Re: Question on 7730 ECU... (Sarkee)
My answers are within you quote.. the Notes for BA, BB, BC, BD, GE, GF the First B means Black, the G mean Green for the connector color. If you have a 7730 you have the correct ECM
Hope this helps
Well, I have the '86 7165 harness here (with ECU so I can read which are the pin #'s), and the 1227730 ECU, and Mike Davis' pinout diagram, and a corrected diagram from -=Jeff=- for a '89...
My question concerns the sockets...The sockets on my 730 are (left to right) -
-----------------------------------------
| 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 C | (this is the BC row 1-16)
| 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 D | (this is the BD row 1-16)
-----------------------------------------
-----------------------------
| 12 11 10 9 8 7 6 5 4 3 2 1 A | (BA row 1-12)
| 12 11 10 9 8 7 6 5 4 3 2 1 B | (BB row 1-12)
-----------------------------
---------------------------------------
| 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 | (GE row 1-16)
| 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 | (GF row 1-16)
---------------------------------------
The first two sockets are black & combined, although two connectors plug in. The third socket is yellow, with no letters.
I've read that all GM part #'s are interchangeable...But there's no "BD6" or "GE14"... :rolleyes:
It was free, so I'm not out anything...
But do I have the *wrong* 1227730???... :(

Re: Question on 7730 ECU... (Sarkee)
Aw, man, now I'm really confused... :confused:
So on the 730 side, the first letter is the connector color (even though mine is yellow not green), the second is the line, and the number is the position on that line...Yes???
CORRECT
And the yellow (or green) connector is E & F even though there's *no* letter???...
CORRECT, read it like the other 2 connectors
Here's my sticker data:
SERV. NO. 1227730 ADDT
861361 M530577514
I just took the O2 sensor wire connector off the donor Sunday (harness, no car), so I'm pretty sure it was an EFI car...'87 Cavilier 2.0 Auto is what the paint on it says...
...That sound right??? :confused:
(BTW: I found a pretty nice spreadsheet prog to print that out with - Thanks!) :D
