O2 Sensor Wire Relocation?

[CajunKenny]

Hey guys and gals!

I was just wondering of anyone has relocated their O2 Sensor Wiring from the stock location. I was considering routing it in a different direction to get it away from all the heat of it's current route.

The added length of wire wouldn't be enough to cause signal loss issues.

Anyone done this...is it a No No??

I had planned to route it in a wire sheath through the fenderwell, and back into the car. It's on my long, long list of things to accomplish in the next 300 years or so...

Think of it this way, it already has super long wires coming from the glove box area, wraps around the back of the motor, between the intake manifolds, around the front of the motor, then past the distributor/cps area, and finally to the actual sensor.

I think no matter how you re-route the wires, it'll be shorter.

youd think it would splice in right before the harness hits the firewall, save maybe 2-3' of wire for the bean counters....

The circuit labeled "OX" coming from the sensor has to make a stop at the diagnostic block by the battery before making it to the ECU.

good catch aspec, didnt consider that!

Thanks man. I just had to chase down an intermittent short to ground on the "OX" circuit and thought I'd share. :icon_bigg

Good stuff Aspec!

Thanks guys...

i havnt worked much with the 7M motors, but were you just going to relocate the wiring, or would you relocate the sensor it self in the exhuast stream and all too?

A good O2 sensor has a sheath over the wire..., and it hooks in under one of the pipes right there. It's not as hot as one would think...
