Trans codes thrown - No 12v to pin E - source?
Trans codes thrown - No 12v to pin E - source? Hey guys, I'm throwing codes for solenoids a, b, and the tcc. I repinned the 2003 LQ9 harness for a 2004 4L80e. I figured I damaged the plug in doing so, but I've found I don't have 12v to pin E.
I'm using the fuse block out of an 04 Silverado, where does pin E draw 12v from? If I decide to just run a new wire, what size fuse should I use?
Thanks

The power for the truck trans comes through the underhood fusebox but is actually supplied in a round about way through the interior fusebox.

OK, an update. Transmission power is supplied from socket F2 on connector C2 of the under hood fuse block. In a round about way that power comes from the in cab fuse block. Remove that socket from connector C2 and move it to pocket B9 on connector C2. B9 is fused by fuse #24 (ETC Fuse, not normally used). That fuse, and INJA, INJB and ECM1, run off of the same relay (IGN1 Relay), and therefore is switched 12V. Can't confirm that it fixed my problem, too late in the evening to start the Jeep with no exhaust...
