E-pump wiring?
I just bought a Meziere electric water pump and I was wondering if anyone has any recommendations/pictures on where they wired the switched power source to. I've already got the e-fan connected into the towing package relay slot. Could I solder the pump wiring into the wire for the fan that goes into the towing relay without overloading this slot? I'm not real crazy about using t-splicers into the factory wiring. Any suggestions? I've done a search, but the explanations were a little confusing to me. Thanks in advance for the help.

'McNasty,
Are you using any kind of relay for the water pump (highly recommended) or are you just using the wiring that came with the Mezeire pump? I went with the Mezeire wiring kit ($33) and it included a relay and the necessary wiring. The relay's power-on source is actually T-ed into the ignition-on power source wire for my JDM fan kit. I don't know if soldering the water pump's power into the e-fan's ignition-on power source in the towing relay is the hot ticket. If you use the ignition-on source you may overload it since the water pump draws a consistent 10 amps or so and that slot in the towing relay package is the one used to turn the relay on or off (which may not have the amperage rating that you need).
Hope that helps,
Dan

Struck in AZ,
The pump I'm using came from Jegs and included the Meziere pump, 40 amp relay, wiring harness and crimp connectors. Pretty good deal for $225.99 in my book. Anyway, are you saying that you taped into the power-on source for the fan that connects to the bottom of the y-connecter on the starter solenoid? Thanks for your response.

'McNasty,
My Mezeire relay is connected as follows:
The orange relay wire with the inline 20 amp fuse is connected to the bottom of the Y-connector on the starter solenoid.
The relay's black ground wire is grounded to one of the common ground points on the firewall.
The relay's blue wire (power wire) is run to and connected with the blue wire coming off of the water pump.
The relay's green wire (ignition-on) is T-ed into the gray wire on my JDM fan kit (that's the wire that runs to the fuse box and uses the towing relay space). You could also extend and run this wire directly over to that spot in the fuse box if you didn't want to T into another wire.
Lastly, the ground wire from the pump itself has a ring terminal on it and is grounded to one of the small bolts on the alternator bracket (I think they are 8mm bolts if I remember correctly).
