Wiring a Temp Gauge

[02ViperMody44]

I've done a search on this topic to no avail, and I was wondering if I can get some opinons on this. On a "12 Apex, I'm installing a temp gauge, and there are four wires on the gauge. Red-12v Accessory, Black-Ground, Yellow-12v Power and Green-Temp Sensor. Would there be any drawback to wiring both the Red and the Yellow to a Blue/White wire on the sled, which from what I've read would be keyed power once the engine is started. I purchased the Digital Water Temp gauge from Prosport. I could see why they would do this in a car, to check your temps. or whatever gauge you have hooked up, w/o starting the engine, but I don't really want to hook directly to 12v source all the time, fearful of power drain. Also, I'm assuming If I spliced them together and attached them to a singular wire, I should hook up an in-line fuse, but I don't know what amperage. On the literature provided with the gauge it is not written. Should 2amps suffice or larger recommended? Thanks for your replies.

Check out the above post by Ulmer, it's shows the installation and where they powdered up the temp gauge.

Thanks for the reply, so I'm ASSuMing that there would be no issue w/ tapping them both together on the same wire? Would you agree?

should be fine

I don't have a wiring diagram for that sled, but if that accessory wire is connected to anything else, the constant 12volts from the battery will back feed through the system and power anything hooked to it. If you hook it up that way, I would get a multimeter and check the current draw on the battery when everything is off. You could end up with a dead battery.

I thought he was hooking both to a wire that only powers with the key on (running). That would not cause a dead battery. Did I missunderstand??

My bad, I read it wrong.
I was thinking the red and yellow wires were coming from the sled, not the gauge.

Thanks for the help. I am going to be hooking it up to the blue/white wire that comes off of my SledStart/key interchange wire. It actually powers up when the key is turned to on AND the kill switch is up. So I would have access to the water temp w/o actually starting the motor. I'm also putting in a (3) amp fuse in line to the gauge just as an "in-case" measure. Mini ATM fuse holder w/ cover.
