Default diypnpms2 1.5 93 miata having a hard time with the directions.

What's with the stars on the directions? Do they mean anything?Such as edge pin connection tps sig to adapter *gnd. Or when theirs only stars as the adapter like vref to adapter ***. I must be missing something.

Do I have this right ? Tps to the ground that's on the connector, then jump sig to gnd with 1k resistor. And if I have a wideband sensor to put in do I still do pin 4n to o2 on the board or do I just put the wideband signal into o2 on the board? Thanks for all the help guys

the oe TPS is just a switch and the MS can't use the signal.

You jump TPS to a ground through a 1K resistor to prevent the signal from "floating" while you drive. It's basically tricking the MS into thinking the TPS is always at 0%.


You can bring your wbo2 signal directly into 4N.

If you do bring the WBO2 into the OE wiring at 4N, then 4N needs to be jumped to the O2 pin.

Perfect do you think it would be ok the steel power and ground form the wideband controller for the gauge? Or would the be to big of an amp draw and make to much heat.

wire the db15 plug with 12v and GND from the pins very near it (next to the high drive circuit)

put an inline fuse on the 12v wire before attaching to the wbo2.

Thanks!! And please excuse me I don't. Have the board in front of me I'm at work. but are you talking about the 12v on the lower right side or the 1.5v board? And the 4 ground pins next to it

no.

there's a 5x5 row of pins near the row numbered 1-15. they have 12v, 5v, gnd, and snd there.

wire 12v and gnd to two of the pins on 1-15.

use your provided db15 connector to attach your wbo2 to there.

Thank you for clarifying that for me I wasn't sure if I could just use the db15 connector into the back of the ms

Braineack if you have a PayPal please send me a private message with with your information. I wanna send you something for the help. =)... I'm still confused on a couple things. Such as.... The tps ground with the resistor is that the ground above the proto area in the line of white grounds? Then also one of the signal from the lc2 controller does the go into 4n or directly into the o2 on the board. Then as for the other signal off the the lc controller can I put the directly into the 1-15 on the board to the db9 connector. And power and ground for the lc controller is their a spot on the board to get power and ground from? AAfter this it should be done thanks to you

it doesnt matter what ground.

I use the SGNDs when doing it.

I tend to jump 4L with 4D or 4C on the connector board.



the WBo2 signal must end up at O2.

so if youre using the db15 to bring the signal in, wire the DB15 pin to go directly to 4N. otherwise, if youre using stock wiring, wire 4N to O2.

I just told you exactly where to get power and ground. wire those to your DB15 pins. match the WBO2 wiring to those pins on the connector and you now have power and round to your WBO2.

TL;DR wire all three wires to the WBo2 to the DB15.


you're basically asking the exact questions I already answered. i cant make it any easier than drawing lines for you on a picture of a board. and i dont feel like doing that.

I'm sorry I was under the impression that the db15 was only for the o2 gadge only. I didn't realise that the whole time you where talking about the o2 controller wires are going into the db15 connector. Thanks again for being so patient.
