sensor to wiring using the extension cable
assembly provided. Install cable clamps on
transmission pan as shown in Figure 10 .
Make sure cable is routed and tied as far
away from exhaust piping as possible. See
Figure 10 for routing.
NOTE: Some motorhome chassis use an
oxygen sensor with a slightly different plug
that will not mate with plug on the Banks
extension cable. On these vehicles, file the
two plastic index pins off of the outside of
the plug on the oxygen sensor. Then file the
index pins off of the plug on the extension
cable that mates with the factory wire
loom. The plugs should now mate together
properly.
