Question about gauges

I really like the look of the Pricol Optix gauges and I have read very good reviews about them. I have searched for an Oil Temp gauge by Pricol Optix and cannot find one anywhere. They make a Differential Oil Temp gauge... could this one be used for the Engine Oil Temp gauge? Here's the link.

Thank you

Bump.... does anyone here have an Oil Temp gauge made by Pricol? If yes, where did you purchase it from.

I have the tranny temp gage, but I wired the input to the gage through a two pole six step rotary switch from Radio Shack. I have the tranny, both diffs and coolant so far and will be adding engine oil soon. You can montior any parameter that falls within the 100-280 range of the gage, just find a point to install the temp probe and wire it up through a selector switch. I have still not decided if I want to wire up the second pole of the switch to give me indicator lights to show which parameter is selected. I have mini bulbs but maybe LEDs would be smaller and easier to mount.

Thanks for the post! I never thought of wiring a gauge using a selector switch. That is an inexpensive way to monitor temps. My truck is a 2004 so I don't have a stock boost gauge. With your idea I can purchase the quad overhead pod and get the boost, pyro, water temp and "share" tranny and oil temps and the diffs if I want to. Where did you mount the selector switch? Do you have pics of it installed?
Thank you for the knowledge!

I have the DiPricol Optix gages: tranny temp, boost, and EGT mounted left to right in that order. I used the three gage under dash mount. Using double sided tape I mounted two six land terminal strips at the back of the gage pod. For reference, if you looked at the gage pod unmounted and swung down like the lower edge were on a hinge, the "top" would be at the end closest to the dash and the "bottom" would be towards the gages.

The first terminal strip has the illumination power and ground landed to the top, each of which is jumped to two adjacent terminals for a total of three hots and three grounds. These feed the LED illumination for the three gages, and since I took power from the dash illumination circuit the gages dim with the dash control. Each gage wire is landed on a seperate terminal, this keeps things neat and looks like a professional install.

The second terminal strip has the +12VDC feed and grounds for the stepper motors of the tranny temp and EGT gages. This strip also has the input wire to the tranny temp gage landed on it, with the feed from the selector switch coming in at the top.

The gage wires are very small, I'd say about 20AWG. I used 12AWG for the ground so I just jumpered from the stepper ground over to the illumination ground terminals. Coming off the top of the terminal strips and going under the dash, I used quick connects. This way if I wanted to completely remove the whole gage pod I would only need to disconnect the boost gage tubing and unplug the wiring. The wires are color coded and I used a different style connector for each to avoid hooking things up wrong.

Now on to the selector switch... Behind the fuse panel cover I again used the double sided tape to mount another six land terminal strip. I used a two pole six position rotary switch from Radio Shack for my selector switch. I soldered six green wires to the switch terminals and one purple wire for the contact for each pole. The six input wires were landed on the bottom of the terminal strip in the correct order. I used a meter to verify this before cutting them to length and landing them on the terminals. On the top the various inputs were landed, front diff, tranny, rear diff, and coolant. Right now there are two open terminals, one of which will be used for the oil temp input wire.

I am considering using the second pole to power indicator lights or LEDs to tell which position(parameter) the switch is set to. In that case I would run power to the purple wire and the green wires would each go to a different light or LED. I could just set them in a row or maybe come up with a cute little graphic of a truck and have the indicator set up to backlight icons for the diffs, tranny, coolant or oil.

As far as the switch goes, I drilled a hole through the dash. It sits about two inches above the top right corner of the fuse panel cover and about three inches to the left of the top left corner of the cubby(which is right above the gage pod). It is just to the right of what looks like a small vent in the dash. I wish I had pics but alas.... such is not the case, hence the long winded description. I hope this helps.

This will absolutely help! You made it very easy to follow. This post should go in the tech folder, it's a great idea and explained very well. If you ever get pictures please post them in your gallery. Thanks again for the time in explaining this.

OK, if you look at the pic Riggz posted in the linked post you will see the little vent looking thing. I put the selector switch just to the right of it on that section of the dash. My gages would be where the compartment door looking thing is right below the upfitter switches.
