Update for anyone searching on how to wire a 6 cylinder aux fan after a swap.
So if you review the ETM (97 318ti + 97 e36 m3)for the m44 it shows the two step temperature switch low speed goes through the DME via x20 pins 3 + 8 (late model TI) and then it triggers the low speed relay.
On the 6 cylinder e36 cars the temperature switch does not go through the DME but directly to the low speed relay.
When I did a test and bridged the two pins on the body harness side and jumped the low side on the temp switch, the fan turns on. So in conclusion, I will be tieing pins 3 + 8 on the body side together to bypass the x20 and directly trigger the low speed relay.
The high speed relay is wired the same way on both m44 + 6 cylinder cars, so that was already operational.
Last night me and my roommate (already went through his e30 swap) went through it and came up with that.

Hi all,
Finishing up my s52 318 ti swap and have installed the 6 cylinder pusher aux fan. I have purchased Jim's manual and have searched the forum for tips or a DIY on how to wire the aux fan appropriately to run with the rad temp sensor + a/c on but have come up short.
Could someone point me in the right direction with a link or description on how to use the 6 cylinder aux fan ?
I would appreciate the help
