E-Fans for 99 silverado install
Im looking to install efans on my 99 silverado instead of a clutch system like i currently have. I have an hp tuner pro and have explored how to turn them on as well as adjust on-off times but Does any one have a recommendation on a fan part number or what vehicles have the fans i need as well as a harness i can buy to tie them into the factory harness. Is this all do able.

I bought some LS1 fans on tech for like $75. They don't bolt right in, but all you have to do is make some brackets that hold it up against the back of the radiator. I used some strip aluminum from Home Depot, cut and bent to shape, drilled a hole in one end, and bolted them to the upper and lower radiator supports where the fan shroud used to attach. Then I got a Nelson wiring harness for them.

Does the black bear harness tie into your factory harness. DOes it come with a wiring diagram. I would like to use a factory style setup so i can set them up with my HP Tuner.

It's a separate harness. You ground it at the alternator, get power from the red junction box, one signal wire goes into the PCM connector, and another signal wire goes to the A/C switch. All the connections are made on the left side of the engine around that red junction box; pretty simple to install. This is how the Nelson harness is installed, I assume the BlackBear is similar.
