DIY Ground Harness (look correct? )

[RJTM998]

So I did a DIY ground harness and wanted to see if you guys thought it looked correct. One from the start box, one from the alternator, one from the firewall, one from the starter. All going to the ground on the back of the block.

I did end up using separate rings to the block ground instead of a central ring connection.

10 gauge wire, quality connectors, and shrink tube was used.

If I were to give any advice it would do each wire one at a time starting at the connection point, pull your wire to the connection point on the block and then cut. I ended up wasting some wire because I made some to long and ended up cutting so it would be a cleaner application without excess wire.

I did unhook the battery during installation just as a precaution.

Pictures showing each connection point.

Looks correct to me

Think I will be ok with the individual ring connectors instead of single central one?

Yea it should be all fine since its all grounded to the back of the engine block

I hit the back of the engine block with a wire wheel on my drill and cleaned it up to have good connection.

When you ground a starter, it should be 0 gauge. Personally, I would not ground the starter. I would however pass a 0-gauge from the engine block to the frame and body if you are worried about the starter ground not being robust. Then ground the frame and body to the batteries with another 0-gauge.

What about the alternator? I hear mix things about adding the extra ground to them

My mechanic "The Humvee Wisperer" said everything looked good. Guess I will roll as is.

If you buy one pre made it has that connection point and my mechanic said to do it. I can't say one way or another, I just go with the guys that know more than me.

If your starter isn’t grounded properly, you will burn up that wire like it’s a firecracker.

Do what you feel is right.

Pretty sure all the pre made kits use a similar wire setup. I am not saying you are not correct just going by what I have seen.
