Does anyone have a part number for the C206 body connector? I have been in to the dealers today and they could not find it on their microfiche.
Are there any other GM cars WITHOUT the LS1 that uses this plug? maybe i can get one at the local pull a part. I know they do not have anything LS powered

I'm using 2004 gto stuff too. Looks like the bcm controls the low speed fan and pcm controls the high speed. Any one figued out a way to run a low speed. Thing of wiring it to an unused out put such as ac, evap, egr and tune it to activate at certain temp. Any other ideas.
Mark VIII fan on my 69 bird. Has never been on high speed yet. I also got the Hollister relay system. Very well made product here are a few pics.
Mark VIII two speed fan
Hollister Relay setup. This is a really robust system with high quality relays and wires. They added an extra relay to activate the fan when the A/C is on
Installed with a PRC radiator

I was going the Mark VII fan route and canned it because the factory relays could not handle the load of the fan. I ended up buying a 4th gen rad and using the factory fan setup. I have the setup if anybody is interested for $100
