View Full Version : Oxygen Sensor Extension Harness

I am in the middle of the header install on the '91. I can't get to the wire harness except to plug something in. There just isn't any room down there. So I need to extend the O2 sensor harness on the right side about a 1 1/2'. I can probably get the weatherpack connectors from NAPA, but advice on the wire size,type and any other information (especially the no-no's) on this would be appreciated.

John, you can get the OEM weatherpack connectors through NAPA. When I built my 02 extensions I went to NAPA, and they ordrered them for me. I picked them up the same day right down the street at an AC Delco parts warehouse (lucky for me it was right in town!). I might have an extra extension laying around. Seems to me I bought an extra one. Let me check tonight and get back to you. Maybe save you some time and energy.

PM me the phone number your at and I'll get right to you. I'd like to get this done today if possible.
Thanks
John, good talking to you this morning. It sounds like you are well on your way to completing the header install. Have fun! :mrgreen:

Many thanks to Jeff, Nick and Marc for their timely return of phone calls.
I have made a harness to extend the O2 Sensor wiring. All the parts were available at NAPA and it was easy to make. A better crimping tool would have been nice, but mine worked.
A couple of pointers for anyone doing this from Marc:
1. The weatherall connectors are the way to go, there shouldn't be any issues doing the extension this way.
2. Marc said you can extend the existing harness but you have to use crimp connectors. If you try it by soldering and taping the connections the O2 Sensors won't work.
3. You want to use 20 guage wire for this job.
Now on to the completion of the job.

Started the car last night but haven't driven it yet, so we'll see about drivability this weekend.

It's about time. How can you wait until this weekend? That car will be totally different now. Can't wait to hear your thoughts. Ted
Oh, it only gets more expensive from here.....

Kinda looks like some valves have kissed that cleaned up piston.
Am I seeing things?

Given what appears to be rust on the cylinder liners and pistons I'd speculate head gasket/coolant leak problem with the possibility of hydraulic lock consequences.

Rusty cylinders. It was not put away (stored) nice. It looks like the heads were pulled and the water/antifreeze left in the cylinders. No Valves hit, just crappy pictures. Broken chain wear strips, alot of metal in the front cover/pan area. I will take it down this weekend, hope:pray that the crap in the front area is just crap that fell in. Not made from the bottom end.

Hey John
It's a 368 that SGC built. Mike of EES bought the car, then went on to build a new block 396. This short block has 4 or 5 k miles on it, was bought by Lee but never moved from Mikes shop. Lee thought it was clean enough to put heads on and go. The real deal is it's rusted and need a full tear down. Later today, I will see whats inside. I hope it will stay a 368, but whatever it needs to make it right and run again. If junk then it will be bigger 377 or 385. If I could find a good used Crank (385 or 402) I'd take it, Jeff....
