Heated o2 power source

[Prospeeder]

Ok, i read up on 60*V6 on how to do it, but for us TGP guys, what/where is the wire to use that we can have 12 volt power only when the engines running onthat side of the engine near the turbo? I want to do the heated 02 someday and just wanted to know, mabye help other people too

I have a heated O2 in mine and i ran the wire from the fuel pump replay which is a accessory 12v with the key on.

now my Cutlass has that relay on the passenger side but i believe the TGP's have it on the drivers side where the positive power post is.

just connect to that for +12 accessory for heat, if its a 3 wire O2 then one is ground and one is the signal wire to the ECM

on my 3 wire AC Delco O2 there is 2 white wires one positive and one negative and one black wire which is the ECM signal wire.

just a heater so no matter which white wire goes to positive or which goes to negative just one on each.

simple process

wouldn't you rather have a power source that's hot in run rather than hot when on? I wouldn't want it to be being heated if i'm just sitting somewhere listening to the radio..

[Prospeeder]

oh thats a good point gutlass, anything you suggest for a place to wire it?

[GutlessSupreme]

I'd have to look over my diagrams quick, can't think of where specifically off the top of my head.

Why would your heated 02 be heating if you are listening to the radio? Only time your fuel pump/heated 02 will run is when the key is turned forward to the ON position. If you wire your stereo properly you should be able to turn your key back towards you (ACC) to listen to the radio and the ignition is not active nor is your fuel pump. :icon_cool:

The key or switch should be: ACC, Lock, Unlock, On and Start.

ACC: power for radio.

Lock: remove key.

Unlock:Steering wheel will move.

ON: Power to fuel pump and ignition.

START: Power to starter.

That's what I meant... ;) :icon_lol:

Edited my post...got ACC and Ignition written wrong. :icon_redface:

Well, I'd forgotten about ACC, but I knonw that I've had certain times where I needed the car "on" and not just in ACC.

[GangstGP]

I used the "purple" wire ;) anyone know which wire is the purple wire? sy/ ty guys?

[Invasion1]

my O2 does not come on when in ACC mode and nether does the fuel pump.

only with the key ON turned forward and when engine running.

sorry i wrote it wrong above.....it was 4:00 am and all  :laugh:

[Prospeeder]

ok im still a little unclear on where to wire the power source

[Invasion1]

fuel pump relay 12V

test light or meter and find the power wire or tap it from the relay or fuse itself.

[GangstGP]

Its kinda still up in the air, The leads to the fuel tank are hella long and undersized so you really dont want to add stress there because they are prone to melt in your gas tank :icon_eek: and the purple wire is undersized and known to catch fires on starters. so unless you upgrade either one you are risking either burning up the engine bay ro having your car explode, you choose. :laugh:

[GangstGP]

That might be a good thing :icon_biggrin: my engine bay burn up and Invasions car explode then we both can start over the correct way :laugh: :laugh: :icon_razz:  OOOOH SNAP!   unpimp your auto!
