Circuit 150 Splice Location?

[87ChevyV20]

Can anyone tell me the location of the circuit 150 splice location?

And, is it the same as the ground bus bar near the parking brake?

Thanks!

If this is the splice you’re looking for, it will be in each taillight harness. Find the ground screw connector, follow it towards the front of the truck.

What are you working on? The main dash harness is grounded to a 5/16 bolt at the right lower corner behind the dash.

Oh, sorry.

I meant the one under the dash.

The more I look at this, the more circuit 150's I am finding.

Looks to be near the fuse block I guess?

The main dash ground is up behind the left corner of the dash. With the dash bezel out of the way it’s easy to see.

What are you trying to fix? If that main ground was bad, I don’t think anything would work. Definitely not the radio or dash lamps

 

[87ChevyV20]

Yeah, wipers, radio and other stuff is inoperable.

So, I found what was causing this issue.

It had to be either power or ground and I was thinking ground because there was a splice that had a few of the inoperable circuits.

Well, it was the power wire.

Someone had cut the accessory wire coming from the ignition switch.

Go figure, but now my radio plays static!

You must have it on a news station.

Or, you may have inadvertantly loosened the antenna wire.

inadvertantly loosened the antenna wire.

No, it has the windshield antenna.

The radio could be bad too.
It is quite rusty on top probably with all the vermin leaving presents.

Or, it could be the connection to the windshield is rusted out.
