Mpguino V2 info needed

I was americasfuture2k on here, started the enclosure thread.

I am wanting to install my old mpguino onto a 98 4runner. I cant find any info on my board or even which wire is which. This is the one with the phone jack (RJ11) next to the USB. I seem to be the only one with this board in existence.

Which wire on the phone cord goes where? Im assuming the RED goes to constant power (is memory lost when power is disconnected?), BLACK is ground, but which is which for vss and injector?

Also, does it matter which vss wire i connect to or which injector? IIRC inj # didmt matter as lomg as it was on the low signal, but vss.. i dont remember a thing about.

More also, what would my signal settings be for a 98 toyota 4runner?

Thanks everyone

hi mate, post a picture of the board and wiring and I can help. I'm not sure what unit or version of the mpguino you're talking about but I can easily help with some photos

cheers

VSS was the speed signal, and was either from an ABS sensor, or from the transmission.. (whatever the ECU was using was my guess).

I only made one, so I can't answer the OPs question about colors sorry, but, I do know how to find the answer..
The arduino is looking for a signal change, and so if you take a wire and repeatedly short and open it to ground, you would figure out what that wire does - you might want to do that with a 10K resistor between the wire and ground..

Also, VSS required calibration, different ABS sensors or transmissions gave out different signals and so you had to find the correct multiplier.
And Inj Pulse had the same task required. There used to be a page out there which gave some common figures.
