Default High Speed Fan switch for L27

Will the high speed fan switch packages designed for the 97+ Grand Prix'* work with L27'*? Was the wire harness the same or did it change?

Holy crap why would you spend $90 bucks on that. Dude go to schucks and pick up 30feet of wire for $2.69 then a relay for erm..i forget, cheap! then a $2.00 switch and $1.00 in connectors. Pull the harness from your fans and hook the wire with connectors to it, they'll clip to standard "blue" connectors you can get at the store. Route those to the relay and into the cab to the switch you have ready to be mounted. Mount all that and hook to the battery. Boom, now you have control over the fans and you paid a couple bucks. I did this on mine so if you want a more detailed how-to I'll try and put one together.

The kits for 97+ won't work with Series I'*. They have a 4-wire harness, Series I has a three wire harness. I am selling one on eBay right now for that simple fact. I bought it way back when I didn't know as much about my car and just now got around to selling it.
