I was checking the injectors and inlet manifold to make sure no nuts had come loose, on removing the large 90 degree rubber pipe from the fuel head, I found this plug, it was located close to the lambda sensor plug, the male side casing has come off and im now left with 3 pins, i can glue the casing back on, problem is im not sure which way the pins sit, the plug has a marking one side and no marking the other, can anyone please confirm which way the plug connects, is the marking on the same side as the metal pin that is pushed down to unlock the plug or the other way around, dont want to put it in incorrectly and cause short and damage something.
That should be the connector from the rpm sensor for the EZ69. Unfortunately, the pins are difficult to identify because no cable colors are entered in the wiring diagram.
Try the following:
Plug the connector together so that you can still reach the contacts with a measuring tip. Then pull off the small of the three round plugs on the EZ69 and measure whether there is continuity from the outer socket (ground) of the EZ69 plug to pin 1 or 3 (the two outer pins) of the rev sensor plug. If not turn the plug 180 degres and try again.
To explain: The ground for the plug on the EZ69 is on pin 3, there has to be continuity to the ground socket of the EZ69 plug.
If anyone can take a pic of their plug that be great as one side is marked and the other blank, as in pics.
Fritz so pin 3 is ground on the ezl plug, does the end of the ezl plug terminate at the pink coloured plug or the side that has broken and exposed three pins
The three pins I will then check which one makes continuity to ground
Dont want to get it wrong and fry the EZ69
The male part of the plug belongs to the wire of the rpm sensor, the female part goes with the cable on the EZ69.
The rpm encoder signal has a shielded ground that is connected to pins 2 and 3. These are connected to the outer socket of the connector on the EZ69. Correspondingly, pin 1 is the positive line of the signal on the center pin of the EZ connector.
I'll look at it again this afternoon on the car, unfortunately you can hardly get to it when everything is assembled.
If you could take a pic of the plug that would be great .
A pic of the side the pin is pushed own would give me an idea of which way it fits as one side has a logo and the other side has nothing
So pin 2 and 3 are earth, we are trying to locate which one pin 3 is, or have i got it wrong
ha! that connector broke on my car when I first got mine. Only time the car stranded me in 11 years, almost 60,000 miles of driving. Of course the good people here on this forum knew what the problem was, told me, but being as new as I was I didn't put 2+2 together. Had I understood, known what I know now, I know that I could have driven the car! and been able to say it's never stranded me ever. Oh well.
