a 700r4

    I agree. Seems counter productive to upgrade to a modern engine and give it a lobotomy with a carb. Especially considering how expensive those ignition computers can be, they aren’t much cheaper than a pcm to do everything.

    Instrument cluster questions on new build

    There are different sending units based on gauge readings. Meaning a gauge that reads to 60psi, requires a 60psi sending unit. I ran into this years ago with a Grand Prix I had. The factory gauge registered to 80, the 455 Olds I swapped in had a 60psi sender. The gauge was NOT accurate. If...

    Need help with my freshly rebuilt carb

    It’s been 30 years since I messed with setting the mixture control solenoid on those carbs. If I remember correctly, there is a green connector somewhere near the carb where you put the dwell meter. Basically, you raise the engine rpm to 2500 (I think) and set the metering rod stops so the dwell...

    Under Dash Wiring Mystery

    It’s been a while since I put cruise on my truck. Let’s see how good my memory is!! The connector with the pink, black and yellow wires are part of the cruise control harness. It uses the signal from the vss to command the servo for throttle position. Somewhere in that cruise harness will be...

    TransGo shift kit install...

    Those pans with the cooling fins work well, but are a pain in the ass to clean. All the clutch debris collects under those tubes where you can’t get to it. As for the leak, there are lots of other places the fluid could be coming from. Look around the dipstick tube, the kickdown cable...

    High oil pressure after replacing pump

    There’s nothing to worry about with your oil pressure. If it will ease your mind, next time you change the oil, cut open the oil filter. Look in the pleats, if you see no metallic debris, relax. Use tin snips to cut the filter open, it’s hard to tell what is engine debris from shavings from a...

    rough idle

    If you ran it out of gas, and the problem started immediately after refueling and restarting, it’s probably got some trash in the tank or lines that got stirred up after refueling. You might be able to clear the crap out of the float bowl by pinching closed the rubber supply line to the pump...

    Under Dash Wiring Mystery

    The ribbon cable on the green book leads up to the optical speed sensor inside the speedo head. There is a wheel with slots cut into it, the optical speed sensor counts how many times it “sees” the windows in a certain amount of time. It then uses that to calculate speed. The 3 wire connector...

    Under Dash Wiring Mystery

    The green box is the VSS (vehicle speed sensor) buffer. Don’t throw it away, you will create more headaches. Look for a ribbon cable that runs up to the speedometer. One the opposite end of the box, you will find a place for the plug with the pink, black, and yellow wires. The speed buffer...
