    Dakota Digital HDX Install Write Up

    Very nice write-up! I have the VHX gauges, and really love 'em. I'm digging the larger and more colorful LED info screens on your set. Looks like you get more than one line of info on those, which is great. The VHX has smaller LCD screens, which are still good, but not quite as pretty. :D

    Should I go topless this summer?

    I'll pile on too. Here's where my hard top lives in the warmer months. Just barely clears the garage door, but it works! Not visible in the pic, but I use an el-cheapo boat trailer hand winch bolted to the wall on the far left. I just pull the truck in, stick the 2x4's under the top (after...

    Speed sensor question — 700R4

    Hope it all goes well. My DD gauge install was a slight pain, but I really love how it looks and all the extra features. I also added on a trans temp sender module for mine, which is pretty cool as well.

    Speed sensor question — 700R4

    You are correct - this is on the 90 Blazer w/ 350 & 700R4. Pretty much the stock setup. That green paper looks familiar, and I think was adding to my confusion about wiring up the speedo. But in the end was pretty simple: just the two existing VSS wires to the "SPD-" and "SPD SND" direct to the...

    Speed sensor question — 700R4

    I wonder if we might have different Dakota Digital models, because I have no mention of a DRAC in the docs for mine. Mine is the VHX, which wires up like this: The two wires from the OE speed sensor (VSS) go straight into those two ports on my DD box - no device in between. Apologies if you...

    Speed sensor question — 700R4

    I had the same question with my Dakota Digital setup with a 700R4. Since you already have the two-wire VSS sender on your trans, you shouldn't need the mechanical speedo converter. The way to hook it up is to run the two wires from the trans VSS to the "SPD-" and "SPD SND" ports on the DD box...

    AC Delco 15-33220 Replacement

    I did the same thing when replacing the heater core on my '90 Blazer a couple months back. I used ACDelco 155372, from Rock Auto: https://www.rockauto.com/en/moreinfo.php?pk=84489&cc=1061558&pt=6860&jsn=8

    Exhaust replacement- anyone do it without welding?

    Yep - once I saw how nicely the guy tucked up the pipes on mine, especially over the axle, it made me feel a bit better about the extra cash.

    Exhaust replacement- anyone do it without welding?

    FWIW, I was recently considering the same thing. I had basically a stock exhaust with a kinda bashed-up y-pipe and a borderline obnoxious turbo muffler. I priced out some kits, but ended up finding a local shop to do the work. They did a great job and put in a true dual setup w/ twin spun...

    What's the best way to drain the gas tank?

    I can attest to the "screen" (or whatever it is) blocking siphon tube access via the filler neck. I ran into the same hurdle when trying to drain the tank on my '90. Tried several hoses, but they were all denied access. Maybe it's just a TBI feature? But I assumed the same: anti-gas theft and/or...

    Rear wheel toe on 90 suburban RWD

    Just to toss this into the fray: I once had a Jeep Wrangler that had a light, but persistent pull to one side while driving. It became a severe pull when the brakes were applied. I naturally assumed one of the front calipers was sticking, so replaced both. The issue persisted. It ended up being...

    Pissing match

    Mystification unintentional. My response was in reply to someone else's post on this thread who stated his son had successfully used those. I had said I was going to try the Amazon units he recommended, so my reply was to say that I did... and they failed. Was just closing the loop there.

    Pissing match

    Well, no dice. I ordered these, or at least what I thought was those (https://www.amazon.com/dp/B09SBXXB8M/) , but they are too big for my headlight frame/housing. Short of semi-major surgery, I don't see a simple way to adapt them, so sending them back. Once thing you gotta love about Amazon -...

    Pissing match

    Oh, this might be what I've been looking for - thanks! I've got these oddball-sized headlights on my '90 Blazer, and have only been able to find one source so far, which is these: https://genssi.com/h4701-h4703-sealed-beam-led-replacement-headlights-2-pack/ However, I like the looks of these...

    TBI idle

    I should add that you only need to mess with the idle screw if it does not already idle in the 650-700 range with the IAC unplugged.

    TBI idle

    In case you still need some guidance on this, here are the steps I always follow to reset the IAC: 1. Ensure timing is set correctly, get to operating temp, & turn off engine 2. Put a jumper pin (paper clip) on upper right (last two on top row) ports on OBD connector 3. Turn key to ON position...

    Should i fix the TBI or go to carb? And what's this wire?

    I was gonna say the same thing. I was diagnosing what ended up being a mechanical issue w/ my 350 TBI, and bought a reconditioned ECM/PROM on evilbay for around $150. The ECM ended up not being my issue (was a flat cam lobe), but I did confirm it worked fine, so now I have a spare in case the...

    Reinstate Wiring for Washer Pump

    I was kind of figuring that my intermittent wiper issue was due to a bad control module (the one at the base of the steering column). I had read where that could be a source of those kinds of issues. And since they are apparently unobtanium, I had just written it off and was thankful for just...

    Reinstate Wiring for Washer Pump

    Just a followup note on this thread: After getting the washer pump installed and plumbed, I was pleasantly surprised to discover that the intermittent wipers now work! Before installing the pump, I only had the "high" and "low" wiper settings, which was fine. But hey, I'll take the bonus! So...

    Thanks Roger - missed this yesterday. Appreciate the help!

    Reinstate Wiring for Washer Pump

    Rob, you win the prize! I just went digging into that loom, assuming there were only wires to the lights in there, and *bingo* - one pink wire, and one white wire, just hanging out in there. I plugged those into the washer pump and all was right with the world. The pump now works with the...

    Reinstate Wiring for Washer Pump

    Here's what the inner fender looks like. I've even poked around in those cavities with an endoscope - the only wires inside the fender are the ones that go to the side marker.

    Reinstate Wiring for Washer Pump

    I ordered the washer bottle new from Classic Industries. There is a cavity in the back of the bottle where the pump clicks into place - no issues there. Just need to figure out where the 2 wires that go to the washer motor come from.

    Reinstate Wiring for Washer Pump

    Thanks Rob. Yeah, I barely know enough about wiring to almost be dangerous, which is why I (try to) proceed with caution in that department. If the washer motor wiring is still there, it is _well_ tucked away. It appears that the DS fender was replaced at some point, so I'm thinking they just...

    Reinstate Wiring for Washer Pump

    Hello to all. I'm finally getting around to trying to get some squirter action on my '90 Blazer. My problem is that all the PO left of the washer system was the rubber tubing and the nozzles. The washer bottle, washer pump, and the pump wiring/pigtail are all AWOL. So I've got a new pump...
