Electric fan wiring question

[02slpSS]

In your post #14 pic I can clearly see 2 black wires that appear going toward the top of the pic. They are located directly left of the wiring plug in the pic. Yet in your newest pic posted it does not show 2 black wires?????

lol no your mistaking the shadow from the small blue wires in post #14 that's why I took a better photo, this is my Delima I don't know exactly where the black wires with the eyelet connect to in the wiring harness from the looks of the wiring diagram the eyelet looks to just connect to the black fan wire but I know the eyelet is a double wire so I know it connects somewhere else I just cannot tell where exactly.

Happy Holidays to everyone

The black wires need to be long. The black wire from the right fan, buried in your fan harness that needs to be opened up to find it, needs to be extended, as does the black wire from the relays. They connect together at a ring terminal that gets grounded underneath where the bottom of the radiator is, near the passenger bumper bracket.

Yes, there should be a double ground wire on the OEM harness. It's a ring terminal with TWO ground wires on it, one of those leads up to the relay/fuse block, and the second wire goes directly to the plug for fan #2. That plug has a blue and black, the other fan has gray and yellow wires. From...

Perfect thanks for the thread link Scotty hit it right on the head as you said, "So in a nutshell, you just need a good ground wire ran to the black wire on the relay/fuse block and to the black wire on the second fan plug. If you want to run two separate grounds with two separate ring terminals, that will be perfectly fine so long as EACH one is firmly bolted to the engine block or to the frame."

Your previous electrical diagram shows one of the ground wires coming off of fan relay #3(socket) and the other black wire comes from the Right fan. The end of those 2 wires would then terminate into a ring terminal. The wire coming from fan relay #3 socket is in the wiring harness that you have attached to your relay cluster of sockets. The wire is black and goes to terminal A1 of relay socket #3. The other wire is in the harness going to the right fan and it is black also. Both of these wires were cut and the rest of the wires were left behind in what I assume was a junkyard donor vehicle. You will need (2) wires same gauge as what you have going to the previous mentioned black wires and just extend them from the cut wires and run them both to an eyelet and ground it to the frame if you dont know where the original spot that it was grounded to. I would solder the wires and heatshrink them when you extend them just for the corrosion protection.
