anyone know where in the o2 sensor wire i should tap into for the gauge and which sensor will be easiest to run wire to? would it just be the one after the in my x-pipe??
Mr Grady is right-on.
At the puter, it should be 43 (red/blk) for the left side.
And 44 (Gy/LB) for the right side.
You can use a SPDT switch to toggle between both banks. Radio Shack sells a very compact 10 amp switch for a few bucks that works well.
BTW, what do you have after your X-pipe? Shouldnt be nothin' back there.
Good luck.
So how does one safely tap into these connections
The idea of cutting and splicing into the harness lead doesn't sound like a good idea to me
Are there special connectors available for this task
sorry i mistyped. i was talking about the sensor in the x-pipe after the headers. so i want to tap into the pcm. that is on the driver's side underneath the dash correct? and i would use that switch so i can get readings on all 8 cylinders as opposed to just 4??

It's not hard to do at the puter if you can work the harness around to access the wires (they are on the passenger side outer circumference of the harness). One could bare and solder a leg onto the existing wire (nice because the integrity of the OEM wire should not be affected) or use a scotchlock.
With all your mods Toyman, I'd be lookin at a WB anyhow.
Is a scotchlock a connector that you place over the existing wire and when closed makes the electrical contact for the wire that is being tapped into
