OEM ground locations?

[SkyHighColorado]

What's pics do you need in particular?

sent from what use to be a great country...

one of the junction box telling me what does what. I know the cover has it labeled, but I don't trust it. Where does the battery connect to it? and where does the fuse box connect to it?

This would be easy if the PO and car toys didn't screw it all up. its a mess right now, I'm surprised it even works.

ok, so does the starter have 3 wires then? I cant remember since last time I replaced it. I have a brand new bosch starter in the house and it has 3 mounting points on it. So it should be the big main power wire from BAT+ to starter, the smaller wire from BAT+ to starter, and another smaller wire going from the starter to the junction box on firewall?

The 3 Wire mounting studs on the starter are labeled R, S and M. M being the main power supply wire.

Skylark, I found the location for the ground by the power steering pulley ( I have the power steering out at the moment). You wouldn't happen to know the bolt thread size for that ground do you? I tried several bolts with no luck.

3/8 course. I would used the holes on the passenger side of the block unless you have a drivers side battery tray.

As for the starter you use the "S" terminal.

Gotcha, thanks again for the great advise! Just to clarify, "S" goes from starter to junction on firewall?

The s terminal is the one that is from the key. It is the one that engages the solenoid.

Make sure all these grounds have nice clean bare metal under the lug.

Can anyone help with this wire? I am going with the assumption that it is a ground since it is on the frame...
