I had ordered some compressor 'O' rings this last weekend. I only had one 'O' ring on my compressor. They arrived today, and were sealing washers, not compressor port 'O' rings. I spent about two hours on the net looking for a number to try to look up to get the correct ones. I located OEM # 02724674, which is AC Delco #1530169. I called O'Rrilly's in Huntsville, TX They had 9 in stock. 83 cents each. I drove the 32 miles each way and bought me 4 of these. If I was asking for these by application, 91 Cad Deville, AC & heating, compressor seals, etc they were not listed. I found this OEM number at http://gmpartsgiant.com/

This was a difficult item to find. I had been to 4 different parts houses trying to find these, I took my one in my possession, most said they had nevere seen one like these, as they are sort of oval shaped.

The guys at O"Riley's didn't even know they had these until I gave them the AC Delco number. This number was hard to find and might be helpful to someone else trying to AC their 4.9 using the Caddie's compressor.

I redid my wiring diagrams. They were produced almost entirely using information from this thread so credit is due to Mickey_Moose and others that helped get this out there. These are specifically for a 92' 4.9 single O2 into an 87' Fiero Gt Manual. Hope they are of use to someone. This is the second iteration and I have worked out the bugs but as always use at your own risk.

Very nice work Dizz!! These is the first true conversion diagrams I have ever seen. Complete will all the pin #'s and wire colors. Very nice!!

On the shift light. There may be a way to make it work but would require a change to the auto trans shift tables. I was able to make it sort of work at one point. The issue was it was way off for when it came on. I used the VCC pins on the PCM to accomplish this (F5 & F6). One of those wires would turn on the light for 1st and 2nd, the other did 3rd and 4th. I finally had to disconnect it. Light kept coming on at idle and stayed on in 4th gear.

Had to go through it pin for pin today for myself. I caught two minor things. A)Two of the pins on the TPS were labeled wrong. B) ECM B1 is always hot with C16 through the fusible link.

I have edited my previous posts download link to reflect this.
