Hi all- trying to work out which wire feeds my speedo, as need to connect a Blitz power meter.

I took this pic, and was told the black wire pin 1 on the right hand block, but the black wire is no3, and has a silver dot on it.

I did try connecting the wire to that, but got no reading.

All help appreciated.

Cheers

There is a pinout on his site, but cant get the Blitz to read the ecu wire, so thought I would attack it from the speedo side

if the blitz is not picking it up it may be faulty, do you have a wiring diagram for the blitz?

is the unit simular to the apexi rev/speed monitor,

what inputs does it have for you to monitior

These are the instructions- http://www.japrace.com/images/instru...r-iD-Gauge.pdf

Im just trying to connect the orange wire- car is a 98 UK, so no convertors or limiters.

I did use JGM's pinout for the ECU side, and went for wire 3 in the middle block http://www.jollygreenmonster.com/pinouts.htm

but no joy either.

ok try these pinout

plug B135 pin number 3

plug B135 pin number 14


i would say the 1 to look for is a wire that goes from 0-5, as this is a speed pulse as apposed to a speed output, i would say plug 135 pin number 3,

Thats the pin I went for, but cant get it to read.

I presume it would read if it was wrapped together, but does it need soldering on?

try the oth pinout then b135 pin 14 you don't need to solder for test purpose, have you got a good ground and power supply

Pin 14 is definately revs- have dash shift lights conected to them.
