Are you removing the mechanical fan? Or replacing the aux electric fan?
Losing the fan clutch, M20 rad, AC condenser, etc... Changing to M42 rad with pusher elec fan.
You should be able to power it from the stock wiring that went to the aux fan assuming it draws less than 30 amps. The on/off is controlled by the temp switch on the right side of the radiator. The one to use is from the 4 cylinder which is 80/88c rather than the 6 cylinder switch that is 90/99c. The are identical other than the switching temp.
Do the aftermarket fans have low/high or just one speed? If just one speed then I would hook the positive lead from the fan to both the high and low wires from the car harness so it runs whether the temp switch calls for low or high speed.

Why have hacked up wiring to accomplish the same thing? If you use the 4cyl 80/88c switch (61 31 8 361787) it plugs right in. The only wiring needed is to wire your new fan to black/blue AND black/green on his wiring diagram (assuming single speed fan) and change fuse 3 (on the car in his diagram) to a 30A. The fuse size change is safe because the wiring is the same size on both circuits. If you have a failed low speed resistor on your stock aux fan you can just bypass the resistor and upsize fuse 3 resulting in high/high rather than low/high.
About the Chasebay overflow, I am confused how you will use that? It is not a pressurized expansion tank. Isn't it made for a system with a cap on the radiator?
-
IWhats special about the z3m rad?
Bigger than m42, and thicker than the e30 6 cylinder radiator.
Where does the chase bay overflow plug in to? Never really thought about that.
-
It plugs into the nipple of a filler neck.
When the system needs to relieve pressure, the spring compressed in the cap ,the seal goes up/becomes unseated, and allows the pressure to go to the nipple. This allows the pressure to vent into the overflow=) You probably already knew that though

This thread need to get back to motorcycles.
Because it's spring and they are way more fun
-
I didn't know that actually, not too familiar with that.
So, where does the other line on the overflow go to? Back into the system I assume?

One of my current projects. Full restoration of a 1960's Honda S90. Have everything for it, just taking my time to do it right.

What do y'all think of my retro inspired black spoiler?
I like it!
those Fuchs TJ has would work really well with that look too.
