Hi, everyone. I'm a first-time poster here but have been on t4r.org and ExpeditionPortal.com for quite a few years.
My vehicle is a 99 4runner, SR5, 3.4, auto, 4x4 with the rear locker. Currently at about 142k miles.
Anyway, I've run into a problem that I can't seem to find an answer for. I did a search but couldn't find anything that helped.
Here's my issue: I want to install an aftermarket outside temperature gauge so I know the temp outside (most modern vehicles have these but my 99 SR5 doesn't.) I've been running a cheap outside thermometer for the last couple of years, but it has a few drawbacks, primarily they are that I can't see it at night (not backlit as it runs on a single AAA battery) and it looks like crap stuck on my dashboard.
Now I know they make those mirrors with the outside temp display, but I don't like them. They also seem rather expensive (around $150 from what I've seen.) So, I went ahead and got an aftermarket electric 2 1/16" gauge and a pillar-mounting pod from http://www.egauges.com
Now I'm not a mechanical whiz by any means, but I can operate a screwdriver and a pair of pliers. However, this install has me a bit confused. In order to install the gauge, I need to tap into 3 locations: A ground, a 12v power source that is only powered when the ignition is on, and a source that is only powered when the lights are on (to activate the 'dimmer' on the gauge.)
Seems to me the ground is easy - I should be able to ground to a body screw or bolt, right? But the other two - where and how can I find the correct wires? I have had the lower dash off my 4runner before, so I know where the fuse block is, but it just looks like a mass of spaghetti down there. Not only that, the wires are tiny - I'm afraid of trying to cut into one of those little wires for fear of screwing something up in the truck that would cost a lot of $$ to fix.
So, any tips as to where I can find a couple of wires to connect to? Has anyone out there installed a similar type of aftermarket gauge into the driver's side A-pillar?
Thanks in advance. If/when I get this figured out I'll make sure to take lots of photos and post it up in the appropriate section of this board.
