Guage install help.

Some people on honda-tech told me i can just splice into the existing harness for the water temp, and oil preasure sending units and dont have to replace the sensors.

Ok, this is what i found out on ht.

Air/Fuel ---> Black wire: Any ground Red Wire: Thick red wire or thick black with yellow stripe on 3 prong conector for ignition Purple: Thick solid white wire on the middle conector of the ecu.

Oil Preasure ---> Tap into the existing harness and black and red are the same.

Water Temp ---> Tap into existing harness and black and red are the same

Volt ---> black wire: neg on battery, red to ignition.

here is my wiring diagram i made.

dont start a fire...

do not wire it ghetto....mine was wired ghetto and everything was fucked up.........starts fires right jim!

[Joel]

LOL true dat. Make sure you dont cut corners and use the right gauge wire for the current you are putting through it.

[Jim]

I know about starting your dash on fire. Its not cool.

I ghetto wired all of my street glow, my neons and shit back in the day and as I drove to the twin citeis the shit started on fire, iw as like OMG and i pulled off, and had to un hook everything. Not a big fire, but there was smoke, and the speaker wire i twisted togther was shot.

Just a headsup harwood.

only you would do that jim!

I am sure everyone has had there Twist and Tape Days of elecrical wiring.

i know i was just joking around.

This is actually a very smart way to wire the guages. This will have them light up when i turn the ignition on, it will have them hooked in parallel power wise and requires less running of wires under the dash which equals less mess.

[Joel]

You know there will be a difference in power delivered to the when running in parallel.
Read up on ohm's law before killing your car

All the guages will be at a different brightness. the first guage wired will be brighter than the last guage wired, since all the other guages are using the power.

thats only in series...parallel gets the same voltage for each load

Look at his diagram, the guage on the right will get more power than the guage on the left.

alls i can say is i had my gauges hooked up like that once...then one day my car started smoking from my volts gauge..and they all stoped working...all my wiring melted.

Actually i set the diagram up in parallel, with series i would have to take the groun off the first one and connect it to the power on the next and so on. the way they are connected is like taking one wire and splicing seperate wires off of it to connect the power to the guages. same with the ground.
