Schematic for rear mounted EBTCM (98)
New 1998 Vette coupe owner here, trying to track down a TCM-NO COM code. Can someone please upload the page from the service manual that shows the pinout at the EBTCM?
I found the one for the front mount here on the forum, but none for the rear mounted unit.
Thanks, this forum is a great resource.

OK, I pulled up two schematics which show the rear EBCM pin outs. Still looking for the Connector views but my info may not have that.
You need to PM me with your email so I can send them to you in PDF format.
PS: Do you need any of the information on code diagnostics?

Info sent. Let me know if you need anything else. Could not find the actual connector view but the schematics have the connector pin outs and wire colors.. Probably in a hardcopy version. Never seen an electronic version that had as much info as the hardcopies. The online data bases may be better.

Let us know how you make out troubleshooting your issue. Find the three fuses for the EBTCM and read the two test points on top of the fuses to chassis ground (ignition on). They all should read full battery voltage.
Check the EBTCM Ground Its a stud/eyelet ground in the passengers rear wheel well on the side of the frame.
Be careful as they snap off easy if you dont work it loose and spray it with penetrating oil.

Bill, After reading your posts, and seeing you were from Gales Ferry, I figured that you were a bubblehead. 
Thanks for the advice. Once I get back home from this out of town job (and reinstall the intake), I'm going to finish checking out this EBTCM issue.
