tried searching but ran across a buncha topics that didnt answer this question so: i have the momentum turbo kit which routes exhaust through the drivers side and i got an aem wideband and the cable isnt long enough to go through the passengers side battery spot and back over to the exhaust on drivers side, is there any other way to route the o2 cable other then drilling a hole on the drivers side through the firewall?

 

I ran my cable thru the hole in the lower fender well for the rear window sprayer tube.

 

How about through the shifter opening? Just make sure to seal it tight.

 

On my AEM I extended the cable with 18G wire.

For my LC1 I drilled a hole in the transmission area. THAT cable is short.
