so I always sucked at electrical wiring and splicing
but never too late to learn. I know that the signal wire inside the black sheating cant be mixed with the shielding wire over it but where do the shielding connect to at the yellow round plug ??

 

It doesn't hook to the connector. The early 22REs have a 1-wire O2 sensor connector for the signal and the manifold is the ground connection. The shield is grounded where that wire originates but not at the O2 sensor itself.

 

Ok great. So I still crimp the shielding together for my splicing though

 

Yes, if you're extending the cable, it would be a good idea to extend the shield as well.

 

Bear in mind that the nice thing about shielding like that is that it only needs be connected to ground at one end or the other. You don't need a complete circuit for shielding. You just need to make the insulation of the signal wire to be at ground potential, so just one end, to drain the noise it picks up, off to ground. The more insulation that stays covered is important, though. The less that's covered in shielding is the more to allow noise into the circuit.

Many many years as a lead Radar Tech for an Aerostat (look it up: big, fat, balloon), not to mention being an F-4 Phantom II radar tech, gives you a lot of little tips and tricks.

Good fortune to ya!

Ok so if my ende look like that this; thats fine ?

 

As long as the shield is grounded at some point, an end, the middle, 1/3 of way along, somewhere, you're in good shape.

And yes, the shield is close enough to the end to function very nicely

Well I keep getting code 5 on my 22RTE... Changed the 02 sensor code came back. Test for ground continuity at the 0x wire, spliced it 3 times now about to buy this kit along with a crimping ratchet tool....
