According to wire schematics there appears to be a ground wire junction block somewhere under the dash on square body Chevy's. My question is where is this junction block located under the dash?

Ground Wire Junction Block Location
- Thread starter 1-ton
- Start date
I dont recall seeing a junction block on a square body (my own trucks I had anyways)--there is a ground wire that usually has at least two wires crimped together to a ring terminal that bolts to the cab up near the upper door hinge though,which causes a lot of weird issues with the dash cluster and lamps if it gets disconnected ..
My '81 G-10 van does have a "bus bar" thing above the steering colum where several wires ground--none of the pickups I owned had one,but I haven't owned a lot either...some years may well have one..

My squares, 83 and 84 have a multi ground setup above the kick panel by parking brake.

Same with my 84
x2 location its got 4-6 tabs on it if I recall.
x3, my '85 has it same place. 6 positions.
That "Ground wire Junction Block", I was referring to seems to actually be the Instrument Panel Connector, which is probably just the group of wire s coming out from behind the fuse panel. I looked at both my 1985 K30 and my 1991 V3500, and and cannot see any ground wires in the location mentioned at the drivers side kick panel by the park brake pedal. There are supposed to only be three ground wires to the whole interior wiring system:
1. Coming from Instrument Panel connector
2. Coming from Light Switch
3. Coming from Key In/Seat Buzzer
Where the ground wires are actually attached to in my interior wiring system I do not know. My interior wiring systems are working good, I was just curious about the ground wires.

Because my dash is apart
I use that little junction block a lot.
Thanks for the pic. I will look for that.
I looked at my trucks, and I cannot find a ground terminal block like yours on my park brake mounting bracket at all.
I added it to my 74, didn't have one, pulled it off a later model at a yard.

Glad to see there is in fact supposed to be a ground wire going to it. Mine was missing that wire so I added it on there. Some of the stuff that gets overlooked on the old CUCV's absolutely amazes me. 
FWIW the "IP" connector is the one on the back of the cluster. I'd have to double check, but pretty sure my ground block is above the pedal bracket too, attached directly to the body.
I am going to have to look a little harder. There is some sound deadening material just above the park brake bracket, and maybe the ground wires are hidden behind that.

79 has same ground block as pictured above.
