Mystery Cable And Box

[JustinP]

I'm finally putting my car (R34 GTt) back together after many many years and I cant remember where the cable in the attached picture connects to?!

It's the earth lead that is connected to the battery with the middle of the cable connected to the chassis. Can someone help with where this end connects to?

Also in the second picture, what is that box for, the thing up behind the glovebox and above the ECU? It appears to be making a loud buzzing noise now that I have attempted to turn the engine over, even when the ignition was switched off.

Cheers

Thanks - I should have thought of searching for the part number...

I assume that controls the traction control butterfly, which is no longer present. I assume it will be OK to unplug and remove this alltogether? ECU is a Link G4.

Any ideas on the other cable?

So it either bolts to the block or to the underside of one of the holes in the plenum.

Thanks for the help, much appreciated.

I already installed another heavy earth cable between the chassis and the block, I guess I will stick that cable on the new plenum somewhere. I guess you can never have too much earthing!
