    Is this part of the evap system?

    Good morning. Cleaning up wiring in my engine bay and not 100% sure what this for. Thinking evap system as the canister is gone and no air pump. Comes out of the dash between bull head for the wire harness and the steering column. Has electrical plug and a vacuum hose in it. Thanks

    Fuel gauge to tachometer, clock to fuel gauge

    How is it getting its power and signal if not running wires to it? Does it replace the sheet on the back? And put wire into the plug? Or did you replace the entire cluster?

    What aftermarket engine harness?

    I’m not in the shop at the moment. But it’s about 16” from the bulk head goes to fuse block. So I’ve figured out it goes to that junction block. I just no longer have the oem block. The pink one I’m about 99% sure goes to the fuel tank like mentioned above. As I found the original wire and...

    Wire identification help

    The one eyelet goes to the starter wiring. Appreciate the help. All my c10 experience was 67-79 models and didn’t have any of this lol

    Wire identification help

    So would both wires most likely go on the block? All the wires going to the black wire are red. Then combined to a single wire that’s black.

    Wire identification help

    Good morning, got my new American auto wire harness for my 84 c10. Checked pins on new harness vs old harness where connects to fuse block and matches up. But I have a few wires in new harness I’m not sure what to do with. I believe I know where one is suppose to go but someone changed oem stuff...

    What aftermarket engine harness?

    These are the wires I’m unsure on. I believe the red eyelet goes to this block on firewall. I saw in a YouTube video someone had a block but it wasn’t an expanded one like this.

    What aftermarket engine harness?

    Yea there wasn’t much instruction with the American auto wire….. quality harness just no road map. This one does not replace the fuse block. Just plugs into oem block

    What aftermarket engine harness?

    I ended up ordering from swclassics who get their harnesses from American auto wire. Seems good quality. Just wish things were labeled a but I know what 80% of it goes to lol. Are you familiar with 84 harnesses? That have the power wire going to a junction block on the firewall? I’m not sure...

    What did you pay for a square

    $400 from my father who bought it for $700. Was originally priced at $1200 and was suppose to be running driving truck. But they decided they could get $200 more selling the motor and transmission seperate. The truck than sat in my dads yard for 6 years before I said here’s $400 I’m taking this...

    84 C10 cluster swap

  16. 84_c10_GMC

    What have you done to your square lately??

    It is with a second rubber piece shoved under the main one. I need to raise the bottom of radiator up a touch. But with just the oem rubber and bracket. It comes down on top of the radiator tank and It does not hold the radiator in place. I have to double stack a trimmed rubber piece to make it...

    Here’s a picture of what I’m trying to explain lol. Hopefully this shows it good enough.

    What have you done to your square lately??

    More the entire bracket that goes across the top. My original brackets are about a half inch short of getting to the front of the new radiator. I got some larger rubbers to try and make work but I would have to cut the front lip off that holds the radiator in place for them to even attempt to...

    Fuel gauge to tachometer, clock to fuel gauge

    Yea this tach is simple power ground signal. And just need to knock a hole in back of judge cluster box for them to go thru. Thanks though!

    Fuel gauge to tachometer, clock to fuel gauge

    I’ll have to take a look but I didn’t think the summit gauges looked half bad for an oem style. LMC maybe cheaper though.

    What have you done to your square lately??

    Alright snapped a few photos before I run to orielly. Thing I hate the most is previous owner swapped the core support for the 88-91 front end…. I prefer the original 84. But it has a good grill and bezels so I may deal with that down the road. Need a couple front tires also and find my other...

    Exhaust Question

    I’ve always been a fan of flow masters but I haven’t bought anything in a good bit. The last time I did I happened to get the last set of original super 40s for my k5. But that was 20 years ago… My c10 currently has thrush I believe on it and it’s got a rumble when in the throttle but fairly...

    Exhaust Question

    You probably won’t notice much difference on a stock engine going to dual. Other than sound. A new quality muffler would probably be the best choice at this time, and least amount of money to get done.

    What have you done to your square lately??

    Haha it’s not quite shitbox level. But I’m just trying to get it moving under its own power at the moment and then decide later on if I wanna throw an ls in it or rebuild another 350 and put back in it. I’ll try and get some pics today.
