And so it begins....323BG hatch ----> V6 powa with a few extra surprises

[Dan [Sac]]

Still no luck. I got it to crank strongly by jumpering the starter + wire with the starter signal wire - it builds good oil pressure, so the engine is in ok shape. Back to the drawing board.

Anyone have a schematic with the '92 MX3 ground locations?

that's a huge picture lol

sorry to hear about the issues dan are you getting spark and fuel?

[Dan [Sac]]

Without the engine cranking, it's hard to get either.

All grounds accounted for, still same issue. I'm starting to get a feel that the new replacement harness might have some issues, but I'm not too worried about it. I might just rip it all out and go to paint now as I don't want to waste too much time on this at this time.

That's showing the 1.6 4-cyl engine & harness.


Edit - I found the 1.8 V6 one by clicking 'next' a couple of times. It's T-Y-029.


Edit 2 - thank you for the great link.

[solo_ryder]

Haha sorry. Yea, good call on looking ahead. I looked at that one too but it didnt click in my head haha. Are you getting spark at all?

[Dan [Sac]]

There is no crank rotation, so no spark. It has to be either a harness issue, an ignition switch issue, or a missing ground.

I highly expect it to be user error (missing ground or something unplugged somewhere though thus far I've traced everything proper).


The one thing I can't find on my harness is the JC-04 cluster ground - supposed to be by the battery somewhere in the stock location.

If someone can take a photo of this guy and what it connects to let me know. From the diagram it looks like it branches off the diagnostic box harness.

[solo_ryder]

Connects with a 10mm bolt to the frame rail right behind the battery.

its tucked under the clutch master cylinder, and is a PITA to get too

[Dan [Sac]]

I don't have it on my harness - I wonder if it 'fell out' while (or after) I unwrapped the harness from all the factory tape. Trip to the JY is in order now, I suppose.

The only other clue I found is that the dash backlights don't come on when I turn parking or headlights on (there are no headlights or corners or tail lights plugged in, but that won't keep the interior lights from coming on - unless something else was missing).

All other grounds are accounted for and grounded.

W....T....F....snow is forecast for tomorrow....mother nature is pissed!

[Dan [Sac]]

So until I find where that JC-04 cluster went, here are 2 pics of the gauge setup. First is the water temp electric sender plumbed in, second is of the gauges in action.

Still haven't decided on a location, though I think a 3-pod gauge on the a-pillar is the most sensible idea, though I hate that it will be so visible - which means I'll try to find something else. The boost gauge is not hooked up yet.

[monoxidechild]

why not put them above your radio. where the center vent, and clock is. you can fit 3 gauges wide in there, and its close to the rest of your gauges

[Dan [Sac]]

That's what I thought too, but then i have to relocate the vent outlets...and I likes my heat

if you use the mx3 center console you can use that little coin tray thing under the raido and it will fit 2 gauges easy and it can fit 3 as well
look at mine...and i moved them around so the raido is under them
