I screwed up big time....

[max]

Thanks, just thinking ahead; the pcv only connects to the neg 12v terminal ( for the injector control ) so connecting it to 12v pos would do no harm to the injectors.

But as i understand the pcv also connects to the tps on the side of the throttle body, the tps is also connected to ground at one of the 3 pins ( the black/green wire ) so putting 12v pos on this wire could produce smoke, it would normally set a fault code but who knows in this case?

according to my wiring diagram the tps ground runs from the tps through the 10 pole connector, changes to a green/orange wire and then connects to the common SIGNAL GROUND like all the green/orange wires do, this means there is no load current flowing through these wires and they are a small diameter as opposed th the GREEN wires which are load ( current ) carrying , they just are connected to one single point on the chassis under the tank.

I could well be wrong on this but without looking at it myself this is my best guess.

I would think this green/orange wire could have suffered a current overload, check with a 20 watt lamp connected to 12v pos if this is the case, thanks for the pdf.

Edit; the can interconnect cable also has a ground wire incorporated, does this look as if it has been overloaded?
