alright, i already got my heated o2 sensor from discount auto... now here's my question. i know one white wire goes to ground, the colored wire goes to the ecm, and then the other white wire goes to an accessory only power wire.... does anyone have a pic of how they connected the white wire to an accessory wire or the fuse box? i don't have any examples to go on and since im doing this with a lot of afro-engineering, i don't wanna mess it up anything you guys could help me with would be greatly appriciated.

 

Cummon haf, just jigga rig it. JK, give it to your mech. Tell him to put him on while hes doin your rebuild.

 

I wired mine into the cabin and then hooked it to a switched hot source. Found a fuse and checked it with a test light. Find a few fuses that are not ECM or INJ switches. Basically accessory fuses. Check with test light if it is hot with key off. If not, turn key on and see if it is hot. If it works that is the positive you want. The negative can be any ground source including the engine block.

 

i'd rather do it myself,

aklim: how exactly do i connect it though? thats what my problem is... i know to connect it to the fuse, just dont know what i need to do to connect it since ive never dicked with my fuse box before (except to replace blown fuses)

 

Quick and dirty? You can place the wire across one of the fuse blades and push it in place.

awesome thanks aklim, thats all i wanted to know

 

If you really wanted to get slick, you could simply cut the wire going into the fuse block of the fuse you selected and solder a positive in it but that is unnecessary.

 

I found a switched 12v source under the hood, and used a splice to connect the two.

For me, it was the 12v wire to the charcoal canister. Not like its hooked up anyways

 

the charcoal canister is the black thing on the front left side where the light is right?

 

yeah, mine is on the drivers side behind the headlight.

 

is there any way you can take a pic of it? lol

 

Is it constantly hot or switched hot. I wouldn't think the cansiter would have switched power to it all day long.

 

I dont' have a pic of it now, and its dark out, so perhaps another time

it has a switched 12v source wire, the purge cycle is controlled by the ecm when it grounds the module like it does the fan relay

hope that helps

or you can tap into the switch 12v source for your fuel pump or cooling fans. I'd rather mess with the wiring going to something much less important, but thats just me
