E-Fan Harness

[sparg93]

On your website I noticed you sell harnesses for the E-fan conversion...I have a '99 (OBS) 5.7L and I'm converting from clutch to a Mark VIII.

I'm not strong with wiring, so I'm looking for a complete harness with instructions for installation. My goal is a fan that automatically cycles between off-low-high due to the actual engine temperature.

Also, other then the harness, are there any additional electronic components I will need to purchase to accomplish the above?

I'm also thinking of attending the BB tune in NJ!

Thanks!

We do sell harnesses however for your year vehicle, you can only have one single PCM PIN and A/C compressor usage. You can not give staged fan operation based on various temperatures.

Thanks Jenna - I went on your site to purchase.

For single pin, you had a 2005+ option and an LS1 option...i'm assuming I would choose the later (LS1)? Also, do you recommend an underdrive pulley for this application?

I have a HD GM alternator (not sure of amp rating) and run a 1500W sound system, 35w (low), 55W(high) and 135W (offroad) light setup.

Thanks!

whoops...I meant overdrive pulley.

If possible, I need the harness by this Saturday at the very latest...would I receive it in time? (i'm in NJ)

Please let me know your thoughts and which harness I should order.

Thanks!

Ls1 or 2005 depends on the fan type. If your mark VIII fans use the same plug as the LS1 fan, that would do the trick.

Until your PCM is tuned to control the fans, the harness is of no use to you. Due to the type of computer your vehicle uses, an inperson tune would be a waste, as we can't datalog. A mail order would be your best bet.
