Wireing Gauges

[Deadeye_88]

is it hard to wire up all your gauges? i have read the instruction and it sounds confussing. anybody know how to wire them up that would help me out? i only have the egt and boost gauge.

ive done it before on my chevy, an i will be doing prolly this week on my truck now. i dont think it should be to bad if you have a voltmeter to find power wires

[Deadeye_88]

i have read that you need to hook up the wiring to the fuse box using a kit?

[redracer62]

ya i think that was the easiest place to get the power from

[Deadeye_88]

so hooking up the lighting, ground, and sensors not hard. the senors and ground will be easy. its the lighting. how would you hook it up?

[redracer62]

if you didnt care about the lights being on in the day time, then hook them up to 12v when the key is in the on/run position. or you could hook then up so when you turn you headlights on, they come on with them. if you do that youll have to find light switch wires an go from there

I done it on my 96 f250. I tapped into my lights at the switch. Take a test light and probe which is hot with the lights on. Then you can probe which one dims the interior lights. My fuel tank selector is right beside my headlight switch, and I tapped into it for my 12v power source. You can also use a multi meter to probe the wires.
You can tap into the fuse box using a "tap a fuse" I know my local Twlight Zone carries them.

yeah here is a pic of the add a circuit i did on my truck for power to the guages

if you follow the directions, it will tell you where to tap into for power. you dont have to have a test light, the wires are all color coded, you ll just need to tap into the illumination wire found behind your switch assembly. for your 12v power, there is a customer access wire under the dash, by your OBDII port, that is alread cut for these kinds of needs. there is no need to tap anywhere else. i believe the instructions talk about that wire. as for grounds, you can put al the grounds together and find a common place to ground the gauges. it is real simple, i know it seems overwhelming but it isnt. i would not tap into the MAP line for the boost gauge, i would drill into the intake elbow, you will get a better reading and no flutter in your guage. the tranny sensor is real easy. the pyro, is a bit tougher, but not impossible. make sure you tap into your manifold, drivers side, close to the back of the manifold. you will get a more accurate reading there. if you have any questions let me know. ill help with what i can.
