Subject: Re: 1985 C4 - almost frame off by Vette91 on 2015/4/19 11:21:15 Right now I am in the middle of swapping the '85 Corvette ECM to '730 F-body. Found the pinout of both at http://chevythunder.com/fuel%20injection%20ecm%20pinouts.htm The '730 pigtail I work on does have a few differences. For example there is: - no wire at A4 which should be MAP 5V ref. - no orange wire at A8 which should be "serial data" but it is at A9 - no wire at B6 which should be ground for CTS and MAP - a wire at B7 (not used in your pinout) - no wires at B9 and 11 which should be VSS input Found wiring diagrams at http://www.eecis.udel.edu/~davis/z28/ECMs/92-7730v8tpi-1.jpg I believe all '730 ECM should have the same "internal" wiring. So I have to reorder the pins of the pigtail I have in a way that matches the pinout of chevythunder and the wiring diagrams of eecis.udel.edu, right? Best wishes Eike |
