Default CSR electric water pump install?

Any good write-ups? I suprisingly couldnt find anything that hit the nail on the head here. I have the mechanical pump off the car already, and the new EWP has already been modified to fit in the housing. I just dont know what to do with the freeze plug and the two electric wires coming out of the electric impeller??



What de Hell?



Thanks for any help cant wait to get the damn car back together.

freeze plug goes in back of the waterpump housing where the impeller was.the to wires are blue + and black - you need to set the + off a relay wired to your ignition.

1 1/8 freeze plug, put it in from the front.

Blue - Positive
Black - Negative


Run the black to the radiator support ground right next to the CAI and run your power to the air pump fuse in the underhood fuse box. Or to another switched source.

For reference:

Pink
- 12v Switched
Red -12v Constant

also check the 4 allen bolts in the front of the water pump motor. they have been known to back off and ruin the bearings inside.mabe locktite them before the install.
