I have the engine out of the car, so I figure now is the easiest time to install the sending unit to the block. I found the hex nut that was behind the compressor, it looks like I'm going to have to buy another fitting/reducer so it will fit the kit.
1. After you guys mounted it to the block, what route did you use for the tubing? What is easiest and low-risk from heat/rotating objects?
I also have a lights and whistles gauge (air/fuel) and I haven't looked at it in a while, but I think it said to connect it to the lower o2 sensor. Now, I have MSDS headers going in with my 3L, and instead of installing MIL Elim's I was just going to disable my lower o2's via the prp/xcal2.
2. Will disabling the lower o2's effect the A/F gauge? Will it still work, just not be read by the PCM, meaning the gauge will work, or does it mean the gauge will not work.
Yes, I know an A/F gauge is pretty worthless unless it's wideband...but thats not really in the budget right now. Any info is appreciated.

You will hook it into the up stream o2, otherwise your different the purpose of the gauge. And be sure to send it to gadgetseller.com to make it more accurate and not just a light show! And no, the downstream o2s won't affect the a/f gauge.

Thanks for the info. I am sending my gauge to them tomorrow.
That solves 1 of my questions....still wondering how everyone routed their tubing for their mechanical oil pressure gauges from the hex bolt behind the A/c compressor to the firewall.

Related question to your post, do you have to remove the A/C compressor to gain access to that hex bolt? As my engine is still in the car and I would like to install my gauge there. Thanks.

buy a wideband 
The narrowband works to slow.

My engine is out of the car. there isn't much room between the two, I'd suggest taking off your serp. belt and removing the bolts holding on the ac compressor. If memory serves me correctly, its only 3 bolts then you can move it away w/out any problems.
And Tourige...gimme some cash and I'll buy a Wideband...

IIRC, you have to unbolt it to gain access, but not disconnect it.

Sweet I didn't want to disconnect the A/C lines and have R134a spraying all over. So what kind of adaptors have you guys used to install the sensor? I'm assuming I'm going to have to buy some 90 degree bends so I can screw in the pressure sending unit. Or will the thing fit in there behind the A/C compressor? It's the standard sending unit the big knober deal with the stud sticking out the end.
