Ground connections?

[70jimmy]

Any chance somebody can tell me where all the ground wires are. My wiring is a mess and I am trying to straighten it out.

Also I located a couple places I think are grounds. One is on the left side bolt that connects the steering column to the firewall under the dash and another is on the fuse panel on a bolt that connects it to the firewall. Where do these connect to??

Did I mention I HATE WIRING!!!!!!

In my 72 I find factory grounds all over the place. Like the head light grounds are on the rad support.
All in all it should not matter 'were' your ground is as long as A) it's unpainted steel, 2) You have ground wires from your batt to the blazer body, from engine to frame & body. You could put one from batt/body to the frame.

I have found the 'over grounding' is a safe way to go. Simply put, with out a good ground you ain't gonna get power

I had a couple, like burt said, the headlights, and one on the passenger side, under the cab to frame, thats all I remember.

Factory grounds I have found are:
-battery to eng. block.
-pass. side exhaust manifold to firewall.
-passenger side rocker box to frame.
-passenger side wheelwell to frame.
-gas tank to frame.
-Headlight ground wires to rad core.
The rad core is grounded via the ground strap going from the wheelwell to the frame,as the rad. core is bolted to the wheelwell.

I still have those grounds plus I've added a ground from the eng. to the frame.Another ground from the drivers side exhaust manifold to firewall.Grounded my 2nd battery to the eng. block.
