I am relatively new to 75 ownership and still finfing my way around the electrics.
Got an ignition gremlin I am trying to sort out.
Does anyone have any illustrations of where the actual location of the earth connections under the dash of a 75 series are? If no illustration, a verbal description would still be helpfull.
Thank you.
Unfortunately this is a LHD version, but I think it makes it clear as to the locations of the earths.
But seriously, I've only found one myself, and that's on the 90, possibly the same? Passenger side, behind that "shelf" they have on the 75, where the briefcase would be on the 90 (hmmm). Behind the carpet, but you wouldn't have to pull it too far down.
Thanks Sheldon.
I have examined the photo and marked a couple of possible earth locations. Would you agree with these two sites?
Also is the ECU in the passenger side footwell?

It is in the 90, I'm assuming it is in the 75, most things are identical.
Have you seen this site, it has manuals you can download. http://www.users.on.net/~craigf/ (http://www.users.on.net/~craigf/)
Thank you.
Has anyone got any info regarding the earth points?
I have multiple electrical problems; mirrors, radio, heater fan, rear window heater, headlights flicker with indicators and so on... not sure where to start because the wiring diagrams are a pain in the ass to read and just confuse me
Thus far, the ones I've found are:
Engine bay: above each headlight, pretty obvious, for all the small wires (G53a and G53b in wiring diagrams); battery-chassis wire; engine block to battery
Behind dash: driver's side, well above fuse housing; only became obvious once I removed the dash, and haven't attempted to reach it with dash in place
Under rear seat: passenger side, just near speedo pulse amplifier; probably one on the driver side too but haven't looked yet (?G63a and G63b)
I haven't looked in the boot yet!
The headlights, front parking lights, and front indicators all ground to those points above the headlights.
Side indicators and rear lights ground at the 'rear ground' points, which might be G63a/G63b, unless there's other points in the boot.
Rear demister grounds at G63a, 'rear right ground'. Again, might be the one under the rear seat.
Radio + HVAC fan, and expect the side mirror, ground at G52, which is the ground point above the fusebox.
:)
Thanks shiny! Will nail those tonight to clear those up and then start tracing wires around...
