Re[2]: Shogun Pump Wiring

To begin, the old OEM after run pump and fan appeared to work 
as intended. I decided to change the after run pump as 
preventive maintenance, using the Shogun coolant pump as 
several other Listers have recently.

Here is the deal. I planned to remove the old pump, plumb and 
wire in the Shogun pump using the wires which are there with a 
new connector but no relay, and then run the car to get things 
warm enough so that the after run pump and fan would cycle 
once I shut the car down. That was the plan. 

I plumbed the pump into the system. The only challenges there 
were getting 0.75" barbed fittings locally and angling things 
enough to avoid bending either hose too far. I would have 
liked to have a 45 degree fitting on the inlet side of things, 
but I felt lucky enough to find straight 0.75" fittings.  The 
plumbing was not that difficult.

So, on to the electrical. Removed the old connector from the 
after run pump wiring. I found two terminals, with three 
wires, at the OEM connector for the after run pump.  

Two of these wires (both red) went to one terminal and were on 
what appears to be the positive side - I assumed one wire was 
hot and one going on to something else. My volt meter agreed.

I assumed that the other wire (red w/ blk stripe) was a 
switched ground - however, when I check things with my volt 
meter, I find things are always hot between the aforementioned 
red wire and this supposed switched ground. So, if I connect 
the after run pump it will always run.  However, the after run 
fan does not run (unless I cross the wires at the temp 

Is the ground indeed switched for the pump? Where is it 
switched? Is it possible that this switch is stuck closed, or 
have I developed a short to ground somewhere on the ground 
side of the after run pump circuit? 

Recall, the old OEM pump was working fine. With this in mind, 
I rewired the old pump into the system, only to find that now 
it also runs continuously.

Does the same relay that controls the after run fan also 
control the after run pump? Where is the relay for the after 
run pump located?

Why is it that the easy jobs always seem to go awry?

You can, but don't try the pump without pressure in the coolant system. the 
load is too high and it will pop the fuse.
Let us know how it works,

Can I wire the Shogun after run pump without using a relay?

How do I wire this Shogun pump?
