I gotta do this. Especially since it's near-impossible to turn that screw with the computer being sealed in a box.

That's a great idea...will never do it...but still a great idea.

I'm starting on it right now. Hopefully the S12 connector is the same as the WD21. It looks the same, and I think the wires are in the same spot...we'll see...

Total cost so far.....$11

ooooooo look what i found!



Same as 200SX SE-V6(pretty much). I'ma go hook it up and see...

That's a great idea, Will!!

Let us know how it turns out. I might have to do the same on mine so I can watch for codes.

Currently, it's not working at all. No lights. Don't know why. There's hardly any(0.01) voltage running through the ones that are supposed to be for the lights.

More later...

THE LIGHTS WORK!

helps to have this...


Gonna try the mode switch now....

Very cool!!

Everything is wired up, but I can't figure out the switch. It seems like you would push and hold it until the lights started flashing for mode selection, but they don't. I turned the screw on the ECU and then the lights on the box worked. So at least I could do that.

Nobody will respond to emails about it. I'm too far into this to quit now lol

It is a mode selection switch.. I would think it would function just like the screw on the ECU. Youd have to hold it down until it flashes the mode # that you want to run in.

Yeah that's what i was thinking, and an S12 site confirms it, but mine won't work! I tested the switch and wiring and it's all good.

Here's pics of the progress...







I got a new camera

I don't know why or how, but it just started working!!! Lights blinking everywhere!

Done

awesome!

BLINKENLIGHTS!

That is a brilliant idea Will... good job!

Brilliant & Blinky!!

brilliant

I went and got all the parts today to do the same thing on my Pathy.

Would this work on my 87? I can figure out my ecu....it actually has a toggle switch to switch to and from diagnostic mode....but I can figure out how to select which mode.....no screw to turn as in the others....swicth on passenger side of ecu lights on drivers side....real pita to see.

POS still aint running either.

I have no idea if it will work on yours. I found the pin layout in the FSM for a 1994, but I don't have one for a truck that old

BTW, I've been driving around all day watching the lights

If anybody wants me to make them one just let me know. I might even try and find a connector that will fit into the check connector so it could just plug right up.

John, I'm using the RS LEDs that have a built-in resistor. I can get a PN if you want.
